When I insert my Dvd-R it says The disk you inserted was not readable by this computer.Why is this happening ???

When I insert my Dvd-R cd it saids "The disk you inserted was not readable by this computer." Please help
thanks

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?

    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.

    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

    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 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! 

  • 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

  • IMac "The disk you inserted was not readable by your computer"

    My 2 year old iMac will no longer read dual layered DVD's. For example I just bought x-plane 10 and everytime I insert the disk a error message come up saying the disk you inserted was not readable by your computer, when the version I got is dual layered as for Mac OS X. Has anyone had the same problem with loading dual layered disks. Movie DVD's do not work and x-plane 10 does not work, but the office 2010 dvd and the MAC OS X dvd works, I don't think these two are dual layered.
    Please help Thanks
    X-plane 10 is for both mac and pc

    PLEASE HELP ME!!

  • HP Laserjet P1102w by USB "The disk you inserted is not readable by this computer"

    My HP Laserjet P1102w used to work fine with OS X10.10. Then it started saying "The disk you inserted is not readable by this computer" whenever I switched it on, but the printer still worked. This morning it didn't. I uninstalled the printer, but can't re-install it - it isn't listed when I click "+". I have tried a different USB cable, and a different USB port - same message. The HP website does not provide a downloadable driver, as far as I can see. What do I do? (The wireless connection to the printer stopped working ages ago. The printer still works with our two PCs via USB.)

    Hi Shapley,
    Repairing the disk permissions can be done as following:
    1. Open the the Applications folder.
    2. Go to the Utilities folder.
    3. Double-click on Disk Utility.
    4. Select the hard drive containing the boot volume.
    5. Go to the First Aid tab and select Repair Disk Permissions.
    Note: This process may take several minutes depending on the Mac and amount of permissions that need to be repaired. The Progress Log will indicate when the process has been completed.
    Next reboot your Mac and try plugging the USB again.
    If the same persist, a such may also happen due to a conflict with the HP Smart Install feature which is Windows Based only and being wrongly read by the Mac, in order to resolve a such a Windows based PC will be required. any laptop should meet the purpose, the printer will be installed automatically by connecting the USB.
    Next update and install the latest firmware below:
    http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=bi-115794- 2&cc=us&dlc=en&lc=en&os=4158&product=4110396&sw_lang=
    Next follow the HP Smart Install Control Utility below: Select the Printer and follow the on-screen steps to disable the feature for the printer.
    http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=lj-129224- 1&cc=us&dlc=en&lc=en&os=4158&product=4110396&sw_lang=
    NOw plug the USB back to your Mac and check for any difference
    Please let me know of any change,

  • 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 get this message whenever I turn on my printer: The disk you inserted is not readable by this computer. How can I fix this?

    Whenever I turn on my printer (HP OfficeJet Pro L7590), I get an error message that says: "The disk you inserted is not readable by this computer." Then I have to click "ignore" or "eject." I click ignore, and everything works as it should. But the error message is annoying, and it only started happening a few weeks ago. I got the same message when I was using OSX 10.4, and now that I've upgraded to 10.6.8, I'm still getting it. How do I get rid of it?
    Thanks!

    If you installed the Seagate software, remove it according to the manufacturer's instructions.

  • 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.

  • "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" Error

    Hi, I inserted my External Hardrive into my usb port today and got an error saying "The Disk You Inserted Was Not Readable."  I was wondering if someone could walk me through what to do.  I went to do "First Aid" but I am not able to click either the "Verify" or "Repair Disk" buttons. 
    What can I do?
    Thanks

    It has to be formatted as Mac OS Extended (Journaled).
    Do you have room on the startup drive for the stuff that is on there now - always assuming you get to it?
    If so, copy the contents (if you are able) to your internal hard drive, format the external, and copy back.
    Of course, if you do not yet have any files on your external HD the problem is over! Just format it!

  • The disk you inserted was not readable by this computer - Finalized video DVD

    Suddenly I have not been able to watch video DVD’s on my MacPro OS x 10.5.8 that I have recorded with my Panasonic DVR.  I am also not able to read some data DVDs.  I am able to read other data DVD’s and all the data CD’s I’ve tried.  My PowerBook G4 is able read and play all these disks including the video DVD’s recorded on my DVR.
    I use my DVR to record TV programs off the air and to transfer home movies from my camcorder to DVD.  I finalize the disk and then watch it later on my MacPro.  I also use the DVD as a way to get home movies into iMovie for editing.
    I’ve had no problems in the 3 years I’ve been doing this.  Now when I insert a video DVD recorded with my DVR I get the following message:
    “The disk you inserted was not readable by this computer”
    Before this happened I watched a commercially produced DVD movie on my MacPro for the first time.  I suspect this DVD changed something in my MacPro’s DVD player.
    Is there a way to get my MacPro back to the state where it will read a DVD video I have recorded on my DVR?  Is there a way to use Time Machine to revert back in time before the problem started?  I am using an external drive with Time Machine for backup.
    Thanks.  Bob

    I have a panasonic dvr pretty similar to yours, I hope (DMR EH55) and to transfer stuff to dvd, you have to change the drive over to dvd, put in the blank dvd, format it, then tick off the stuff you want copied, then choose high speed copy, then you have to wait, until the stuff gets copied, and the whole process finishes- dvd in the drive says formalized, this thing is necessary so that this dvd will play in dvd players, then you have to wait until it says it's done. if the dvd is not formalized, just copied and removed , then it will probably not play in dvd players. I've done what was mentioned before, and no problems, also check the brand of media you are using, and use a brush type dvd drive cleaner on your MacPro's DVD drive
    hopefully that helps
