Powerbook Superdrive specs... Matshita UJ-846

Does someone know off the top of their head where on Apple's site I can find what the speeds and what media this drive supports? Specifically, if I need DVD+ or - for dual layer dvd burning.
Best buy has an instant rebate for Verbatim 20 pk DVD+R DL for $40.00, reg $60.
I remember looong ago, the superdrives only burned DVD-R's, and this is my first newer drive, so I could use a bit of help.
Thanks,
Mike

hello everybody
I have just burned 5 DVD+R double layer VERBATIM (2.4x certified 240) with special success
files are image disc (.dmg), 7.4GO
my DVD is matshita UJ 846 FAAG / MMC-3
It was with roxio toast titanium 5.2 (4disc) and with IDVD 5.01 (1 disc)
with roxio I have tried with different speeds (x2, X4, X8..)
always the same error message at the very end of the burning (roughtly 40minutes) "error /sense key =illegal request / sencecode=0x72,0x04 / empty or partially written reserved track / failure during burning the lead in or lead out"
with IDVD, I have tried to burned directly
it has crashed the apps just at the end !!
The most fabulous is that in both cases all DVDs function on my computer but not on my dvd player connected to TV. Whatever I do not feel comfortable with these incredible error messages
Can you help ?
best regards

PowerBook Superdrive Replacement

I replaced my 1.25 G4 PowerBook Superdrive (using an Apple reseller's shop) with a Pioneer - DVR-K04 8X Dual-Layer burner and was disappointed to discover that the burner will not do much greater than 2X and both Disk Utility and Toast reject the Fuji Dual-Layer blanks that I insert into the DVD slot.
Elsewhere on this board I have read about the higher speed (8X) being more or less an illusion because the drive will only burn 8X near the end of the burning process, however, the failure to recognize a dual-layer dvd blank puzzles me. Would that be because the original Superdrive was not capable of dual-layer, so that the PowerBook firmware (or whatever) still behaves as if the original drive were installed? If so, is there a workaround?

There is nothing on Pioneer's website about the DVR-K04 that I can find.

MATSHITA UJ-846 version FA0G

Hi. I;m getting trouble trying DL +R disk burning. My iMac has an MATSHITA UJ-846 version FA0G is this the lastest version for my drive ? if not, where can I get the lastest firmware ? Please, my finalcut original disks needs an urgent backup !!!

Yes it is thelast firmware. Mine has stopped being able to burn for a year now, it still reads cd & dvd but no burn (always error). I tried to clean with special cleaning disk (dry) so I went finally for an external burner see my old post http://discussions.apple.com/thread.jspa?threadID=1927719&tstart=0
So try zapping the PRAM maybe and then clean and if not get it replaced (under warranty) or go for external or...
Good luck in any case!

Post if successful with 8X DVD-R burns on MATSHITA UJ-846

Please post the brand of media used if you have had success burning a DVD-R at 8X on the MATSHITA UJ-846.

I am sorry to seem short, here but from the code you
gave the Media you are talking about is FINE. Read
the link on Quality.
I did read the link, but all I can tell from it is that Verbatim is in the top tier. I have no way to tell what media code the one that I am buying has BEFORE I buy it. That free application to check it after I buy it does not work for me. All I can tell from that link are what are the top tier media codes and the brands that use them. Yet if they outsource, then they could also be using inferior media, I gather.
IF THE CODE MATCHES IT DOESN"T MATTER WHERE YOU BUY
IT>
I understand that, but that is not my question. I don't know the media code if the retailer does not list it.
SuperMediaStore gives the code. Great! However, Buy.com doesn't, but it is the same product #.
My question is if the media codes can be different for the same product?
In other words could verbatim supply supermediastore with a batch of 16X (95102) with a great media code, yet supply the same product to buy.com with a inferior media code.
Do you know if Verbatim supplies different resellers with different levels of quality for the same product?
Far right in the link shows those media's
outsourced.
There are literally dozens of different Media out on
the market for you to buy. I say upwards of 60% of
all problems attributed to different errors while
burning is from POOR QUALITY MEDIA.
Most users will not take the time to do a little
research before they just go out and buy media not
knowing there is a big difference.
Don
I did all the research you recommended. Went out and bought some Vertatim 16 X product #95101 because Vertbatim is recommended on that site. I have no idea what the media code is for this particular one. I couldn't find it anywhere, and I still don't know if Verbatim uses different media codes for the SAME product.
Unfortunately, The DVD that I burnt was unable to be verified and disk utility said it was unreadable. I was backing up files.
This is very frustrating. I did hours of research only to come up with failure. I am going to try and return these. But, I need to repeat my unanswered question. Please listen to the question below and answer if accordingly if you know the answer.
If supermedia has Verbatim 16X DVD-R Media 100 pack (95102) listed as Media code: MCC03RG20, does that mean that the 16X DVD-R Media (95102) 100 pack sold by buy.com or others also have the same media code?
I apologize if I sound repetitive, but I feel horrible at this point.

IBook/Powerbook superdrive used for macbook pro replacement part?

Can I use a superdrive from an ibook or powerbook as a replacement part for my macbook pro?

I doubt the iBook drives would fit as Apple tended to use slightly larger drives but out of an Aluminium PowerBook you might have some luck.

Need Superdrive spec

I have the last version of eMac ever sold, the 1.42 ghz Superdrive. I cant tell what speeds I can burn DVD's and CD's at. The spec sheet for this particular model is missing from the Apple web site. Does anyone know the speed of this superdrive?
thanks.

Hey Ratty Mouse!
You're eMac has an 8x Double-Layer SuperDrive. Your CD burns at 32x and reads them at 32x (I think). I'm not sure of the DVD+R, DVD-RW, and DVD+rw. The 8x speed is DVD-R. Hope this helps.

Understanding PowerBook battery specs

Hi all,
I have a PowerBook G4 (15", 1.67ghz) and just purchased a new battery because my old one was draining in about 30 minutes (and I've done one calibration run on the new battery). Here are the relevant specs on the new battery from MiniBatteryLogger:
Max Capacity: 4240 (me), 4800 (best), 3242 (average), 409 (worst)
Original Capacity: 5200 (me), 5200 (best), 4422 (average), 4200 (worst)
My questions are these:
1) I see that a Max Capacity of 4240 is about average for reported statistics, while the best is 4800. Should I expect something like 4800 for a brand-new battery?
2) What exactly does "original capacity" mean? And how could the max capacity already be so distant from the original capacity?
Thanks much!
Cheers,
John

I'm not sure about MiniBatteryLogger's data, as I've never used it. But, your PB's battery is a 50 W-hr battery, meaning the 'original capacity' is 4630 mAh. That value is calculated based by dividing the power (50000 mWh) by the voltage (10.8V) = 4630 mAh. Actual values of new batteries will vary. The other factor is time - once made, lithium-based batteries are good for 400-500 charge cycles or 3-4 years, whichever comes first. So, depending on how long before your purchase your battery was produced, the max capacity it can currently hold may be less than that of a newly-made battery. I would expect that PB batteries are not ordered too often, so they sit on the shelf for a while (even at Apple, but especially at 3rd party sellers / eBay sellers).
(Hope this helps - I actually followed you here from the MBP forums. )

Booting XServe from PowerBook Superdrive?

Hello,
I need to upgrade my Gen2 G4 XServe from 10.2.8 to 10.4. My XServe does not have the SuperDrive option and the OS disks are only available on DVD now. They completely phased out the CD media for Tiger. So, I'd like to try to boot my XServe to the SuperDrive in my G4 PowerBook in order to install Tiger.
Obviously this would not be a supported method of upgrading, but does anyoneh have any input or experience trying this? If I can't get it working with the SuperDrive in my PB, I will just have to buy an external DVD-ROM.
Thanks.

Hi
I have been reading this with interest as I am having trouble upgrading my slotload G4 X Serve 1.333Ghz to OSX Server 10.4 Tiger.
Basically, the slotload CD drive simply spits out all disks offered to it. I tried linking up an external CD drive via Firewire and everything progresses well but throws up an error as it is about to start actually installing the software.
So... I followed the method you outline here and:
1. Once restarted in Target Disk mode and attached via Firewire to my PowerBook G4 17inch the server appears as a disk on the PowerBook desktop just as it should.
2. I insert the X Server 10.4 updater DVD into the Powerbook and start the install.
3. This triggers a restart from the DVD (as I would expect) BUT everytime it falls over part way through this during the first grey screen with the Apple logo on it. The clock graphic spins as normal at first but then just stops part way through the process never to start again. I have tried this on both my 17inch and 15inch PowerBooks and the same thing happens.
Any ideas?
Any thoughts you have would be much appreciated

Matshita UJ-846 burning speeds

I've just a got a PowerBook G.4 1.67 GHz Dual Layer Super Drive and it is a Matshita UJ-486 with firmware FAAG
and as I understand it burns DVD-R at 8x and DVD-RW at 4x but when I insert both DVD-RW or DVD-R it says in Toast
that it burn at 2x maximum, is it the media I'm using or the information I have about this drive is wrong?
Thanks for any advice

The information you have about the drive is correct. First of all, what does the media say for write speeds? If it is 8x or 16x DVD-R, it should be writable at 8x.
How to really find what is going on is to insert a blank disc and let finder show it as essentially a burn folder (but with the DVD icon). Drag any file onto that disc icon, then double click the icon to open the burn folder. Select "Burn Disc..." from the Finder's File menu and you will get a pop-up there which will have a speed setting set for the highest burn speed supported by the drive and the media (should be 8x or the media speed if it is lower for a DVD-R or DVD+R). You can then cancel that dialog and eject the disc.
If Toast still only wants to burn a higher speed disc at 2x, then that is a Toast issue, or at least is certainly looks like a Toast issue.

IMac - Matshita UJ-846 Problems...??!?!?

Hallo!
Why can't i enable in Windows XP DMA mode? There is allways PIO ONLY...
Tnx!

If you guys did a search on the optical drives you'll discover that they have a rather extensive
history for failure. the failing optical drive process starts off rather slowly and worsens over time.
You could replace the internal optical drive but rather than performing surgery on your Imac
you would be better off going with an external optical drive.
If your IMac is still under warranty you can have it replace but I would still pick up an external
as well, I have read a couple of threads where even after having the internal replace the same issue
happened yet again.
I ordered a LaCie that does rather well.
http://www.amazon.com/gp/product/B001P5C9S0/ref=oss_product
I did however discover a couple of minor issues with my LaCie...
1) When the mounts a disc , for some reason the mechanical ejection button
on the face of the enclosure is disabled. This is not a major issue right click and eject or, drag the
icon into the trash
2) if you are wanting to lightscribe be sure to go to the LaCie website and download the latest
lightscribe app, the one that came with mine was out of date and did not work in Mac OSX 10.6
3) My lightscribed DVD's had a problem , the images where filled with rings from the center of the
disc out, I have discovered this is due to calibration , Amazon has shipped me a new Lacie that
I have sitting in a box next to me, I have not had a chance to test out the new unit yet.
You may also look at OWC's optical drives

Either way make sure that you go with an optical drive with Firewire.

UJ-846 Superdrive unable to burn DVD+R

Hello,
It seems that I can't burn anything on any DVD+R with my superdrive (ref. UJ-846). I've tried with iDVD (initially I wanted to burn one of my home-made movie on DVD), Disc Burner, DiscBlaze, Dragon Burn. Each time, the answer is the same : media is not writable. Is it normal for a "Superdrive" advertised as "Universal"?
Is there a way to solve this issue, for the moment I don't have any other media within reach and anyway, not to be able to burn a DVD+R is like not to be able to burn anything...

More info after some additional testing:
Burned a few DVDs using the internal UJ-846 and Pioneer DVR-109 (in a firewire case). The source image was a Tiger DVD (from an earlier Mac). I used Burnz and Disk Utility to burn two DVD+R's (HP brand) in the DVR-109 and Toast and Disk Utility to burn the same brand discs (and a DVD+RW) in the UJ-846.
In the case of the DVD+RW, I received the message that it could not calibrate the device to the media (both in Toast and Disk Utility).
From the DVR-109 burns, my old G3 iBook spit out the resulting discs as unreadable. The iMac (UJ-846) did read the discs but took about 30 seconds from the time of disc insertion until the window showing the Installer appeared completely. The DVR-109 displayed this window 16 seconds after insertion.
I then burned (using Toast) a data DVD using the same DVD+R media. This disc was burned as "Mac & PC" hybrid. The contents of the disc were folders full of audio files. Again, the G3 iBook refused to read the disc while the UJ-846 took about twice as long as the DVR-109 to mount and open the disc.
Finally, I burned (using the DVR-109) a Verbatim DVD-R "white-top" printable (8X, pn94654, hub printable, no stacking ring) using the Tiger image file as the source. The resulting DVD was not only was readable in the old G3 iBook but booted it, as well.
I should note that these discs, when burned with my G5's internal burner (DVR-117 which, I believe, is the DVR-110 but with Apple firmware) would work fine for data (and boot discs) but never produced a video DVD that would play in my set-top box.
Now, just to be a bit more thorough, I dug up some DVD+R's that I've burned over the past few years. Sonuvagun! Not one of them can be read by the G3 iBook's optical drive. So it's apparent that the old drive just doesn't like +R of any brand (Ridata, HP, JVC).
Okay, so what have we (I) learned from all this (if anything)?
It is tempting to say that the results with the old G3 iBook might be ignored because it is, after all, one of the first (500MHz) units produced and everything is much more compatible these days. However, shouldn't a burned DVD (of either the + or - persuasion) be seen as simply a DVD by the Mac once it's been burned? My Intel iMac shows a "+R" or "-R" as part of the disc's icon yet these are =burned= discs. Perhaps I do not remembers when this behavior had changed but I recall that the "+" or "-" ID was only on discs that had yet to be burned; subsequent to burning, this ID was dropped. (or so I recall...)
Could it be that the "+R" compatibility claims are overstated? But what of the "+RW" disc that gave the "can't calibrate..." error? Should I chalk it up simply to media incompatibility? I have some "+RW" media (HP brand, identified by Toast as "PHILIPS.041."); testing that media results in a successful erase and burn/verify using the UJ-846; no "calibrate..." error as experienced with the Memorex +RW's. Toast sees the disc as a 4X and offers to burn it at that speed but it is really burning at 2X based upon the slow speed of the countdown in Toast's window.
I remember reading something about "book-type" when I used to burn with a PC; perhaps that's an issue? Or maybe that's just a red herring.
In any case, I'll have to do some more testing with a few more older Macs to see if they can read the older DVD+R & +RW I already have and any new ones I burn with the U-846 and DVR_109 using Intel OSX in my iMac.
Comments and suggestions always welcome.

12" G4/1.33 Superdrive - does it read DVD+R disks?

Hi all,
Quick check on the specs, which strangley I can't find anywhere on the web!
I have an Aluminum G4/1.33 12" with Superdrive (model Matshita UJ-825) and wanted to find out if it reads DVD+R disks. I was looking at a DVD Recorder from Philips for the TV that uses DVD+R and +RW disks, and wanted to know if movies and TV shows I burn with the Philips would be readable on my powerbook?
Thanks.
Chris

I have the same powerbook model as yours and I've tested three DVD burners with it. My Panasonic burner burns both + and - dvd's and the powerbook reads both fine. My brother-in-law has an iLo +R burner and it reads his as well. I also tested another model but I can't remember what it was(I know it wasn't a Phillips) but it only burned +R and the powerbook did not like those at all. I have not tried any RW's so I can't give an answer for those. By the way, I love my Panasonic burner, it is awesome because it burns everything +, -, R, RW. I hope this helps a little.

SuperDrive ejecting blank DVDs without mounting

My SuperDrive no longer reads blank DVDs, and just ejects them after a few seconds of spinning...
Specs: MATSHITA DVD-R UJ-857E; Firmware: ZA0E...
The DVD does not remain in the drive long enough to try anything with Disk Utility...
Anyone got a solution that does not involve replacing the drive or re-installing Leopard?

Again,
i have the same problem as detailed here with DVD -Rs being ejected, this time with a G5 iMac.
The drive 'spec' is:
MATSHITADVD-R UJ-846:
Model: MATSHITADVD-R UJ-846
Revision: FA0G
Serial Number:
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
Low Power Polling: Yes
I don't think I've seen any real solution to the problem, other than a full reinstall. However, presumably that just puts the OS back to a previous version which will get over-written with the next automatic update.

DVD Quicktime movie won't playback properly on G4 Powerbook

After authoring a movie in imovie hd and saving it as a dv Quicktime file and burning it to a dvd on my G4 Powerbook, the dvd freezes on the first couple of frames and just stutters forward. However, when I play the same dvd on my desktop imac G5 with identical software, the dvd plays back just fine. Any suggestions? I've tried discussions with Quicktime people with no results. The dvd drives on both computers are virtually identical, softwares identical...the only real difference is one is a G4 and one is a G5. Could that make that big a difference?

Tried reinstalling Quicktime and it didn't make a difference. maybe the problem isn't with Quicktime at all. I tried burning a dvd with the same Quicktime DV files on my imac, thinking it might be the superdrive in my laptop. the dvd plays back fine on the imac, but stutters and stops on the laptop. I can't believe it's just the difference between the G4 and G5 or the difference between the Matshita DVD-R UJ-816 in the powerbook or the Matshita DVD-R UJ 825 in the imac.
Anyone out there have any other suggestions? Some articles I've been reading lately suggest that it may be the media and that the two dvd drives respond differently to the type of DVDs I've been using (Maxell DVD-R 8x). Maybe I should try TDK or Apple?

Can the UJ-875 replace a UJ-846?

Has anyone replaced the Matshita UJ-846 with the UJ-875? (and got good results!)
I'm one of the thousands frustrated owners of a "UJ-846 that doesn't read disks anymore".
Thanks a lot in advance.

What I need to know is if there´s any physical spec that would make this drive (UJ-875) not to work on intel iMacs?
Please, help.
