Superdrive no longer recognizes Prodisc CD-Rs

I have a Matshita DVD-R superdrive (UJ-845C; DPP9) and used to be able to burn 1X-48X CD-R 80min/700MB Silver discs by Prodisc (SKU: CDR80COLOR/BLK).
However, still within the same lot of discs that once used to work perfectly fine, the drive can now no longer burn them (at any speed or configuration).
E.g., an iTunes error reads that the device failed to calibrate the laser power level for this media, and Roxio Toast reports a MEDIUM ERROR Sense Key with Code 0x73, 0x3, while Burn Disc reports Error 0x8002006D.
My DiscRecording.log suggests that there is a Power calibration area error, but DVD recording works perfectly fine. I have not yet tested other CD-Rs.
Is there a possible reason and remedy for this issue?
Thx!
1.25 GHz Mac Mini G4 Mac OS X (10.4.10)

The batch of discs in question works just fine on other computers, while mine is able to burn other CD-Rs. I still don't know why the Prodiscs stopped working for me...

Superdrive no longer recognizes optical disks after upgrade to 10.5.5

It was handing down my 2007 MacBook Pro 2.2 gHz with a Superdrive fully functional running 10.5.4 with all the security updates. We booted of the Leopard install DVD and did a clean install. Then allowed Software Update to install 10.5.5 as well as anything else that needed updating. Now the MacBook Pro 15" will not mount any CD, DVD. It clicks for awhile then makes like a "boing" sound and kicks out the disk. So, the software install definitely caused this.
BTW, it also has the EFI firmware 1.5 installed and no new versions available for download. My new MacBook Pro has a newer Superdrive firmware.
Another odd thing is that booting from by Carbon Copy Cloner disk we made prior to the install also doesn't recognize any CD, DVD anymore!

Did the DVD drive work before you installed the updates but after you installed Leopard?
In the MBP forums, there were many issues with optical drive problems. There were a bunch of defective drives that failed after a time.
Does the drive show up in the System Profiler? And if so, what does it say?

Superdrive no longer recognizes CD, but works fine with DVD

my Superdrive seems to have a problem recognizing any type of CD media, but works fine with DVD media.
I reinstalled Leopard and still the same problem. I also zapped the NVRAM (this is an Intel 2.0 Ghz Mac Mini w/ 2 GB Ram.
Is there anything else I can do or do I just need to replace the drive?

Typically when this sort of symptom appears, it relates to a hardware failure, either due to a faulty lens, or dirt. You might try a lens cleaner to ensure it is not the latter.
Since this is a 2.0GHz mini, it ought to be still under warranty - if that is the case it would be wise to have Apple, or an approved service provider, check it and undertake any necessary repairs.

Drive no longer recognizes media

My iMac PowerPC G4 (1.25 GHz) for some reason no longer recognizes any media that is placed into it. At first I thought the issue was just discs that I burned myself -- they were recognized on other computers, but not mine -- so I tried to put in a commercial DVD but that doesn't work either.
When I look on System Profiler, if I click on "Disc Burning" System Profiler just crashes. Each and every time.
It is a SuperDrive that is installed in my computer.
Does anyone have any ideas for how to remedy this without a trip to the Genius Bar?
Thanks in advance! Happy New Year!

Well, the quick answer may be the original superdrive
in the computer could have failed, as they sometimes
do at various intervals of time and after some use.
A replacement drive may be found at places such as
MCE and other third party suppliers; or a newer one
(than the original part number) should be available
anywhere they have authorized Apple techs & where
they know their parts. The drive has a superior newer
replacement model, as some of the originals failed
after operating system upgrades and other incidental
activity; in addition to those failures due to materials,
wear and tear, or perhaps in a design which was later
superseded by an upgraded part number.
If you go into the situation where you may be having
an optical drive replaced, and it is confirmed, then
you have a choice; to have it done there or elsewhere.
If someone there can figure out a fast workaround or
lens cleaning, etc to get it working (they get dusty)
then you are OK for awhile longer until it really fails.
Short of actually having to boot the computer from the
internal optical drive, it may be better in the long run
to have a good external FireWire superdrive equivalent
and one that does not have region codes. That puts off
the likelihood of the original superdrive's eventual failure.
Mine still has the original, but it seldom sees use other
than to boot the computer from the factory DVD installer
for some aspects of computer and disk maintenance.
To have an use external drives (optical and hard disk)
can be a better way to go; unless you have a tower.
But, I suspect the internal optical drive may have failed
in the case of your computer's symptoms. Plan for the
worst and hope for the best. There are ways to test a
computer to see if the internal optical drive has failed;
some require an external optical drive and other means
to perform hardware tests & related troubleshooting tests.
If a tech goes into your iMac, be sure to get it cleaned well,
and the 3.6v. battery on the logic board replaced. More
RAM in the hidden slot can also be added; be sure it is of
high quality, since getting into there is not easy. A tech
can also be sure the machine is put together correctly;
since there is the thermal paste & duties to perform in it.
{About all the upgrading one can do to an iMac G4 can
be done when that upper dome is disassembled.}
The Apple Hardware Test is on the original boot install
DVD included with the iMac G4. Have you been able
to get that to work? Hold Option key to get into an odd
set of iconic menu choices; unlike running Installer,
where you'd hold the C key on startup... if it works,
there could be error messages in strange language.
PS: Sometimes, things happen in a computer which
has too much on the internal hard disk drive; in so
much as too much means the system can become
corrupted and some symptoms may appear to be
hardware failures. At some point, if that happens,
actual hard disk drive & operating system failures
may occur and be a troublesome matter. If the
software that reads optical media has become
corrupted due to hard drive contents being over-
written (too full, low free-space capacity, etc) then
other things would also be on their way out.
Good luck & happy computing!

I recently upgraded iTunes to 11.1.4.62 and then itunes would no longer recognize my iphone 4s and iPod

I recently upgraded iTunes to 11.1.4.62 and then itunes would no longer recognize my iphone 4s and iPod although I can see the iphone but NOT the iPod on the computer (windows 8.1 Pro). I checked everything , cable, services, stop and start and automatice, etc.and went through all the steps on the apple support site, to include removing all apple software in the designated order and reinstalling it. iTunes still doesn't see the iphone.
The Apple iPhone shows up only under protable Devices in the Device Manager window and has a Yellow ! warning triangle, and there is no Apple USB controller in the devices menu.under Universal Serial Bus Controllers. When I look under the properties of the Apple iphone, it says in Device Status, to reinstall the drivers for this device (Code 18).
When I do this, I get the following: "Windows found driver softweare for you device but encountered an error when attempting to install it" Apple Mobile Device Driver One of the installers for th this device cannot perform the installation at this time. I tried both suggested locations on the C: drive.
Also I can't seem to find out how to install the Apple USB Contoller or is that related to the problem above?
The iphone and my ipod work fine with this version of itunes on Windows 7 on my laptop. is it possible that I am missing a critical update from Microsoft on the driver and USB controller? I have been leery of installing them since my computer had problems with some updates in January.
I 've tried every thing listed in this forum, I think, and the Apple support page on this subject. Please help!

Version 11.1.5.5 of iTunes was just released today. If you update to that, does that help with the recognition troubles?

I'd love some help trying to figure out why my 2008 MacBook no longer recognizes my external drive and now is not downloading photos from my iphone....?

After many years of having no problems at all on my Macbook, I recently figured I should finally upgrade my OS. I did that about three weeks ago, updating to Snow Leopard (10.6.8). I used Time Machine at least once after the OS upgrade but now Time Machine no longer recognizes the external drive I have used for all these years to back up. The MacBook does not "see" it. (Disk Utility does however.) The computer then also stopped recognizing another La Cie back-up that I have and now... my iPhone cannot download photos? Yikes.
I have, of course, shut down numerous times, used different cables (that worked for some) and the two USB drives. I even used a firewire. Nothing worked. I also tried to "Repair disk" on Disk Utility. It didn't work either, giving me an error (that I didn't save, sorry).
I read many other discussions on the file format of the external drive and of course I'd be happy to reformat the external drives--however, it is obviously a tad nerve-wracking to reformat drives before having an accessible back-up. Suggestions? I do not remember what file format they have but am pretty sure it's not the Mac file system someone mentioned. The drives are a 2009 WD "My Passport Elite" and La Cie 2007 d2 Quadra,
In terms of other hardware available, we do have another MacBook Air but it has started rejecting both drives as well (without the Snow Leopard upgrade). We have an old Dell but it wouldn't have the disk space to help out much.
Any thoughts on the process involved would be welcome. Any ideas on the iPhone rejection would be helpful as well! It is a 30gig iPhone 4 that has 20 or so gigs free (not clear as iTunes says that there are abour 18 Gigs on the phone but 24 free gigs? I may be bad at math but that's 40 gigs...).
I am checking out iCloud but apparently there are only 55 gigs available?
Will be glad to hear any thoughts. Thanks!

Good afternoon Lyssa,
Phew. First of all, thanks in advance...these blogs are always comforting help!
So, to answer your questions: For the age of the hard drive.Well, I added memory a couple of years ago (RAM and hard drive). Being a mom leads me to eat up a fair amount of gigs with photos of my kids and, in fact, I think I entirely replaced the original drive, so it is a couple years younger than 2008 since I did that in March 2010. If there is some way to verify that (whether or not I replaced the entire drive), I'm all ears. I have 311 Gigs free, so it is not a space issue. I verified the startup disk on Disk Utilityand nothing showed up.
Question 1- What formats...
The La Cie is format Windows NT Filesystem 3G ....At the time that I bought it I was still using a PC as well as a Mac and was told by afriend to use this format...
The WD is Mac OS Extended (Journaled). I again tried to repair the WD last night and this is the error message: "Error: DiskUtility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Also, Time Machine tried again to back-up and gave me this error: "Files can't becopied onto the backup disk because it appears to be 'read only'. You may needto repair or reformat the disk using Disk Utility. If the disk can't berepaired, you must use a different disk for backups. Open Time Machinepreferences to select a different backup disk."
Question 2. Other cables...
I used two other cables with the WD and that didn't change anything.
Question 3... Fire Wire from the La Cie
Yes, I used the Firewire cable from the La Cie and it is indeed present, though still not visible in Finder. Since it is not Mac OSExtended I know that I can't use Time Machine with it.
So, in summary...
I can plug in the La Cie and it is functional on the MacBook, visible on Disk Utility but not visible in Finder. The WD drive is not visible and not functional. So we can think it is indeed the WD that is not working.... Also, the iphone photos did, in the end, get downloaded, so it is not something more general.
Causes...
I forgot to mention that there is a "lost+found" file on the WD which apparently points to a UNIX /OS issue?
Some kind of "insurance"?....
I'm curious about how people avoid this kind of issue. You just regularly replace back-up drives and hard drives before problems come up? Time Machine is great and saves many of us from disasters, however, knowing that your Time Machine back-ups are vulnerable makes the whole system insecure. No way to have alarms ring before the drive goes out?
As for ways ahead...
It seems that I ought to be able to copy off of the WD to the MacBook then erase it and reformat it and start over again. However, I haven’t been able to see its contents except on random occasions. If you have any ideas on how to copy the Time Machineback-ups from the WD, again, I'm all ears!

ITunes and iCloud no longer recognize Outlook on my computer

Since I got my iPhone several years ago, I have used Outlook via iTunes to sync my calendar, contacts, and other information.
I currently have an iPhone 4 with OS 5; I unfortunately have iTunes 10.5.2 running on a Windows 7 operating system.
I say "unfortunately" because despite my satisfaction with how these things all worked together, I am now totally fed up with Apple and it's supposed updates.
Today is Dec. 14, 2011. Two days ago, Apple released an "update" to supposedly address an audio issue. This morning, my computer and iPhone spoke to each other using iTunes -- I chose not to use iCloud when I downloaded the new OS 5.0 because I was not satisfied that it was consistently updating what I needed on my phone. It seems all it wants to do is update to iCloud.
This morning, an Apple alert about a new update showed up on my screen and I said okay to install because in the past there have been been few issues. NONE have caused my iTunes to insist there is no supported calendar program or to not show Outlook as an option for contacts.
This morning pre-update: everything worked as it was supposed to; after the update: NOTHING is working the way it is supposed to.
This ***** and is stupid, APPLE. It is very easy to get another kind of smartphone and these are all catching up with iPhone.
Issuing updates that make the system not work and WASTE HOURS OF MY TIME is no way to keep me as a customer or a way to encourage me to buy more apple products.
IN SUMMARY:
iPhone 4 with OS 5.0
iTunes 10.5.2 with Dec. 14 update
NO LONGER RECOGNIZES OUTLOOK ON MY SYSTEM.
I have wasted hours trying to fix this.

Hi, Linda from Folsom. Thanks for the message.
While I do run iolo system mechanic, my issues did not start until *after* I downloaded iTunes 10.5.2.
On the same date I updated iTunes, I also downloaded a Java update. I did these one after the other so didn't now which updated started the issue.
I later found that my issues were also related to iCloud usage for syncing, which I resolved this week by eliminating iCloud from my life (other than backing up my iPhone).
I posted something in the community about how I undid everything iCloud did to my Outlook, but my solution is only for those who no longer want to use iCloud with Outlook.
That's an interesting point about the iolo system because I didn't have any issues at all with it (until I updated iTunes).
I had a very similar system setup at the time as you do:
iPhone 4 with OS 5.0.1
Outlook 2007 (now I have 2010 version)
iTunes 10.5.2
Windows 7 home premium (now I have the Windows 7 ultimate version).
I will be interested to hear if your iolo system caused some issues as I do like using it for clean up on my hard drive. When I couldn't use Outlook, I went to "JustAsk.com" and paid the small fee to find out that you can repair office from the control panel programs list; this is what solved my issue.
If you haven't tried it, it's pretty easy:
Open Control Panel
Select Programs
Find Office on the programs list
RIGHT click on it
Select repair
Windows installer runs, then restart
After I did that, iPhone could see Outlook again. That could be where the registry issue is happening with iolo.
Hope this is helpful,
Cecilia

Installed latest itunes update and computer tried to burn a playlist to CD and realized computer no longer recognizes my CD/DVD drive. This is an APPLE Itunes issue. Help!. HPPavillion DV6 64 bit, windows 7

TS1363 Updated to iTunes to latest version 11.1.4.62 on my Windows 8 machine. iTunes no longer recognizes my 5th Gen Ipod. It does however recognize my 80gb Ipod Video. I've uninstalled and reinstalled iTunes as directed (twice) & rebooted pc. no luck.

I just updated iTunes to the 11.1.4.62 (as the pop up directed me to) on my Windows 8 machine. As a result iTunes will no longer recognize my 5th generation Ipod Nano (yes two). I receive a pop up saying "Ipod has been detected but could not be identified properly" I've followed the recommendations seveal times: a) disconnected and reconnected. b) rebooted computer c) unistalled and reinstalled iTunes d) tried different cables e) tried different USB porst f) rebooted Ipod.... the window keeps popping up like a middle finger (you get the point)
iTUnes WILL however, recognize my 4th gen Nano and my 80gb Video (classic) without problem
Needless to say, I'm frustrated and ticked off over all of this wasted time.
Anyone solved this issue yet?
Any good suggestions?
Please advise
Kindest regards,

c) unistalled and reinstalled iTunes

Windows 7 no longer recognizes my Pre

Not sure when it happened, maybe after I updated to OS 1.4.1.1, but my Windows 7 PC no longer recognizes my Pre. It used to, but now it doesn't. I have tried a cold restart for both the Pre and the laptop but still no success. Has this happened to anyone else? Any ideas from anyone?

Hello Luke and welcome to the forums;
There are several possible solutions to this issue, and we have a fairly comprehensive KB article that describes the available fixes. I recommend going through each step in order, testing for a connection after each step.

ITunes no longer recognizes my iPhone 4

I have had 3 iOS devices connecting to iTunes on Windows for more than 4 months. For some reason iTunes no longer recognizes my iPhone 4. My iPad and iPhone 4S still work as they should. Windows sees the iPhone 4, but it never shows up in iTunes. I followed the advice for getting services restarted in Windows, but since it's only one device that's an issue I'm thinking there may be an issue in the iPhone 4. Ideas?

try this, it worked for me...

MacBook Pro will no longer recognize new SSD via USB

I just received a brand-new 512 GB Samsung 840 Pro SSD from Newegg this morning.
I own a 15-inch MacBook Pro (Mid-2012) with 16 GB of RAM and a 2.3 GHz Core i7 running Mavericks (10.9.1).
Earlier today, I plugged in the SSD via a third-party USB-to-SATA adapter that I also purchased from Newegg at about the same time. The machine recognized the new drive, and I opened up Disk Utility to format the drive as Mac OS Extended (Journaled).
Once that finished, I used Carbon Copy Cloner to clone my existing HDD to the SSD. Before it began, the program asked me to create the Recovery HD, so I enabled that option. The rest of the process proceeded smoothly. I quit CCC, ejected the drive, and put it away for the rest of the workday.
When I arrived home tonight, I plugged the SSD back into the Mac in hopes of test-booting it externally. Unfortunately, the machine will no longer recognize that anything is plugged into the Mac. I find it highly unlikely that the USB adapter could be malfunctioning; I unboxed it this morning and it's been mere hours since the successful clone attempt. I also find it hard to believe that the SSD could be broken, either.
I tried to disable rEFIt and manually invoke the boot selection screen, but even when that happens, the drive fails to mount. For the same reason, I can't erase the drive to start over, either. I've tried both USB ports, as well as rebooting with the SSD connected and unconnected.
My research tells me that people often have problems trying to get SSDs to boot when they've been installed in the drive bay, but nothing I've seen suggests anyone's had a problem booting from the external SSD after a successful clone attempt. What am I missing?

I'd start by resetting the SMC. Follow the method for "a battery you should not remove yourself."
http://support.apple.com/kb/ht3964
I have no experience with Samsung SSD's, but I've read a number of posts here of people having problems with some of them. That could be a possibility.
The other thing you could try at this point is to swap the drives. If it's cloned already and the drive is good, it should boot. That would indicate the enclosure failed after the copy.

Macbook pro no longer recognizes external hard drive

Hi everyone,
My Macbook Pro (2013) running OS X 10.8.5 will no longer recognize my external hard drive.
The hard drive, a Maxtor OneTouch 4, is granted quite old (c. 5 years) but has been working fine with my Macbook pro since I bought it 2 years ago. It is too full to do time machine backups but I just need to get some files off of it. It doesn't appear in Finder or in Disk Utility when connected and turned on.
Since it's only stopped working recently I suspect some software update may have rendered it obsolete. I have also noticed some glitchiness with my USB ports, but some things work fine.
If anyone has any suggestions of what to try, I would really appreciate it! I really need to access those files.
Thanks very much in advance!

After upgrading to mountain lion aperture 3.3 no longer recognizes DNG files. Is this going to get fixed?

After upgrading to aperture 3.3 on mountain lion aperture no longer recognizes DNG files.
I have many DNG files already in my library. Aperture shows the thumbnail and will briefly flash what I think is the preview of the file but quickly changes to a gray triangle saying "unsupported image format". After which the thumbnail is replaced with an all black thumbnail.
Needless to say this is extremely disconcerting. I am concerned that aperture is not only refusing to display the existing DNG files but is also simultaneously corrupting the library and destroying my existing images.
fwiw, these DNG files were generated with a leica.
I have not attempted to import DNG images into my aperture library but I assume that would not go well.

Susan,
if it is the native raw format, that no longer is recognized, then try, if registering the CoreTypes.bundle with the OS again will help. This will tell MacOS which raw format types (and other media types) are supported.
Open a Terminal window and paste following line into the window, hit return. This is one very long line:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSe rvices.framework/Versions/A/Support/lsregister -R /System/Library/CoreServices/CoreTypes.bundle/Contents/Library

P.S: Some browsers cause a blank to be inserted between /Frameworks/LaunchSe rvices.framework/Versions
But it is "LaunchServices.framework", without blank. All in one line - the only blanks are needed between "lsregister" and "-R" and after "-R" .
