I am getting an error that says the disk you inserted was not readable by this computer

There was a recent software update to the computer but that is all. When I plug the drive in it reacts but then I get this error. I have been having horrible luck with my macbook and now I have several weeks of my semester projects on this drive that I can no longer access any help is greatly appreciated.

This is a blank disc?  A disc you burned?   Burned discs have a relatively high failure rate if you buy cheap DVDs.  I bought some Dynex ones once and about one in every four fails.
Have you tried other DVDs to check if it is a drive issue?

  • 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

  • Why does it say \'The disk you inserted was not readable by this computer\'

    I have been using an HP Photosmart Plus B210a printer for a year.  Recently I have many inconsistent printing problems, it's slow, in a queue, just doesn't move until I reboot - pull out plug, download again etc... anyway now it's defunct I'm steaming - shall I chuck it and buy another if so which - thinking of HP Envy 120???  Anyway when I try to use usb and not eprint a box pops up saying: The disk you inserted was not readable by this computer.  So here lies the problem, but I;ve changed cables and still it pops up.  What does this mean?  My Lion 10.7 mac OX is as new as the printer.  Please advise, before I go insane.

    Sounds like you are having a configuration issue with the software. Initially, my first response will be to completely remove the software from your computer and reinstall it using the software that HP makes available to download. Here is a link to that download :
    http://h10025.www1.hp.com/ewfrf/wc/product?cc=us&lc=en&dlc=en&product=4021935
    Have you also considered trying a different method of communication (e.g. wirelessly or using an Ethernet cord)? This might allow me to make better assumptions on where the issue lays if I know the circumstances which lead to it. 
    Let me know and have a great day!

  • "The disk you inserted was not readable by this computer" error message

    Hello. I've had my iMac for a little over three months and I've encountered a strange problem. I play Warcraft III, and whenever I insert the disk into the drive, I get an error message saying "The disk you inserted was not readable by this computer" and it gives me the options to ignore or eject. I've gotten the same message with Starcraft as well. I also tried putting in the iPod Nano install disk with the same result. CD-Rs and Audio cds work smoothly though. I called Apple technical support and they told me to call 1-800-MY-APPLE to schedule an appointment with my local branch to bring it in. I just wanted to make sure no one on these forums can help me. All help is greatly appreciated. Thank you very much.
    iMac (Early 2006)   Mac OS X (10.4.6)  

    Steve, the original poster made clear he was on a core duo iMAC which ONLY runs OS X (discounting non Apple OSes of course!)
    Therefore there is no extension manager. But I guess he would thank you for trying to help anyway.

  • The disk you inserted was not readable by this computer-I KNOW!

    Hello
    Does anybody know how can I make the Finder ignore a certain volume and not prompt me to initialize it every time I plug it in?
    I have an external disk encrypted with a third-party utility (TrueCrypt) which means that OS X cannot mount it. The Finder is not happy with that, and prompts me with an annoying popup every time I connect the disk. The popup says: "The disk you inserted was not readable by this computer" and asks if I want to format it.
    How can I tell it to ignore that particular disk? I know it's not readable, that's on purpose!
    Alternatively, can I partition it in such a way to avoid the warning? I've tried both encrypting the whole disk (no readable partition map) and encrypting a single partition (with a valid MBR partition map.) Both ways cause the nagging.

    No.
    Truecrypt is not implemented in the System so that it mounts the encryptet volume automatically. that would be kind of stuipd, since its designed to only mount the drive with a password.
    When you plug in the external HD with an encrypted volume, finder tells us "i cant read that ****, format it".
    thats when you launch truecypt, select that partition, and enter its password.
    truecrypt then mounts the volume with MacFuse and it shows up in the finder.
    there is currently no way to make truecrypt prompt for a password automatically.
    so, the question is and remains, can we disable the finders "initialize volume" dialog?
    truecrypt is a terrific applications. too bad os x is yet too ignorant to non-known filesystems.

  • I plug in my printer and I get a message that says, "the disk you inserted is not readable." It didn't do this before but after I installed a segate hardrive software. I have removed the segate hardrive software but the message still appears.

    I plug in my printer and I get a message that says, "the disk you inserted is not readable." It didn't do this before but after I installed a segate hardrive software. I have removed the segate hardrive software but the message still appears. What can I do to remove this error.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; sudo crontab -l; } 2> /dev/null | open -f -a TextEdit 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    { launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; crontab -l 2> /dev/null; } | open -f -a TextEdit 
    Step 4
    ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Why do i get the "the disk you inserted was not readable by this computer" error when I don't even have a disk inserted?

    Why do I keep getting "the disk you inserted was not readable by this computer" caution message when I don't have a disk inserted???

    Unfortunately, I saw this error for the first time this morning. It's on my wife's iMac running Lion, and it appeared when the machine locked up on a Software Update screen prompting her to run an update (I'm assuming this was the recent Security Update).
    After numerous failed attempts to force-quit or otherwise safely restart, she hit the power button, and when the machine came back up it failed to recognize the startup disk. I've since successfully restarted from several different (external) startup disks without incident, but each time I attempt to fix the internal drive via Disk Utility the disk shows only as "Media" and all the usual options to Repair or Verify the Disk are greyed out, leaving only the Erase Disk option.
    Are we totally hosed?

  • 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.

    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

  • Audio CDs get "The disk you inserted was not readable by this computer"

    Hi All,
    This a near-duplicate of a message originally posted to the Snow Leopard forums.
    A couple months ago I upgraded to 10.6.4 from Leopard and configured a Boot Camp partition running Windows 7. Yesterday I discovered that whenever I put any audio CD, retail or burned, into the Macbook's drive I now get this message - "The disk you inserted was not readable by this computer" - with the options to ignore or eject. Disk Utility displays no unusual information, but a check of the system log on Console turned up this:
    Sep 8 11:05:21 Hard-Drive diskarbitrationd17: unable to probe /dev/disk1 (status code 0x00000047).
    Has anyone encountered this problem before? I suspect it's related to Boot Camp but not to the initial installation - CD reading worked fine right after the install. Note that this only affects CDs - Burned and retail DVDS read without any trouble.
    Michael
    P.S. The CDs tested include one just out of the shrink wrap, so please, no "have you checked your CDs they may be scratched" replies.

    Thanks, but no thanks. This is a software/hardware (driver?) issue, not a hardware issue alone. I kept a bootable backup copy of my 10.5.8 installation on an external drive, and a quick restart into that yields a desktop where CDs still load perfectly. I'm looking for power users with specific experience with this particular error and insights into what is causing it in 10.6.4.

    Does your printer have a slot for an SD card?  Is there are card in the slot?  If so, the computer is trying to mount that card as an external device.  It might be corrupted so that it can't be read.

  • My Sandisk cruzer thumb drive 4.0GB (which is very old, roughly 10 years and I'm not sure about the model) reads "The disk you inserted was not readable by this computer" when inserted in my Macbook pro 2010. How do I get it to work?

    My Macbook Pro 2010 with the latest OS does not open a particular Sandisk Cruzer 4.0GB (which is an old model, about 10 years) thumbdrive with the message "The disk you inserted was not readable by this computer". Will I be able to read it on my macbook?

    Is it readable in a Windows computer?  If not then you can try Disk Utility to repair the drive-- although that may be dangerous too.
    I haven't had this problem so I out of safe ideas.  There are ustilies out there.   I used the seach term "repair flash drive Mac OS X" to locate some of these.
    If the data is essential there are pay-for services to recover data looked the price was in the range $50 - $1000
    All the best.

  • Ext. HD error - "The disk you inserted was not readable by this computer"

    Hello world.
    I'm really stressed here.
    Whenever I insert my FireWire WD external HD, the "The disk you inserted was not readable by this computer" pops up, followed by three options; Ignore, Eject, Initiate.
    - DiskUtility doesn't work (Repair buttons are grayed out).
    - I managed to get some partition info through TestDisk. There is no option of repairing the partition table though.
    - Should I try DiskWarrior? How do I use it?

    This situation happened to me tonight, but instead of firewire, I was using esata. I bought disk warrior and it actually worked perfectly.
    Even though Disk Warrior was $100, it was definitely worth it.
