SuperDrive scratching discs?

Not sure if I'm the only one experiencing this, so I'd like to get other experiences on this.
Picked up a new MacBook from the store today. I've burned a couple of discs and read a couple others, and was rather startled to see spiral scratches around the discs. Saw it on a DVD-R and a CD-RW that I've used in the drive. This is going to destroy my discs, I think!
Any other MacBook owners seeing this with their Superdrives? I'm not sure whether to take it to the Apple store and hope they'll do an on-the-spot exchange (does that ever happen?), or should I call AppleCare and send it in?
Thanks for your comments.

yes mine is scratching discs too with any movement. you can't be serious that they don't consider this a defect? first time it happened i wasn't even using the drive, i just moved the machine while one was in there. the disc became unreadable in the internal drive, luckily i have an external drive which could still read it.
i wish they offered an option with no drive, i have already bought an external dvd burner as the one that came with it is fairly worthless even when it isn't chewing my dvds. i bought this to replace my ibook which also had a worthless drive, couldn't even read the cds it burned (one main reason i bought a new macbook!).
i could also complain about their customer service, but i guess everyone already knows about that. it is upsetting because i am a loyal mac owner (on my 6th one) and always thought apple had a good product, but fear their service will take them down. seems like arrogance to me.
oh, i forgot my fix for the drive is a piece of scotch tape over the slot to remind me not to destroy any more discs (i guess another option could be to tape the computer to my desk).

27" iMac superdrive scratching discs

I have a 27" iMac which I bought about three years ago. Most of my movie media I purchased through iTunes, so there was no problem. Recently I purchased a BluRay movie which came with a "digital copy" which required a disc AND a redemption code on iTunes. I put the disc into the computer, it whirled around for 20 secs and ejected. I reinserted the disk a second time, same result. When I turned the disk around I noticed that the surface was covered with whorls of scratches. I tried the disk on two other computers which showed that the disc was now 'unreadable." I put a cheap CD into the drive to see what would happen and it came out badly scratched as well. Is this a defect in the iMac? The computer is WAY out of warranty by this point, although I am eligable for the 1TB Seagate Hard Drive replacement. If I need to have the drive replaced what is the cost going to be? Or is there any external drive that can be suggested that I use? I would LOVE to hook up a BluRay disk drive, if possible. I am sure that it would look AMAZING on the 27" screen.
Thanks.

Apple does not support BlueRay therefore your Superdrive will not play a BlueRay DVD. If you would like to purchase a third party external DVD blue ray dvd drive and an application for BlueRay it should work.
However on the scratching it sounds like the Superdrive either has something in it or is broken and needs to be replaced. I'd recommend taking it into your local Apple Store or AASP for service. Another solution is an external drive, this would probably be less expensive. Finally if your machine is still covered by AppleCare then give them a call and they can help you get it taken care of.

Imac superdrive scratching discs

My Imac late 2009 is scratching dvd's to shreds. I have no more warranty left. I have a couple of questions.
1. Do I take it to the apple store for repair
2. Does anyone know roughly how much it is going to be?
3. Does the apple store give me an estimate before repairing?

just came back from the Apple Store In Pointe Claire Montreal, my appointment was for 2pm, I was served at 2pm THAT WAS GREAT.
Now for the bad stuff. The Genius, was able to burn a cd and a 4.7 gig dvd without issue, no scratches. He said maybe I got a bad batch of discs (Verbatim DVD+R DL 8.5 gigs) and I should try to buy a new spindle first.
He believes the verbatim's are slightly thicker and it maybe the issue. He said he is going to order the replacement DVD drive for my Imac and call me when it comes in the total will be 187.95, I can decide AFTER I try a new batch of discs to see if the issue persists.
After I came out of the Apple Store I went to Best Buy and purchased a new spindle of 10 Verbatim DVD+R DL, I brought my Imac home fired it up tried to burn a disc and the same issue occurred. Scratches! on the disc.
Replace or not to Replace that is the question. I read many people have had the drive replaced and the same thing occurred. Any advice would be great, as I am unsure as what to do.

MAC MINI MATSHITA DVD-R UJ-845C
Mac mini 1.42GHz PowerPC G4 | 512 MB DDR SDRAM

Finder Burn - single folder containing many sub-folders totaling about 800Mbytes and approx. 4000 files.
Burn Speed Options : 4x(faster) : 2x : 1x(more reliable) - actual Finder media disc burn dialogue descriptions
[default selection is 4x(faster) ]
We choose 1x(more reliable) ..
Observations include .. no 8x speed media disc burn available from our little Mac mini Matshita DVD-R UJ-845C burner .. and .. as this is a DVD R .. we have time .. but no going back once burned .. and we want maximum systems compatibility .. you, dear reader, already know the drama we have previously experienced with Finder burns and older Apple iMac DV SE machine DVD drive (media disc burned) read compatibilities.
The total burn was a lengthy delay before the entire routine was completed including automatic verification.
OUTCOME
This disc did not verify correctly and is unreliable. Because this disc is unreliable, discard it and try again using a new, blank disc. (Error code ) 0x80020063
Total disc burned is almost 800Mbytes and about 4000 files.
Verification was not an available option for the burn .. a Finder burn .. meaning verification was apparently automatically included as an unseen 'yes' option at media disc burn execution time.
Examining the resulting Apple DVD R media disc burned .. we discover that things are good .. biggest single files (.dmg's at about 100Mbytes expanding to 350Mbytes - e.g. OS X 10.4.3 update) are able to be copied from the burned Apple DVD R media disc back to the Mac mini hard disk again and verify 100% when opened for installation. Encouraging. Better than anything previously experienced.

Into the Apple iMac ancient (500 MHz PowerPC G3 operating OS X 10.4.3 Tiger | 640MB SDRAM) and we are greeted with goodness .. same accessibility as the originating Mac mini machine .. satisfying.
And yes the 'problem' of multi-session burns is yet to come on the ancient iMac and if the response is any good as now .. it may not be a problem worthy of mention. At 800 Mbytes burn and 4.7 Gbytes capacity .. one could loosely forecast up to another 5 media disc burn sessions before the DVD R is full and complete.
XP MACHINE
And now into the PC machine for an XP looksee and again .. more goodness. Cross compatible files are fully accessible (an entire - own - website burned). Large files copy 100%. Better than before.
Two thumbs up for this disk and burn.
Verification failure remains a current mystery. Anyone ?
It is easy to figure how one may doubt one's media burning hardware is any good by now .. but the gathering volume of supporting entries at the relevant media burning and error message forums reveals that hardware is unlikely to be (entirely) at fault .. rather something else .. say firmware ?
Apple Media DVD R discs are manufactured in Japan (stated on the disc) and the quality difference and price premium are consistent with what others have written of the place of manufacture and the Apple media disc as well. Mostly positive.
Still .. we should like to have access to dependable RW discs from Apple too .. for reliable re-useability.
As for the subject of burn speed ...
Many forum readers are well aware of an ongoing and gradually escalating matter between Apple and this gentleman http://www.crc.id.au/page/2/ .. we have curiously followed the unfolding events to observe the outcome of the burn speed specification variation. As you know .. our Mac mini is rated at maximum DVD media disc burn 4x and fitted with a MATSHITA DVD-R UJ-845C which is a later edition than Mr H's UJ-835 .. however .. we are more curious to observe whether the final outcome will satisfy Mr H or not. Burn speed, primarily, and quality of burn, secondarily, on selected media by Mr H. Once the outcome is known and to Mr H's satisfaction .. then we may enquire about his satisfaction with burn quality at the chosen burn speed(s) by Mr H.
Here is an offline forum communication that we shared with another Mac mini user about disc media burn speed. As you may read .. he is entirely dissatisfied with the Mac mini media burn speed and isn't too keen on using the Apple disc burn media either ...
So...Have you found any dvd-r or +r media that burns reliably on the mini? (non apple media please).
I am completely disgusted with my new mini's pathetic superdrive that I paid way too much for.
I have purchased new & built from new parts several PC's that burn DVD after DVD on a wide variety of media reliably.

What SuperDrive description is fitted in your new mac mini ?
We seem to be staring into a gaping black hole of acknowledgement .. from anyone.
PC users, windows operating system software computers, appear to have an extreme edge .. when it comes to media disc burning. i.e. successful burns.
Re-reading that lengthy post .. which doesn't fully format as intended .. has me fully believing that less is more and small is beautiful (still). Future specific posts will probably follow as a matter of personal self-committment .. to persist until the solutions are fully to hand. For now .. may we refer to your mentioned post in our next planned post please ? Solidarity of negatory outcome experience is credibility.
Three forums have we frequented and participated to learn more about the black hole .. we know as SuperDrive media disc burning .. only you have provided any feedback whatsoever .. post reader numbers grow but answers are missing in action .. absent from class.
http://www.crc.id.au/page/2/
We have thought the SuperDrive matter you have referred to in your post was of no concern to us .. but now you have us thinking again .. although model numbers differ .. (ours is a later numerical reference) the concerns appear to be similar .. or largely about performance .. we shall also refer to this domain in our planned next post. Yes, we are aware of the matter .. from another forum .. but shall now supply the link for others to weigh and hopefully dish out their two cents worth .. where a consensus could mean we are also a part of this particular action. An ideal consensus would be firmware is unsuitable .. requires immediate update .. and in particular the quality of burn is consensually unacceptable .. action could follow.
We have progressed no further with burning experimentations .. and will be using Apple media before progressing with our findings reporting. For now, we are unable to add to your ease of mind .. frankly .. unless the burning media is made in Japan .. we doubt any burn verification success is to be had. And we cannot find any burning media made in Japan in our locale. Where is the Apple media made?
We have come to appreciate the SuperDrive is all about the firmware .. but have no new firmware to apply .. in fact .. our research to date shows that we have been unable to find the Matshita SuperDrive at all online and cannot confirm specifications .. neither could we locate the specifications at www.apple.com.au .. which is just plain odd.
A third look has provided ... from www.apple.com/macmini/specs.html ..
Storage
* One of the following optical drives:
o Slot-loading Combo drive (DVD-ROM/CD-RW): reads DVDs at up to 8x speed, writes CD-R discs at up to 24x speed, writes CD-RW discs at up to 16x speed, reads CDs at up to 24x speed
o Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed
Where were you able to establish your SuperDrive (burning) specifications ?
Writer's note : .. some things change .. and so have the Apple Mac mini SuperDrive burner specs changed .. since recording those detailed above. In fact .. they read like they maybe should have all along .. 8x DVD R media burn speed. DL is a bonus. Can anyone tell us what the drive designation is please ?
CRC says: ".. This limits burn speed to 4x for Mac Minis and 8x for Powerbooks.".
While speed matters .. and it does .. you appear to have exactly the same media disc burning problems that we are experiencing .. failed verification(s) .. and for us .. in short .. complete DVD-R media disc burned rejection from the Apple OS X.
Do we .. in actual fact .. have two separate operating challenges here .. speed of burn and quality of burn .. any burn ? Speed was not our first priority .. quality is .. now we figure that at any speed the burn quality is anywhere from dubious to coaster.
CRC says: ".. The UJ-835 that Apple use is firmware limited to suit various bits of hardware that they want to put together. The burner in the Mac Mini is the exact same model as the one in the PowerBooks. Apple load a 4x firmware on the Mac Mini, and an 8x firmware on the PowerBook drives.
My bet is that this is for marketting reasons only. ".

My parents have a mini and my has one of the PowerBooks. Confirmed the drives are Matsushita UJ-835. They have never had an issue burning DVDs. Confirmed it by burning DVDs last night on the wife’s 12″ PowerBook.
As far as updating the Firmware in your optical drives, no, you do not have to remove them from the machines to update their firmware. I’ve updated the firmware on my optical drives (for Region Free and/or speed gains) via the GUI in Mac OS X. One application that will do this is called DVRFlashX I believe. The key is then finding the firmware, which is platform agnostic.
BTW, removing the drive wouldn’t void the warranty on your Mac but messing with the firmware certainly will void the warranty on the drive.
Our primary concern remains SuperDrive media disc burn quality .. while you do appear to share the same concern as well as speed performance. Mr Haigh's only concern appears to be speed .. and here we may have missed any opportunity .. since the MATSHITA DVD-R UJ-845C
SuperDrive is a later designation and the speed performance specifications showing on the apple web-site are likely consistent with current performance capabilities of that SuperDrive and later .. including yours ?
Mr H may have indeed received marketing materials that promised 8x while actually receiving a 4x SuperDrive .. which only performs at 2x unless exceptional media disc(s) .. so he does have a legitimate claim concerning performance. Do we ?
What has us fully curious is whether he can burn quality media disc(s) with his new SuperDrive ..
(Update 24/12/2005 07:10pm (+11 GMT)
Well, it seems that Apple have decided to replace my hardware. I've started the proceedings yesterday and will hopefully get some news in the new year as to what they are going to replace. At the moment, I'm looking to send in the 12" Powerbook for a replacement, then see what changes in the mac mini side of things. I'm not going to accept the same DVD drive - as we all know the problems with the UJ-835. Stay tuned for more details as they come to hand.) .. http://superdrive.crc.id.au/
.. which would likely be the same as yours .. now that should prove an interesting outcome .. which he seems likely to voluntarily report and will be the essence of any enquiries from us in the near foreseeable future assuming Mr Haigh is forthcoming in his SuperDrive computing developments.
Mr Haigh may have begun to scratch the surface (so to speak) .. and find the more serious problem is that no matter how fast or slow the SuperDrive .. reliable media disc burns are a fantasy !
As yet no update .. almost three months .. could the delay by Apple could have something to do with the model identification of any replacement DVD burner .. if they use an UJ-845 .. then all **** could break loose as Apple users realise (such as we) they do have the same DVD burner and (in a Mac mini) are limited to 4x maximum speed DVD media disc burning performance .. so another designation may be required .. one that already delivers 8x DVD burns .. bit of a mess really .. and the latest Mac mini SuperDrive sports 8x DVD R media burn speed.
We are curious about you too, dear reader .. are you satisfied with your non Apple disc media burn quality ? We are able to openly admit that we are dissatisfied with our non Apple disc media burn output quality.
We are currently satisfied with the Apple DV R disc media burn quality. However at a price of premium dollars and an unexplained media burn verification failure message.
Burn speed, we nonchalantly confess, is not our greatest concern, and, for now, falls to a lower priority of importance with us.
For now the matter is at rest with us.
How about you ?
Yours Sincerely

PS. .. helping to explain the confusions surrounding the Mac mini SuperDrive is this extracted from ..
http://en.wikipedia.org/wiki/Mac_mini
October 2005–February 2006
Multiple reports exist that the Mac mini was quietly upgraded in October 2005 to 64 MiB VRAM, and either a 1.33 GHz (up from 1.25 GHz) or 1.5 GHz G4 (up from 1.42 GHz) processor, with 512 MiB of PC3200 RAM while underclocking it to PC2700. The 80 GB drive is currently a Seagate Momentus 5400.2 ST9808211A, which runs at 5400 RPM with an 8 MiB cache. The SuperDrive is a MATSHITA DVD-R UJ-845, which supports +R DL burning, and may also have unofficial support for DVD-RAM. Apple did not revise the official specifications on their web site. This may be to avoid issues with discounting or discontinuing of old stock.
Well .. whatever .. we use a MATSHITA DVD-R UJ-845C SuperDrive .. wouldn't that mean we have +R DL feature too ? .. probably not judging by the following explanations .. sort of .. and yes you could grab the mac_min.pdf service manual and do your own upgrading and overclocking as it pleases you .. try google for more info.

Mac Mini Part 11
January 9, 2006
Stealth Upgrade
Xxxxxx Xxxxxxxx
I recently received the SuperDrive Mac Mini that I ordered from Amazon the day after Christmas. To my delight, my Mini contains a 1.5 GHz PPC and 64MB of video RAM.
The SuperDrive is listed as a Panasonic UJ-845. According to Panasonic's web site this drive is supposed to allow DVD-RAM writing (and I assume reading). Has anyone attempted to use DVD-RAM discs with this drive under 10.4.3?
Xxxxxx Xxxx
I also have a new SuperDrive mini with the same specs, and note that the UJ-845 drive doesn't include DVD-RAM capability, though as Gordon notes the OEM Panasonic drive does. However, Panasonic's spec page is for the UJ-845-B drive, and I expect that the one in the mini is instead a special version of the UJ-845 that Panasonic made for Apple with DVD-RAM disabled. For some reason Apple doesn't seem to want to support DVD-RAM, which is a pity. I believe the drive will work with DVD-RAM discs, but treat them like DVD-RW, requiring complete erasure every time they're used, rather than allowing addition and subtraction of individual files, which is what makes DVD-RAM a great backup/exchange medium, especially for travelers.
My new PowerBook came with an Apple-labeled Panasonic UJ-825-C drive, which System Profiler saw as simply "UJ-825" and which didn't include DVD-RAM although Panasonic's specs showed it; I replaced it with an 825-B I got on eBay, which System Profiler sees as "845-S" and which now does DVD-RAM even without Patchburn. Note that the 825 is two generations earlier than the current 845/846 drive (whose new feature is DL burning); DVD-RAM has been available for a long time, but Apple has been using special versions of the drives without it.
How to exactly determine the capabilities of your drive: Insert a disc (any type, CD or DVD, but not a blank recordable disc that has to be formatted), open Disk Utility, and on the left side select the drive (not the disc in the drive), then look in the lower right side of the window where it says "Capabilities". You may have to widen the window to see the whole list, as it doesn't wrap for some reason. If it says "DVD-RAM" in the list, the drive should do DVD-RAM discs as they are meant to be used: like a 4GB floppy disk, they must be formatted once, then can be used as "random access media" (RAM). Doesn't matter what kind of disc you put in the drive; any type will make the drive appear in Disk Utility, which will then show its capabilities.
FOLLOWUP: I opened up the Mac Mini, and found the SuperDrive is an Apple label "UJ-845C", presumably a special version of the 845 with DVD-RAM disabled, unlike the UJ-845-B spec'd at the Panasonic site.
[MacInTouch]
We just received a middle-model Mac Mini - 80GB/512MB/AirPort+Bluetooth/Tiger - ordered from Amazon (currently $519.99 after rebate) and were pleased to find that it is one of Apple's "stealth" upgrades, where the label belies the actual specifications. Apple shows it as a 1.42GHz model, but it's actually running at 1.5 GHz, according to System Profiler.
It has a Seagate ST9808211A hard drive, which is a 5400-RPM model (better than the dog-slow 4200-RPM drives Apple started shipping sometime after the original Mini models debuted).
The optical drive is a Matsushita CW-8124, a Combo drive with 24X CD writing and reading and the ability to read DVD-R and DVD-RW, as well as DVD-ROM, at 8x.
System Profiler shows 64 MB of video RAM - double Apple's specified amount - for the "ATY,RV280" graphics card (ATI Radeon 9200) on an AGP bus, supporting display rotation and Quartz Extreme but not Core Image.
(For what it's worth, we found that we could not connect a Dell 1704FPT to the digital video port while an analog video cable was connected; after removing the analog cable, the Dell works beautifully with the Mini's DVI video. The Dell display also worked fine with analog video via the adapter included with the Mini.)
We also tried a WiebeTech Maxelerate hard drive enclosure but found it unpleasantly noisy, even in a special reduced-RPM version the company offers customers who raise the issue. By contrast, the miniStack we previously reviewed is virtually silent with the same hard drive inside.
Xxx Xxxxxxx
While this isn't the first time I've seen this type of 'error' from Apple, or other firms, this particular incident seems to have gone beyond the typical example, and I'm beginning to wonder if it is more than just an overlap in an otherwise complicated process.
I've done my share of OEM documentation, including manuals, labels and cartons. I know how hard it is to maintain reality in this regard. But in this case, it seems to me that the mismatch between the inside and the outside of the package has gone beyond the norm, and I'm wondering if someone along the line has simply decided to live with it, rather than deal with it up front. I can see this saving money...changes cost more than just the ink - it takes time and planning to overcome a spec change and cover all the bases.
I wouldn't be surprised if someone in a position to decide hasn't simply elected to run out the materials without implementing changes. After all, the customer gets more than they expect, which can be favorable publicity, and we all know the saying "any publicity is good, and good publicity is even better".
On the other hand, it can be a minefield to fess up. Once word gets out, customers start hand-picking the good from the better, taking the higraded units and leaving the rest as floatsom. Or they buy the downgrade for less, then return it shortly thereafter, demanding the up while refusing to pay more.
Let's just hope the sun keeps shining on this particular parade, and no one decides to claim fraud. All it would take is one competitor with a surplus of over-eager attorneys, and Apple would be forced to apologize for over-stuffing the golden goose.

We seem to be staring into a gaping black hole of acknowledgement .. from anyone.
PC users, windows operating system software computers, appear to have an extreme edge .. when it comes to media disc burning. i.e. successful burns.
Re-reading that lengthy post .. which doesn't fully format as intended .. has me fully believing that less is more and small is beautiful (still). Future specific posts will probably follow as a matter of personal self-committment .. to persist until the solutions are fully to hand. For now .. may we refer to your mentioned post in our next planned post please ? Solidarity of negatory outcome experience is credibility.
Three forums have we frequented and participated to learn more about the black hole .. we know as SuperDrive media disc burning .. only you have provided any feedback whatsoever .. post reader numbers grow but answers are missing in action .. absent from class.
http://www.crc.id.au/page/2/
We have thought the SuperDrive matter you have referred to in your post was of no concern to us .. but now you have us thinking again .. although model numbers differ .. (ours is a later numerical reference) the concerns appear to be similar .. or largely about performance .. we shall also refer to this domain in our planned next post. Yes, we are aware of the matter .. from another forum .. but shall now supply the link for others to weigh and hopefully dish out their two cents worth .. where a consensus could mean we are also a part of this particular action. An ideal consensus would be firmware is unsuitable .. requires immediate update .. and in particular the quality of burn is consensually unacceptable .. action could follow.
We have progressed no further with burning experimentations .. and will be using Apple media before progressing with our findings reporting. For now, we are unable to add to your ease of mind .. frankly .. unless the burning media is made in Japan .. we doubt any burn verification success is to be had. And we cannot find any burning media made in Japan in our locale. Where is the Apple media made?
We have come to appreciate the SuperDrive is all about the firmware .. but have no new firmware to apply .. in fact .. our research to date shows that we have been unable to find the Matshita SuperDrive at all online and cannot confirm specifications .. neither could we locate the specifications at www.apple.com.au .. which is just plain odd.
A third look has provided ... from www.apple.com/macmini/specs.html ..
Storage
* One of the following optical drives:
o Slot-loading Combo drive (DVD-ROM/CD-RW): reads DVDs at up to 8x speed, writes CD-R discs at up to 24x speed, writes CD-RW discs at up to 16x speed, reads CDs at up to 24x speed
o Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed
Where were you able to establish your SuperDrive (burning) specifications ?
Writer's note : .. some things change .. and so have the Apple Mac mini SuperDrive burner specs changed .. since recording those detailed above. In fact .. they read like they maybe should have all along .. 8x DVD R media burn speed. DL is a bonus. Can anyone tell us what the drive designation is please ?
CRC says: ".. This limits burn speed to 4x for Mac Minis and 8x for Powerbooks.".
While speed matters .. and it does .. you appear to have exactly the same media disc burning problems that we are experiencing .. failed verification(s) .. and for us .. in short .. complete DVD-R media disc burned rejection from the Apple OS X.
Do we .. in actual fact .. have two separate operating challenges here .. speed of burn and quality of burn .. any burn ? Speed was not our first priority .. quality is .. now we figure that at any speed the burn quality is anywhere from dubious to coaster.
CRC says: ".. The UJ-835 that Apple use is firmware limited to suit various bits of hardware that they want to put together. The burner in the Mac Mini is the exact same model as the one in the PowerBooks. Apple load a 4x firmware on the Mac Mini, and an 8x firmware on the PowerBook drives.
My bet is that this is for marketting reasons only. ".

My parents have a mini and my has one of the PowerBooks. Confirmed the drives are Matsushita UJ-835. They have never had an issue burning DVDs. Confirmed it by burning DVDs last night on the wife’s 12″ PowerBook.
As far as updating the Firmware in your optical drives, no, you do not have to remove them from the machines to update their firmware. I’ve updated the firmware on my optical drives (for Region Free and/or speed gains) via the GUI in Mac OS X. One application that will do this is called DVRFlashX I believe. The key is then finding the firmware, which is platform agnostic.
BTW, removing the drive wouldn’t void the warranty on your Mac but messing with the firmware certainly will void the warranty on the drive.
Our primary concern remains SuperDrive media disc burn quality .. while you do appear to share the same concern as well as speed performance. Mr Haigh's only concern appears to be speed .. and here we may have missed any opportunity .. since the MATSHITA DVD-R UJ-845C
SuperDrive is a later designation and the speed performance specifications showing on the apple web-site are likely consistent with current performance capabilities of that SuperDrive and later .. including yours ?
Mr H may have indeed received marketing materials that promised 8x while actually receiving a 4x SuperDrive .. which only performs at 2x unless exceptional media disc(s) .. so he does have a legitimate claim concerning performance. Do we ?
What has us fully curious is whether he can burn quality media disc(s) with his new SuperDrive ..

Well, it seems that Apple have decided to replace my hardware. I've started the proceedings yesterday and will hopefully get some news in the new year as to what they are going to replace. At the moment, I'm looking to send in the 12" Powerbook for a replacement, then see what changes in the mac mini side of things. I'm not going to accept the same DVD drive - as we all know the problems with the UJ-835. Stay tuned for more details as they come to hand.) .. http://superdrive.crc.id.au/
.. which would likely be the same as yours .. now that should prove an interesting outcome .. which he seems likely to voluntarily report and will be the essence of any enquiries from us in the near foreseeable future assuming Mr Haigh is forthcoming in his SuperDrive computing developments.
Mr Haigh may have begun to scratch the surface (so to speak) .. and find the more serious problem is that no matter how fast or slow the SuperDrive .. reliable media disc burns are a fantasy !
As yet no update .. almost three months .. could the delay by Apple could have something to do with the model identification of any replacement DVD burner .. if they use an UJ-845 .. then all **** could break loose as Apple users realise (such as we) they do have the same DVD burner and (in a Mac mini) are limited to 4x maximum speed DVD media disc burning performance .. so another designation may be required .. one that already delivers 8x DVD burns .. bit of a mess really .. and the latest Mac mini SuperDrive sports 8x DVD R media burn speed.
We are curious about you too, dear reader .. are you satisfied with your non Apple disc media burn quality ? We are able to openly admit that we are dissatisfied with our non Apple disc media burn output quality.
We are currently satisfied with the Apple DV R disc media burn quality. However at a price of premium dollars and an unexplained media burn verification failure message.
Burn speed, we nonchalantly confess, is not our greatest concern, and, for now, falls to a lower priority of importance with us.
For now the matter is at rest with us.
How about you ?
Yours Sincerely

PS. .. helping to explain the confusions surrounding the Mac mini SuperDrive is this extracted from ..
http://en.wikipedia.org/wiki/Mac_mini
October 2005–February 2006
Multiple reports exist that the Mac mini was quietly upgraded in October 2005 to 64 MiB VRAM, and either a 1.33 GHz (up from 1.25 GHz) or 1.5 GHz G4 (up from 1.42 GHz) processor, with 512 MiB of PC3200 RAM while underclocking it to PC2700. The 80 GB drive is currently a Seagate Momentus 5400.2 ST9808211A, which runs at 5400 RPM with an 8 MiB cache. The SuperDrive is a MATSHITA DVD-R UJ-845, which supports +R DL burning, and may also have unofficial support for DVD-RAM. Apple did not revise the official specifications on their web site. This may be to avoid issues with discounting or discontinuing of old stock.
Well .. whatever .. we use a MATSHITA DVD-R UJ-845C SuperDrive .. wouldn't that mean we have +R DL feature too ? .. probably not judging by the following explanations .. sort of .. and yes you could grab the mac_min.pdf service manual and do your own upgrading and overclocking as it pleases you .. try google for more info.

Mac Mini Part 11
January 9, 2006
Stealth Upgrade
Xxxxxx Xxxxxxxx
I recently received the SuperDrive Mac Mini that I ordered from Amazon the day after Christmas. To my delight, my Mini contains a 1.5 GHz PPC and 64MB of video RAM.
The SuperDrive is listed as a Panasonic UJ-845. According to Panasonic's web site this drive is supposed to allow DVD-RAM writing (and I assume reading). Has anyone attempted to use DVD-RAM discs with this drive under 10.4.3?
Xxxxxx Xxxx
I also have a new SuperDrive mini with the same specs, and note that the UJ-845 drive doesn't include DVD-RAM capability, though as Gordon notes the OEM Panasonic drive does. However, Panasonic's spec page is for the UJ-845-B drive, and I expect that the one in the mini is instead a special version of the UJ-845 that Panasonic made for Apple with DVD-RAM disabled. For some reason Apple doesn't seem to want to support DVD-RAM, which is a pity. I believe the drive will work with DVD-RAM discs, but treat them like DVD-RW, requiring complete erasure every time they're used, rather than allowing addition and subtraction of individual files, which is what makes DVD-RAM a great backup/exchange medium, especially for travelers.
My new PowerBook came with an Apple-labeled Panasonic UJ-825-C drive, which System Profiler saw as simply "UJ-825" and which didn't include DVD-RAM although Panasonic's specs showed it; I replaced it with an 825-B I got on eBay, which System Profiler sees as "845-S" and which now does DVD-RAM even without Patchburn. Note that the 825 is two generations earlier than the current 845/846 drive (whose new feature is DL burning); DVD-RAM has been available for a long time, but Apple has been using special versions of the drives without it.
How to exactly determine the capabilities of your drive: Insert a disc (any type, CD or DVD, but not a blank recordable disc that has to be formatted), open Disk Utility, and on the left side select the drive (not the disc in the drive), then look in the lower right side of the window where it says "Capabilities". You may have to widen the window to see the whole list, as it doesn't wrap for some reason. If it says "DVD-RAM" in the list, the drive should do DVD-RAM discs as they are meant to be used: like a 4GB floppy disk, they must be formatted once, then can be used as "random access media" (RAM). Doesn't matter what kind of disc you put in the drive; any type will make the drive appear in Disk Utility, which will then show its capabilities.
FOLLOWUP: I opened up the Mac Mini, and found the SuperDrive is an Apple label "UJ-845C", presumably a special version of the 845 with DVD-RAM disabled, unlike the UJ-845-B spec'd at the Panasonic site.
[MacInTouch]
We just received a middle-model Mac Mini - 80GB/512MB/AirPort+Bluetooth/Tiger - ordered from Amazon (currently $519.99 after rebate) and were pleased to find that it is one of Apple's "stealth" upgrades, where the label belies the actual specifications. Apple shows it as a 1.42GHz model, but it's actually running at 1.5 GHz, according to System Profiler.
It has a Seagate ST9808211A hard drive, which is a 5400-RPM model (better than the dog-slow 4200-RPM drives Apple started shipping sometime after the original Mini models debuted).
The optical drive is a Matsushita CW-8124, a Combo drive with 24X CD writing and reading and the ability to read DVD-R and DVD-RW, as well as DVD-ROM, at 8x.
System Profiler shows 64 MB of video RAM - double Apple's specified amount - for the "ATY,RV280" graphics card (ATI Radeon 9200) on an AGP bus, supporting display rotation and Quartz Extreme but not Core Image.
(For what it's worth, we found that we could not connect a Dell 1704FPT to the digital video port while an analog video cable was connected; after removing the analog cable, the Dell works beautifully with the Mini's DVI video. The Dell display also worked fine with analog video via the adapter included with the Mini.)
We also tried a WiebeTech Maxelerate hard drive enclosure but found it unpleasantly noisy, even in a special reduced-RPM version the company offers customers who raise the issue. By contrast, the miniStack we previously reviewed is virtually silent with the same hard drive inside.
Xxx Xxxxxxx
While this isn't the first time I've seen this type of 'error' from Apple, or other firms, this particular incident seems to have gone beyond the typical example, and I'm beginning to wonder if it is more than just an overlap in an otherwise complicated process.
I've done my share of OEM documentation, including manuals, labels and cartons. I know how hard it is to maintain reality in this regard. But in this case, it seems to me that the mismatch between the inside and the outside of the package has gone beyond the norm, and I'm wondering if someone along the line has simply decided to live with it, rather than deal with it up front. I can see this saving money...changes cost more than just the ink - it takes time and planning to overcome a spec change and cover all the bases.
I wouldn't be surprised if someone in a position to decide hasn't simply elected to run out the materials without implementing changes. After all, the customer gets more than they expect, which can be favorable publicity, and we all know the saying "any publicity is good, and good publicity is even better".
On the other hand, it can be a minefield to fess up. Once word gets out, customers start hand-picking the good from the better, taking the higraded units and leaving the rest as floatsom. Or they buy the downgrade for less, then return it shortly thereafter, demanding the up while refusing to pay more.
Let's just hope the sun keeps shining on this particular parade, and no one decides to claim fraud. All it would take is one competitor with a surplus of over-eager attorneys, and Apple would be forced to apologize for over-stuffing the golden goose.

Mac OS X - Scratches Discs!

Is anyone else having this problem? My new Mac OS X - desktop - is scratching discs. It is not how I pull the discs out. I am very careful. Apple has already replaced the superdrive twice now! And it is still scratching! The scratches are circular and obviously happen as the disc is spinning in the drive. Multiple scratches happen nearly every time I put a disc in the machine. What is going on?

Hi c2zion: If the main reason for your wanting X11, is to install Open Office, another very good option is Neo Office. It is very similar to Open Office, and doesn't require X11. It is available here: http://www.neooffice.org/neojava/en/download.php

How do I stop my macbook telling me scratch discs are full

I have reduced applications photos email etc from my laptop but I am being told 1. Start up discs are full and 2. Scratch discs are full what exactly does this mean. Would more memory help if so what type. The macbook is 2008 2.4 core 2 Duo, 2GB 667 MHz DDR SDRAM. Thanks I know this is a daft question for most people.

Yeah, same problem here, same sentiment! it sure feels like harassment. no solution works (even the absurd ones). makes me regret the update :s

Using an external hard drive (HD), on a network, as a scratch disc?

I am weighing my options on creating a wireless network around an external HD. My macbook pro is getting full and I am going to do a spring cleaning and get everything in order. I pretty much know how I want to do it but I am wondering if I can use an external hard drive as a scratch disc, wirelessly?
Thanks in advance,

How in the world can I select my external hard drive as a scratch disc for video? Please skip the obvious, like 'is it plugged in?'

At wit's end trying to select my external hard drive to load video on. Time Machine backed stuff up on it so the computer knows it's there but it won't show anywhere else, iMovie or FCE4.

Hi Eric and thanx for the fast response. I've had very little time to piddle around with this iMac and fce4 since I got it a few years back but I DO remember seeing an option back then--when capturing video from the camera--to choose some other scratch disc. Some time after buying and plugging in the ext. drive I clicked on Time Machine (not even knowing what it was--some window popped up and it looked good). I wonder if turning on Time Mach has locked me out of the ext. drive. It doesn't show up ANYWHERE ANYTIME now, not under system pref., user pref. in fce4 or iMovie or anything else EXCEPT when I click on Time Machine it does tell me I've 2.97 terrabytes of space (which has to be the ext. drive; the iMac has 500 gb). I'm thinking of uninstalling and reinstalling fce4 and starting over.

Scratch Disc Questions using Firewire External Drive & Imac

Hello. I've read through the existing questions regarding scratch disc and Photoshop, yet can't seem to find an answer to my questions. I would greatly appreciate any tips/advice. Here is my setup and situation:
I am running an iMac with a 2.16 intel core 2 duo processor, 3 GB memory, and running OS X version 10.6.4. I am currently using versions cs3 and cs4 of Photoshop, but plan to upgrade to cs5 soon.
The problem I am having is when running Photoshop, my computer becomes very slow. After reading about possible reasons, I came across a couple of sources (including Adobe themeselves) mentioning that the scratch disc should be a designated drive seperate from the drive containing the operating system. Since I am using an iMac that only allows for one internal drive, my only apparent option seems to be an external drive.
Many people say don't use an external drive, but if you are going to; use an eSATA or firewire. The imac does have firewire 800 capabilities. Should I consider this?
Now I'm wondering if it's a bad idea to purchase a macbook for my next computer (what I wanted to do) because it will also only have one drive, not allowing for a seperate drive for the scratch disc. Any thoughts? I've read around the net but haven't found any definitive answers.

Designer,
Photoshop benefits greatly from having a scratch disk on a separate physical drive, not on the boot disk or on another partition of the boot disk. It's almost not worth connecting via Firewire 400 because the transfer limitations don't allow much performance improvement. But using a Firewire 800 connection gives excellent performance.
Running Photoshop on a one-drive machine is a little frustrating due to the performance hit without the separate scratch drive.

I have PSE-12 on Mac. Got message "scratch disc full" tried changing drive to backup disc. Now PSE-12 will not open to allow me to go back to original drive. What can I do?

Using PSE-12 on my Mac and got the message 'scratch disc full' I have backup disc attached to computer and tried making this the number 1 disc. I now can't get PSE-12 to open so that I can get back and reverse the order of these discs. What can I do?

Go to your username>library>preferences and delete:
com.adobe.PhotoshopElements.plist
Adobe Photoshop Elements 12 paths
Adobe Photoshop Elemetns 12 settings
and any lockfiles with the same names. That library is hidden in 10.7 and up. To see it, click the Go menu in the finder and hold down the Option key and it will appear below the little house for your user account. While you're in there go to the saved application states folder and delete any for PSE.

How to determine the scratch disc size?

hello,
once i was reading an adobe pdf "How to get better performance in photoshop cs5" - that was in 2009 or 2010, and may be outdated, but there was a calculation method
to determine the size of a scratch disc. (similar calculation see below, if i can remember right)
i am asking myself, how can i determine the correct size of an external SSD-scratch disc, only used by photoshop (completely empty):
should i buy a 128GB or 256GB or 512GB SSD which is only reserved for photoshop?
basic question 1 : i guess i should avoid to set the internal SSD as photoshop scratch disc, as it slows down everything?
basic question 2 : in sense of maximum performance: better buy an external USB3.0 or thunderbolt SSD? will photoshop really use the extra thunderbolt speed when swapping data?
secondary question:
can i calculate the size regarding my daily working habits?
i am mainly working like this:
- with my imac 27" late 2013 with 32GB RAM and 256 GB internal pci-e SSD (800 MB/sec), which will stay always half empty for performance reasons.
- OSX 10.8 mountain lion and 10.9 mavericks soon
- photoshop cs5, cs6 and cc (always without extended)
- 8bit and 16bit mode
- only RGB
- with latest phocus/Hasselblad and canon RAW Files which produce a basic .psb document at ...
- 10.000 x 7000 px at 300dpi
- with average 10 - 40 main image layers and 20-50 adjustement layers (try to reduce that in 16bit)
- .psb file is 2-20 GB big (file in finder)
- 16bit file compression is off, when saving .psb files (faster handling)
- set photoshop to 70% ram usage (from 32GB RAM)
i wonder how to calculate ?
for example:
10.000 x 7000 px at 300dpi needs for one image layer at 16bit: 2GB RAM in photoshop cs6 or cc (just as a number), this may be wrong
so lets take 2GB RAM and multiply with 10 image layers in my .psb file (16bit) = 20 GB RAM, and multiply with 20 adjustment layers (guess they need less ram, for one lets say 500MB) = 20GB + 10GB = this 16bit .psb layer file would need 30GB RAM, so when i have 32GB in my imac, i set cs6 or cc to 70% ram usage, it misses at least round 8-10GB RAM > can i guess that photoshop would swap these 8GB onto my scratch disc? or do i miss something important in my thinking?
tricky thinking
thanks for help

The rule of thumb I follow says to figure on 50 to 100 times the size of your largest file ever multiplied by the number of files you have open. I have seen the scratch file exceed 300 GB once, an admittedly rare occurrence, but it often exceeds 200 GB when stitching large panoramas and the like.
As an example—and stressing that I'm aware that others have even more scratch space than I do—I keep two dedicated, physically separate hard drives as my primary and secondary Photoshop scratch disks and a lot of GB free on my boot drive for the OS. I also have 16 GB of RAM installed.
Additionally, if you only have a single HD, i.e. your boot drive, you'd need it to be large enough to accommodate both the swap files of the OS as well as Photoshop's scratch.
- i dont use HDD anymore only SSDs, both internal and external
- i set history state to only 5 or 6, to improve performance
- i set cache size to 4 and tiles to "big and flat" with 1028kb (there is no "big and much layers" option)
- is this still the rule of thumb? i read it in 2009 , too, guess it was outdated, as cs6 and cc have improved codes in terms of performance?
- if you say "50 to 100 times the size of your largest file ever multiplied by the number of files you have open.":
i will not open more than one document at same time to prevent performance lags, so lets calc like: dokument size in finder (you mean in finder or doc. size shown in photoshop?) = e.g. 5GB x 100 = 500GB, so my external scratch disc SSD, i would buy now, should be at least 500GB, USB 3.0 or thunderbolt ... maybe better thunderbolt, yes? with usb 3.0 i could gain 300MB/sec if thats enough for photoshop?
thanks

What is a Scratch disc?

Hi, My discs (80+120gb) are almost full, I sought (and gained) info on the expanding your Mac forum and noticed a thread that referred to using a disc as a "scratch disc" for Photoshop, I use Photoshop a lot and would like to know what scratch disc means and how one makes a Photoshop scratch disc.
I am about to add a 500gb external FW HD so will have a disc spare to "free up" Would making one of them a scatch disc help Photoshops perfomance?
I can dedicate the 120gb to Photoshop as the 80gb contains the operating sysyem.
I am not the most computer literate person so easy English responses would be appreciated.
Thanks in advance.

Hi
The following article, courtesy of MacGurus, contains some useful information on improving Photoshop performance, although it's a little techy in places:
http://homepage.mac.com/boots911/.Public/PhotoshopAccelerationBasics2.3.pdf
Just be aware that if both discs (80GB and 120GB) are connected to the same ribbon cable (as master and slave), they have to take turns sharing the ATA bus. Consequently if the Photoshop application is on one and the other is being used as the scratch disc, performance may not be optimal (although may still be better than at present).

How to Reformat the hard drive I use to edit with..."scratch disc"

Today when I turned on my computer I got a strange message on the screen that basically said I need to back up one of my drives and format it asap. It also said the computer couldn't repair it.
This is the HD I use to edit with as my scratch disc with Final Cut Pro.
I am in the process of backing my files up now. One thing I noticed was that some of my files I don't need anymore and wanted to trash them but it won't allow me to trash files! I get an error message when I drag the file to the trash. So I am going to have to back everything up and I guess will have to erase the disc.
I never reformatted a disc before so if anyone knows what I need to do that would be great since this is the drive I used to edit with.
Thanks.
Message was edited by: DVX100Shooter

To reformat a hard drive, launch Disk Utilities (in the Applications->Utilities folder) and click on the Erase tab. Select the drive you want to reformat then choose "Mac OS Extended" ... give the volume a name and click on the Erase button.
Once the drive is reformatted, open FCP and assign it as the scratch disk.
However, the drive may be suffering from other problems that reformatting won't fix.

Suggestion For An External Scratch Disc needed

I have recently learned that I had my scratch disc set up incorrectly to the same internal SSD in the Mac Book Pro. I assume that to keep the maximum transfer speed I need and external HDD or SSD with FireWire 800 instead of USB. I have found a few of those but they are much larger than what I need in GB and physical size.
I need something portable and reliable since I do most of the work on the road.
Thanks for your suggestions.

Have you considered a G-Drive mobile or G-Drive mini SSD? Both are bus-powered.
If you're ok using AC power, look at the G-Drive mini.
These are very nice units - small, reliable, good reputation.
FireWire (or eSATA if you have a MBP with an ExpressCard slot) is the way to go. USB generally cannot keep up with the sustained throughput required for video.

How far should SuperDrive eject discs?

How far does your SuperDrive eject discs?
The one on my MBP Core 2 Duo 17" 2.33 GHz ejects recordable discs only about 1-3/8 in, which makes it impossible to remove them without touching the top or bottom surface. My newer MBP Core 2 Duo 17" 3.06 GHz ejects them much farther (about halfway), so they can be handled by the edges instead.
The problem doesn't occur with commercially pressed installation discs, only with discs I use to record on (Taiyo Yuden 8X DVD+R, Verbatim 8X DVD-R and Taiyo-Yuden 8X CD-R).
This is the second replacement of the drive from AppleCare with the same problem. (At least I think they replaced it a second time. The service record said, "Doesn't eject media" instead of "Doesn't fully eject media," so maybe they tested it and thought it was fine.)
Is this normal behavior? Anyone else seeing this?
Thank you,
David

My MBP 15" doesn't eject very far, but a little more than what your's does (I'd say around 2"). It does ok for me, though.
Do you notice any difference between commercially recorded discs and recordable ones?
