Message on startup: The disk you inserted was not readable

Every time I start my computer I get a message:  The disk you inserted was not readable by this computer.  I've tried a number of things to stop it, no success.  Anyone know how to fix this?

try safe mode, try booting from DVD or another boot drive and repairing the drive or checking for hardware errors like  bad sectors.

  • 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?

    PRAM RESET
    Zap the PRAM
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Why does my memory stick all of a sudden trigger the message "The disk you inserted was not readable by this computer"?

    I bought a LaCie memory stick a couple of months ago. It worked fine. Now all of a sudden I get the message "The disk you inserted was not readable by this computer". What has happened? Is all my data lost? Can I retrieve it? I tried to fix it with Disk Utility (which at least correctly recognises the stick), and even though I can click on my memory stick I can't do anything to it. Any help would be greatly appreciated!!!

    According to an ASC member who claims to work for HP, this issue can be resolved by repairing the permissions of the startup volume in Disk Utility. I can't confirm, but it has apparently worked in at least one case.

  • 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

  • I've been getting the error message "The disk you inserted was not readable by the computer". I can't open system preferences, disk utility, or Time Machine. I'm guessing it has something to do with my external hard drive, although it hasn't been touched.

  • "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.

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

    Time machine was working just fine with my Maxtor external hard drive, once I had reformatted it, but this morning when I was booting up I got the message, "The disk you inserted was not readable by this computer." The message gave me the options of "initialize", "ignore", or "eject".
    What gives? Why the sudden change? If I initialize, then I lose all the previous saves and defeat the purpose of Time Machine in the first place.
    Any suggestions?

    Do you still have a drive with Mac OS X 10.4 installed on it? If you do, you can see if the drive mounts in 10.4. If you get the same message, it might be a problem with the drive and not be related to TM. I had a problem with an external Maxtor drive that TM corrupted, but the drive mounted without any problems. I just couldn't write to it in 10.5.
    If you can mount it in Mac OS 10.4 or on another Mac, see if you can repair the drive with Disk Utility or with a program like Disk Warrior. Another option you can try is to disconnect the drive and then reconnect it. If that doesn't work, try disconnecting it and rebooting and then connecting it again.
    If you can get the drive to mount, copy the TM files to another drive and then reformat the drive. See this page from Seagate/Maxtor for information on formatting the drive:

  • FRUSTRATED! Cannot access Seagate external HDD - message is "the disk you inserted was not readable by this computer"

    I get the message "the disk you inserted was not readable by this computer" when trying to access my Seagate external HDD.
    Disk Utility lists both the Seagate drive and volume but all options (verify disk, repair disk) are greyed out.
    It says the volume is unmounted and Windows_FAT_32.
    (The external HDD used to be formatted for NTFS, but when I moved across to Apple last year, I reformatted to FAT32).
    I haven't accessed the drive for a few months but the last time I did, it worked fine.
    I'm running OS X 10.9.5 on MBA bought last year.
    I've spent 2 hours trawling through blogs/mac forums/apple support and nearly bought Disk Warrior out of frustration, but surely there must be a simpler solution?
    I don't think I'm dealing with a corrupt drive, just an inaccessible one!
    Any help greatly appreciated, even if it is to pay the $$$ for DW...!
    Thanks, Jay

  • 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?

  • Unable to read usb memory stick + "the disk you inserted was not readable by this computer"

    Hi Everyone,
      Today I was tryign to use a brand new memory stick 8GB-Samsung PNY on my Mac Book Pro. (Mac OSX 10.7.5)
      1. I do not see this drive in the Finder.
       2. Diskutil could detect the drive.
       3. I was trying to put ubuntu image file on the drive from the terminal uitility and I have this error message in a dialog box:
          "the disk you inserted was not readable by this computer"
    4. Clicking on initialize helps me realise that the drive is detected. But I do not have a clue on how to proceed from here. I am new to Mac and its file system formats.
    The same issue happened with my 500GB external Western Digital Hard Drive. I was reading on forums that WD got some issues with Apple is trying to resolve. I expected to not have this road-block with another brand but it happened with my memory stick. Now I was forming an impression that something should be done to external storage devices inorder for me to use them Mac OSX.
    Kindly enlighten me and help overcome this issue.
    Thank You

    Thank You OGELTHORPE.
    I erased the memory stick and formatted to "Mac OS Extended(Journaled)".
    I attempted once again to use the "sudo dd" command from termial trying to copy the Ubuntu image file to the memory stick.
    The operation termainates with the same message
          "the disk you inserted was not readable by this computer"
    The termainal message says some bytes got transffered in so many seconds. It looks like this operation is being terminated in the middle.
    Have any suggestions and work arounds?

  • 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.
