Imac 10, 1 won't read certain CDs

my imac , iMac10,1; Intel Core 2 Duo won't read certain bought CDS and spits them out. We can hear a whirring noise-- but not the clicking sound of the tracks being read-- and then, the CD comes out.
all software updates have been performed.
please help and thank you.

iMac Superdrives are notoriously finicky - what brand are the ones that didn't work? It could also be that the media is slightly scratched, dirty, or the printed side is not in perfect condition. My iMac (only) likes Verbatim.

My 24" iMac won't read audio cds--ejects them after about 15 seconds

My 24" intel iMac won't read audio cds. It ejects them after about 15 seconds. I have virtually never played cds on this machine in five years. It plays dads with no problem. Anybody have any feedback. I also saw a fix by deleting some presence files.

I saw this on a forum from about four years ago:
Trash the following folders:
com.apple.kernelcaches (from System/Library/Caches
extensions.kextcache (from System/Library
CDInfo.cidb (from Home/Library/Preferences
Restart
Could this be a fix.
Unfortunately, I can't reset PRAM. I've done it a thousand times over twenty years,but my machine simply boots up without the extra chimes.

Tecra 9100 won't read burned CDs

Hi.
I have a Tecra T9100 and the MAT****A DVDROM now won't*read burned CDs.
It has no problems when reading manufactured CDs / DVDs.
I noticed this after upgrading the BIOS with the 1.6 version.
Is there something else I need to do / configure / install ?
Thank you.

Hi
Maybe you should check different CDs from different manufacturers and should change the burning speed to the slowest one.
If this will not help then a CD/DVD drive issue might be the reason why not all disks are readable.
Cheers

New iMac (2015-Yosemite) won't read old Time Capsule files

My new iMac 2015 (OS X Yosemite 10.10.1) won't read (access) my old backup files on the Time Capsule. The old machine ( iMac 2007) is still backing up to the Time Capsule and still reads all the 2 years of backup files. New machine only allows access to the current backup since I turned on the new machine early-January. The old machine ( in another room ) accesses the Time Capsule via my local house wi-fi . There is no crossover between the backups. Old machine reads all up to now ON the old machine; new machine reads only that which is backed up on the new one since start-up. How do I get the new iMac to read the old files ?

Won't read selected CDs & CD-Rs

hey guys!
why is it that my iBook won't read/load selected CDs and CD-Rs which my PC can? how can i fix this problem? thanks.

I believe there are detailed instructions in the Nero user guide. Download it here http://www.nero.com/en/UserGuide_Burning_ROM6.html
and search it for "Mac".
Of course, if this doesn't help, please post back! But I hope it helps.

Imac 333 cd won't read

I just bought this computer for my daughter, but it won't read any discs. It just keeps asking me if I want to initialize them and then says they are locked. I know these programs work on anohter 333. I have never had a mac before and am lost.

Hi, Isabella -
It will do no good to try to initialize the disks, per the offer in the message from the OS. To initialize a disk means to erase and reformat it. Since a CD of the type you describe can not be erased, nothing will happen when you try to initialize them - nor should it.
Make sure the File Exchange control panel is active (checkmarked) in Extensions Manager.
Make sure the following items are physically present in the Extensions folder in System Folder (not all of them will show up in Extensions Manager, hence the need to make a physical check) -
Apple Audio Extension
Apple CD/DVD Driver
Apple Photo Access
Audio CD Access
Foreign File Access
ISO 9660 File Access
UDF Volume Access
If you have Toast installed on that machine, try disabling Toast's CD Reader extension.
Have you tried one of the original CDs that came with the machine, or a retail OS 9 Install CD, to confirm the drive is working at all?
If no CD at all is being read, you might try using an audio CD cleaning disk in the drive - if the lenses in the drive get too dusty or dirty, a disk can not be read.

Optical drive won't read certain discs?

Hello, this is my first post in the community and I am a novice with computers. I bought my iMac in 2010 at Apple and it has been the best computer I have ever owned. But for some reason starting today the optical drive won't read any type of cd's like a user's manual or software install disc. It tries but just ejects it back out. Now the strange part is I can put any dvd disc to play a movie and plays it perfectly with no problem at all. Has anyone had this happen to them or any thought on what is wrong. My wife has a macbook and hers works fine and I checked her system preferences for cd's/dvd and they are the same. I a running 10.6.8 OS. Thanks

The iMac supports the following CD types if it is one of these types and still won't read then it sounds like a CD hardware or software driver problem. If you re-load the software driver and it still doesn't work then I would then suggest you take it to an Apple store for repair.

CD/DVD drive won't read any CDs or DVDs

Whenever I insert a DVD, CD, or CD-ROM my computer won't read the disc. The computer starts making noise like it is reading the disc but then it stops. It tries 3 times (starts and stops) and then just spits the disc out. I can't watch movies, install software, etc. How do I fix this.

Before taking it or sending it anywhere I'd first try resetting PRAM…

10.5.7 Won't Read Audio CDs?

I installed 10.5.7 a couple of days ago. All went well and continues to do so except for 1 minor quirk, none of my audio CDs can be read by the dvd drive, I have managed to burn both CD and DVDs though using toast 8, but I'm unable to read audio CDs new AND old. Anyone one else having trouble with Audio CDs? [DVDs are fine]
Macbook 10.5.7, 4 gig ram 160gig hd

First, my MBP plays CDs fine, so it's not 10.5.7, at least in my case.
What happens when you insert an audio CD? Does it appear at all on the desktop?
Try a PRAM reset.
AFAIK, the lasers for reading CDs and DVDs are different. CDs use a 700nm laser, DVDs a 640nm.
The lasers for burning are different again.
It's just possible that the CD laser in your drive is not working.
Other than a PRAM reset, I am not sure what you can do.

Superdrive won't read certain discs in 10.5.8. WIN /MAC problem?

Have an early 2008 Mac Pro. Superdrive worked fine on 10.5.7 but since upgrade to 10.5.8 it will only read certain discs. Have a WIN/MAC rom of game Spore and the drive takes it in, sits for 2 minutes and spits it out. Could it be that the disc is WIN / MAC combo? Tried it on new apple MacBook Pro running 10.5.7 and drive read it fine. Does Mac need to issue a firmware update for Mac Pros? Know it recently upgraded Macminis and MacBook firmwares. Could it be software issue or corrupt preferences? Tried Ram zap and permissions repair and no go. Hope Apple is on this cause I heard others with similar issues.

I can tell you this - I have two Superdrives in my Mac Pro, both Pioneer, and experienced the problem you are reporting with previous OS X updates. I recently upgraded to Snow Leopard and after renting a bunch of DVDs, many of whom would generally not work in the past and I'd be forced to use a Lacie USB Slim Drive, all suddenly worked instantly, on the first try.
So it may be a software thing with 10.5.8. Carbon Copy your current system over to an external USB drive then upgrade to Snow Leopard and see if that doesn't make a difference. If it doesn't, and you don't want SL, copy back your previous 10.5.8 system. Can't hurt anything doing that. And if SL fixes the problem you can always update the external USB drive.

Vaio SVE15115FXS Won't read dvd/cds

Recently my Viao (model referenced in title) stopped reading dvds/cds. The tray ejects and the disc spins for a few seconds and then nothing. The drive is not listed in Explorer. I uninstalled the drive and restarted the PC but did not fix the problem. I've been searching for hours on how to repair this. Any advice you guys can provide is greatly appreciated. Thanks

IMac G5 won't read any CDs but DVDs work fine

I have an iMac G5 with a PIONEER DVD-RW DVR-K04L drive
and firmware revision D441.
Just recently it stopped accepting any CDs (commercial CDs, software CDs, blank CD-Rs). It buzzes and grinds and groans and then spits them back out, but refuses to mount them. The only exception is the Apple OX Installation CD that came with the machine - that one works without a hitch. DVDs play fine and I can burn to blank DVDs. The problem is only with CDs.
I've tried suggestions from the forums:
- reset PRAM and NVRAM
- trashed com.apple.kernecaches, Extensions.kextcache, and CD Info.cidb and then rebooted
- fixed permissions
- verified disks
Not sure what else to do - but I would appreciate any suggestions - since it reads the Apple installation CD, does this mean it's not a hardware problem but a software problem?

You will need to take it
to your local Apple Authorized Service Provider and
have them take a look at it. Hopefully your iMac is
still under warranty or AppleCare.
Thanks for the reply.
Is it possible to install a replacement unit on my own - or is this definitely not a do-it-yourself type fix? Also are there more reliable internal dual layer DVD/CD burners than the one the iMac G5 came with?
If I decide to simply plug in an external burner, are the external burners compatible with iLife 06 (iDVD and iTunes)?
Thanks.

After updates my iMac OS X 10.6.8 won't read certain .mov files

After updates on my iMac OS X 10.6.8 .mov files shot with the JVC HD200 will no longer play! Everything was fine before the updates. I keep getting the error message: invalid public movie atom. I was told it may have been from the iTunes update so I deleted iTunes and both versions of quicktime that I have and reinstalled earlier versions. Still no luck:( Any suggestions??

Based on the behavior my theory is that one or more of the Quicktime codecs has been damaged. FCP7 installs a variety of codecs that don't come with every Mac which gives you additional format support. You should not need to purchase that component as it is part of the FCP7 package. That suggests to me that 1 or more of the FCP7 installed codecs is damaged.
At this point I would suggest 3 things:
1. Install the combo update as a I suggested above if you haven't already (If those don't work then reinstall the last update: http://support.apple.com/kb/DL1400)
2. If you have a complete backup of your system (like with Time Machine), restore the contents of /Library/Quicktime/ from the backup from before the update was installed, restart the computer and see if it works.
3. Post your issue in the FCP7 forum and ask how to completely remove and reinstall FCP7 and all it's components (last I checked it requires a complete Erase and Install but I'm not a FCP person so ask the experts first): https://discussions.apple.com/community/professional_applications/final_cut_stud io
Side note: If the files open in VLC and you don't want to do all the above work right now (up to you obviously), you should be able to save the files out in a readable format by going to File > Exporting / Streaming Wizard. Personally I'd try to get your system back the way it was by taking the above steps but you have to balance your immediate need vs. time spent to fix this long term.
Best of luck to you!

Sept. 2006 17" 1.83GHz Intel iMac Combo drive won't read discs...

When I insert a CD (audio or data), the drive spits the disc out after about 15-20 sec. Nothing shows up. Nothing said. The disc just comes back out. Hardware Info shows the drive is there:
MATSHITACD-RW CW-8124:
Model:          MATSHITACD-RW CW-8124
Revision:          DACH
Serial Number:
Detachable Drive:          No
Protocol:          ATAPI
Unit Number:          0
Socket Type:          Internal
Low Power Polling:          Yes
Power Off:          No
But nothing else. Doesn't show the serial number either. Can't find any tools to test the drive with. A friend suggests I remove the drive and try manually cleaning the lens (Using CD/DVD cleaning disc did nothing). But I don't want to go to all that trouble, if there isn't a more than likely chance of it working. Too much disassembly/reassembly effort I'd rather just replace the drive while I'm in there.
I don't have the original discs that came with this system, so I can't run AHT. I'm told it won't tell me anything either, just that the drive is there, which the Hardware Info already says.
Should I try to go in and manually clean the lens or just replace the drive? Has anyone else manually cleaned their lens and had their drive work or is replacement really the only option at this point?
I'm told I should just get a USB external CD/DVD drive and be done with it... but I'd like to restore this computer to fully working order, if possible.

The Early iMac's are one of the most difficult iMac's to open and work on. Another problem given it's age, is that display cables and other connections are very brittle and it is very likely that more harm than good will come from working on it.
On that note: I suggest finding and using an OS X compatible External tray loading CD/DVD drive for several reasons.
1. External CD/DVD drives are faster and more reliable than slim-line super drives.
2. For about the same cost or less, a good External CD/DVD drive should also give you the ability to burn CDs and DVDs.
3. Using an External CD/DVD drive is a lot easier than ripping into the iMac and replacing the internal drive.
Personally I am happily using an older LG GE24LU20 with both my Early Core Duo and Mac Mini, but others here have also recommended that the GP10 DVD and Blu-ray, the LaCie's and the OWC FireWire drives are all very good solution for a busted internal super or combo drive.

Installed iTunes and now my pc won't read any cds-PLEASE HELP!

Anyone have an answer for this? It won't recognize anything...audio cds, cd-roms, nothing. If I go into my computer, the cd drive isn't even listed on there.

Sorry, was at work. Ok, here's the diagnostics:
Microsoft Windows XP Home Edition Service Pack 2 (Build 2600)
iTunes 4.7.1.30
CD Driver 2.0.4.0
CD Driver DLL 2.0.2.0
LowerFilters: PxHelp20 (2.0.0.0),
UpperFilters: GEARAspiWDM (2.0.4.0),
Video Driver: NVIDIA GeForce4 420 Go 32M GeForce4 420 Go 32M
Check the website of your computer manufacturer or video card vendor to verify that you have the latest video drivers.
IDE\CdRomTOSHIBADVD-ROM_SD-R2512________________1A04___
Failed while scanning for CD / DVD drives, error 2380.
Virtual drives can sometimes interfere with reading and writing CDs in iTunes. If this is a virtual drive and you are having problems with other drives, try uninstalling the virtual CD application.
