Music CD's Not Readable

When I insert a Music CD, I get a Disk Insertion message "The disk you inserted was not readable by this computer." I can read the CDs on 10.3.9 just fine, but not under 10.4.3. Data CDs and DVD read fine under 10.4.3. If I choose the Ignore option, Disk Utility fully recognizes the disk, but the Mount option is not selectable. Where do I start looking to get the system to recognize them again.

Hi William,
I don't know if this will work but its worth a shot:
Firstly, delete the finder's preference file located in YourUserName/Library/Preferences/com.apple.finder.plist
Next I would delete everything in the chache folder. (YourUserName/Library/Cache) You could however, if you wished just move the cache folder to another location (Like the desktop) if you wish to put it back after. Don't worry though - deleting the chache will not damage anything and in some cases will makes things better.
After deleting the chache and the preference file go to system preferences and select CD's & DVD's.
Have the options as follows: Open finder, Open finder, Open iTunes, Open iPhoto, Open DVD Player.
Now restart and when you're booted back up, insert a music CD.
It might be best if you try a few others after if the first one doesn't work, as the disk may be faulty.
Hope this helps

Music CD error : Not Readable

Hello,
I have a brand new iMac flatpanel. Today when I tried to put in a music CD, I get an error: The disk you inserted was not readable by this computer. This was actually working yesterday.
However, when I log out of the computer and log in as Admin..the CD player works properly.
Any suggestions.

Mokelly, Welcome to the discussion area!

the disk you inserted was not readable by this computer. (when putting ipod into mac) help,. now have no music on my ipod. how do i sort this out?

- Verify the file and disk formats on your camcorder and on your friend computer whether they support what you want to do. Also, if you are using a specific application to do the task, you may need to verify an application whether it supports the file format (e.g. MPEG4, Apple Intermediate Codec).
- Verify the device cable type whether Mac OS X 10.4.x supports.
- Verify the device compatibility with Mac OS X 10.4.x.
- Check an available firmware or driver for the camcorder that has developed after Mac OS X 10.4.4.
- Try diagnosing and repairing local hard disk and camcorder's drive directory.
- Verify disks permissions issue.
- Verify whether the disk is TOO warm or cold to read.
- If every troubleshooting does not solve the issue, consider to reformat the camcorder drive.

Disc Burner. Why are some files not readable or writeable?

Hello,
I am trying to backup my friends computer files on a beige G3 (233 MHz). I am burning about 6 DVDs of AIF music files. Most of the files are about 30 - 40 Megs in size. Often I receive error messages on particular files that read:
"The operation cannot be completed because some data cannot be read or written.
(Error code - 36)"
Followed by the choices: "Stop" or "Continue".
I have a bad feeling that my startup disk is too small but I am not sure.
Most of the files work fine. However some of the files cause disc burner to not be able to use them in the disc image before I burn. Why would this be?
Here are the specifications:
Computer: beige G3 with two hard drives (one SCSI and one ATA hard drive) and a Pioneer DVR-110D DVD writer which is Apple supported (Apple system profiler indicates Apple supported on this DVD writer). My blank DVD disks are Sony Vermatim DVD-R (1 - 16x speed support). Although I think my beige G3 only writes them at about 2 or 4x.
I am using OS 10.1.5. My startup disk which has OS 10.1.5 in it is a 4 GIG SCSI disk. Is this big enough for a startup disk (for creating 4.5 GIG DVDs)? My files are on the second hard drive which is a 40 GIG ATA disk.
I have a bad feeling that my OSX startup drive is too small for disk burning - it is only 4 GIGs in total and OSX Disc burner (Disc copy) is first making a disk image on my startup volume before it burns it. Perhaps that disk image is too large for the startup volume. Is there any way I could ask OSX to put this disk image on the second larger hard drive instead (not the startup drive?).
Here is my process (I hope I am doing this right - I am new at this):
1. I first insert a blank DVD-R
2. A message pops up asking my if I would like to create a blank disc image for this disk (I think this is the typical Disk Copy utility window. I say "yes" and give it a name and choose the "DVD-R or DVD-RAM" option. (I am not sure if there are other important settings to choose here or better settings to use but I guessed the other options that seemed obvious. A blank disk image is created with an icon that looks like a DVD disk.
3. Then I drag my chosen files to this blank disc image. It takes about 30 minutes to copy over. Thats when I receive the error message that some files couldn't be "read or written". The other files work fine but it would be nice if they all worked.
Why would some files not be readable or writeable?
4. Then I choose file/burn in the top menu and the DVD is created. This takes another 20 - 30 minutes. At the very end of the process another message pops up saying:
"Sorry the operation could not be completed because an unexpected error occured (error code -28)" Followed by an "OK" button.
However all the files that made it onto the final DVD are fine - its just that its not all of the ones I originally chose in the first step when dragging to create the disk image.
Am I doing this the right way?
Why are some files not "readable or writeable" as it indicates in the error message?
Is my 4 GIG startup disk too small for this? or are the music files possibly corrupt? or could there be some other possible problem?
Thanks

To follow up, I have some good news. After following your advice Kappy, it now works very well Thanks! Instead of using the 4 GIG volume for the OS, I am now using an 8 GIG partition on an 80 GIG drive. So now the OS has some room to operate. No disk errors occured on my first DVD
Now there was one problem. The second DVD burned gave me an error. I am not sure why but I am going to guess that because I had to installed the OS onto an 8 GIG partition maybe the OS needs to be rebooted in between disk burns because although 8 GIGs is certainly greater than the 4 GIGs I gave it last time, it still isn't a lot of space - maybe just enough to do one DVD at a time. Thats only a guess. So I rebooted to see if that clears the system out ready for the next DVD and I am trying to burn the second DVD again. If I remember I will report back. In any case, yes, this seems to be working. I hope this second DVD burns well too.
Thanks Kappy

How do I view and open all my files again that are on my external hard drive?? Error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject.

I have recently purchased Toshiba 1TB hard drive and I set it up and I was able to transfer all my files onto it such as my music, photos, documents. I had correctly ejected and used it again and all these files were safely stored and accessible afterwards. However after I rebooted my computer as it had been going slow and I had too much clogging it up once I reconnected the external hard drive I have error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject. How do I access all my files? I set it up to work on both mac and windows. I have tried both another mac and windows computer and same issue occurs?? I am worried that all my personal files are gone but am confused as the drive has had absolutely no damage to it as it was in a very short time frame and its never left the same spot. Any help would be greatly appreciated. Thanks

Thanks for your quick response. I had a look at your discussion... I tried it on a Windows machine and I thought that was compatible with ExFAT?
Therefore I need to attempt to use my external hard drive with a machine that boasts OS X 10.6.5 or above and then it should work?
Thanks

CD not readable but DVD works

My early 2010 MBP has started shwoing the following error when I insert a CD:
"The disk you inserted was not readable by this computer."
DVDs play with no problem at all and also, if I chose the ignore the ignore option to the CD error above, I can use the old Songbird app to rip music from CDs in to FLAC format - again with no problem. I ran a CD cleaner through the drive but no difference.
I have also tried starting the macbook with 'D' pressed to get the hardware diagnostics but this just gives me a white screen for a while before booting up normally.
Running Mavericks, Verified, disk and repaired permissions.
Thanks in advance.

I've already used a cleaning CD to no effect.
It still reads CDs using songbird, however I can no longer import them into itunes. I've tried redownloading itunes as well.
I have since dug out the CDROMs/DVDs that came with it(which play ok) and did a 'D' restart to do a diagnostics test and it didn't find any errors at all.

External Disk Not Readable by OSX after Setting Drive Letter in Windows 7

My external hard drive, which was previously formatted as Mac OS Extended (Journaled), contains all of my purchased music. I have this external drive connected directly to my iMac via USB. My iTunes in OS X points to this drive.
After installing Boot Camp, I was able to read this external hard drive in Windows 7, but I changed the drive letter used in Windows 7 from E: to G:. Bad idea, apparently...
Now when I boot into OS X, I can no longer read the drive (although I can read it in Windows 7 just fine). I get the error message:
"The disk you inserted was not readable by this computer." [Initialize] [Ignore] [Eject]
When I use Disk Utility to attempt to Repair Disk, I get the following error:
"2010-11-24 08:43:41 -0800: Verify and Repair volume “disk2s2”
2010-11-24 08:43:41 -0800: Starting repair tool:

2010-11-24 08:43:41 -0800: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
I've searched for this issue in these forums and on the web and have not yet found a solution.
Is there any way to repair this external drive so that I can again read/write to it in OS X (WITHOUT losing my music)?
Thanks!

I had this exact problem. I bought a 1 TB My Book, formatted it with Disk Utility, and completed a successful backup. I also had some home videos on it and was using about 40% of the drive. One day, about a week later, I had the same "disk unreadable" message and soon panicked. Tried everything, but finally spent $100 for Disk Warrior and I was able to get my videos off, but it wasn't able to fix my drive, DW said I didn't have enough memory.
I reformatted and put my videos back on, but now will use a different drive for backups, so if it fails again I only lose my backups.

Suddenly my 1 TB Western Digital external hard drive has decided to give me a "the disk you inserted was not readable by this computer" error

I was playing music on iTunes (my iTunes library is stored on the hard drive) when I realized that it was running slow and giving me some pinwheels. So, I force quit iTunes, ejected the hard drive, waited a couple of seconds and plugged it back in. To my surprise it gave me an error that said "The disk you insterted is not readable by this computer" with the options to initialize, ignore, and eject. I have been searching Google, YouTube, and other forums for fixes (I am not too handy with Terminal without some assistance). I am able to go to Disk Utility and I see the drive there, and when I go to the partition is says "not mounted" I have tried repairing the disk only to get the notificiation that tells me Disk Utility is unable to repair the disk. I also ran Terminal and tried doing diskutil repairDisk and repairVolume to no avail. Below you can see the information I have gotten from Disk Ultilty and Terminal. Any and all help would be greatly appreciated as I have my music library, art projects, and other very important data on this drive! Thank you in advance!

Yikes, doesn't look too good. But there are still things you can try.
I noticed the disk is formatted as MS-DOS FAT32. While such disks can be read and used on Macs, it's better to set up your disks formatted for the Mac. For one thing, the Mac disk repair tools don't work as well on FAT32 (PC-style) disks. Which might be why Disk Utility did not succeed.
I suggest using a PC running Windows to connect the drive to and see if the data are all visible, and if not, run the built in disk check tools in Windows. Also, WD disks usually come with disk tools on the drive, did yours come with those? Either for the PC and/or Mac? You might be able to download them from the WD sites.

Can somebody please please help me! External harddrive not readable due to dumb mistake!

What is quite possibly one of the dumbest decisions i ever made in my life, I disconnected my external harddrive from my imac & plugged it into a laptop that has Windows 7 to trasfer footage from there to my imac more quicker. I clciked an option that allowed me to assign a letter to it to it can be read by the laptop (however, I would of needed to format the harddrive which I thankfully didn't). Please understand that erasing the entire harddrive is NOT an option! I am a filmmaker & I have so many years of work on there, including videos, music, & documents.
When the computer starts up I get hit with "The disk you inserted was not readable by this computer"! I tried Disk Utiity & even though it recognizes the drive's existence, I cannot repair or mount...nor can I access any of the files! I also tried Diskwarrior & got "directory cannot be rebuilt, the file system is unsupported".
If theres anything you guys can do to help me, please do so. My life was on that harddrive & losing it would be the most devistating thing I could ever experience. A movie I finished not too long ago...is also on that harddrive. I'll send you a full video completely thanking you for your help!

Call a professional data recovery service such as DriveSavers. Their services are very expensive, but without backups, you have no choice but to pay whatever they ask.

first time posting so not sure this ended up in correct area...
I had same issue except only repairing the permissions didn't solve anything for me. *_If you recently upgraded your iTunes to 8.2_* check your permissions for errors, fix the errors, then restart computer and if that doesn't fix it, then try one of the 3 solutions below as there is a *known burn issue with the recent 8.2 update!*
My permission errors - permissions differ on ./Applications/iTunes.app/contents... etc, should be -rw-rw-r--, they are -rwxrwxr-x
I called Apple Care and we figured out 3 work arounds til a fix is released.
Solutions 1,2 are recommended by Apple Care. I used solutions 1 (easy) and then 3 (complicated).
Option 3 is a pain and takes A LOT of time and HD space or external HD if you have tons of music, podcasts, audiobooks, etc, loaded into your iTunes.
_*3 possible solutions:*_
1. Use the Finder window already built in the mac (to burn onto blank cds) -
Open Finder Window, go to File in the Menu Bar at top of computer, create a new Burn Folder, drag items to the folder and click on the burn icon inside the folder, insert blank disk when asked, add name, select burn speed, burn the cd.
2. Use the app Burn 2.3U -
Found at Apple.com in download section works like a Finder Window and converts audo files to MP3 automatically. (You can set up iTunes to do this as well)
3. Install an older version of iTunes 8.0.2 (couldn't find 8.1 thru 8.1.051) -
I found 8.0.2 at Apple.com, this process is complicated and you will need lots of HD space or external HD to do this because you'll want to back up your music library and you will need to delete version 8.2 BEFORE trying to install an older version. Otherwise stick with option 1 or 2 til a fix is released by Apple.
I ruined 8 blank cd's that actually burned but then I got the error message "the disk you inserted was not readable by this computer (Error)" at end of burn cycle and sometimes early disk ejections. _*I had no problems before the iTunes update in the past 5 days.*_ Still can't read/play the 8 disks but the problem went away!
I had burned 20 cds no problem last week with same media disks that were producing errors after doing the iTunes update, now after chosing to downgrade my iTunes I'm back to burning with no issues!
8.2 has 2 versions 32bit or 64bit, one of them may be PC/Windows version only but not sure which one I upgraded to or if that's even a factor with the permission errors I had.
Best wishes

DVDs not readable after upgrade

I recently upgraded to iLife '11 and since then I get the following message box when inserting a movie dvd: "The disk you inserted was not readable by this computer." with the option to ignore or eject. I know that it worked fine a few days before the upgrade and have tried several dvd's with the same result. iTunes reads music cd's just fine. Is there a setting that I need to correct that might have changed during the install? Just wondering if anyone else has had this problem. Appreciate any suggestions.

Also solved my problem too! I also recently bought a Lexar flash drive and in installed some software with it. Didn't notice any problems until today when I inserted a DVD and it wasn't 'recognised'.
After seeing this thread I removed LexarFilterScheme.kext from my Extensions folder and now DVD Player works properly again. Thanks!

Need help with Error message "The disk you inserted was not readable by this computer"

I got this message this afternoon "The disk you inserted was not readable by this computer" with the options to either "Ignore" or Eject"
This is in reference to my External Hard Drive "Buffalo" 1TB. I just got my Mac 27inch this week and when i got it i hooked up this hard drive to it, historically used on my old windows machine, but was still FAT32 formatted. I was able to upload all my pics to Aperture and music to iTunes. Was able to surf the data no problem.
This afternoon i noticed that it was no longer visible in the "Finder" and afre rebooting several times, got this message "The disk you inserted was not readable by this computer"
Neither the mac nor the HD was moved since yesterday, early this am when it worked.
Is there an easy fix to this? whats going on.
Some info:
I had used this external storage unit for more then a year.
I sold my PC today so cant test if the hard drive still works on that.
I have the latest 27 inch mac (2.7GHz)
Storage is connected to a power source ( I tried both USB and FireWire, both yield the same message)
Any advice?

Have you tried the Repair Disk feature in Disk Utility?

F this error message "The disk you inserted was not readable by this computer" with 2 radio buttons "Ignore" or "reject" It comes up every time I start my new printer. How do I get rid of it?

When installing my new HP printer I received the following error message when I inserted the software install disk: "The disk you inserted was not readable by this computer" with 2 radio buttons "Ignore" or "reject" I was able to eject the disk but the message remains. Now every time I start up the printer this error message pops up on my computer. I have since used the disk drive successfully for music CD's etc. How can I get rid of this message?

External Hard drive "not readable", does not show up in Disk Warrior either. Help me, please!

I have a 500gb G Drive Slim that is almost brand new. I accidentally pulled the cord out when it was connected, and now when I try to open it, it says "not readable by this computer." This is what I see when I go into disc utility:
I called G Drive, and they told me to download Disk Warrior 4. I did, and this is what I see when I open it:
My hard drive doesn't show up...i'm not sure if i'm doing something wrong but I just paid $100 dollars for this and I'd really like some help. I read the manual and it wasn't helpful at all.
Please help me!

Make sure it's format is Mac OS Extended (Journeled).
To check it's format, plug in the External HDD and search Disk Utility in the spotlight. Click the External HDD and go to the Partition tab. If it isn't Mac OS Extended change it and format it.
You shouldn't need any of these external applications to use it. I have one and use it like a flash drive.

External Seagate drive suddenly "not readable" by iMac

I'm having a problem with a Seagate Backup Plus external desktop hard drive.
It was working fine, but then I restarted my computer and got a window with the error message: "The disk you inserted was not readable by this computer." and options to Initialize…, Ignore, or Eject.
I rebooted my computer a few times, and each time I get the same error message. When I open Disk Utility, I see the hard drive listed in the side bar, but it is not mounted and will not mount. Each time it is labeled something like "disk2s2," "disk10s2" or "disk6s2," etc. That changes slightly each time like that, but seems to always begin with "disk" and end with "s2."
I ran repair disk and got the following result:
The drive is about three months old. I think it did something like this when I first bought it (I remember seeing the "disk2s2" label in the Disk Utility sidebar), but restarting solved it then. Now it seems to keep happening every time I restart.
I would really appreciate any help or information any of you can provide.

External hard drive spontaneously unmounted? Try these tips:
NEW FIRMWARE: Try updating your external hard drive's firmware, which is available from your drive manufacturers Web site--or just use VersionTracker's (www.versiontracker.com) search function to find it. Be sure to back up your data before applying the update, and carefully follow the manufacturers instructions.
OUT OF iSIGHT: If you're using an iSight camera while you're using a FireWire drive, the camera may be interfering with the drive's ability to stay mounted. Try temporarily disconnecting your iSight and moving it to a separate FireWire port. If you have multiple FireWire devices, try using a FireWire hub.
POWER PROBLEM: A faulty power adapter could be causing your drive to unmount. Your drive may not be getting enough juice to stay on, causing the drive to turn off and thereby unmounting it from your Mac. Alternately, the power adapter may not be providing a steady amount of power, causing your drive to turn on and off. Try replacing the adapter. If you can't get a replacement adapter from the hard drive manufacturer, try your local electronics store. Just make sure the adapter you choose has the same connector and input/output voltage. you can find the input/output voltage on the adapter itself.
Cheers!
