    I did this but while in the Disc Repair, I was unable to select anything. I tried using the keyboard but that didn't help.
    Any ideas of what I can do so I can repair by disc.
    Thanks

    Is that what you tried?   If not, or if you're not sure, see #6 in Using Disk Utility, especially the yellow box.

  • Unable to access data after running disc repair

    I ran disc repair today as there is a problem with the hard drive. On restart the computer is displaying a login page. I have never had to login and now I cannot access any of my files or applications. How can I access my data?

  • Disc repair not an option

    i have been having trouble with disc permissions not completing for a little while, and today i noticed the disc repair stays "grayed out" in the first aid menu. i booted the disc from the install disc (which runs 10.2.4) and the disc repair went through once, corrected a single issue and went through perfectly the second time.
    even so, it doesn't show up when i start it from the hard drive (which runs 10.2.8)
    is this a problem or does it simply indicate that it doesn't need to be run?

    You can't run Repair Disk or any other (reliable)
    disk utility using the program on the drive being
    repaired; you need to boot from a different volume
    (e.g., the OS X Install disk) to repair the hard
    drive. The basic principle is that you can't make
    changes to the drive from which the OS and utility
    program are running at the time. You can run Verify
    Disk using the hard drive's copy of Disk Utility
    while booted from the hard drive.
    When I attempt to run Disk First Aid from the booted OSX install disk, I get the same message. It states that an internal error has occurred and disk Repair has lost contact with the Disk Management Tool. Running DiskWarrior shows no problem.
    What can I do about that?

  • Disc repair function for macbookpro

    how can i access the disc repair function in macbookpro, and will it resolve the problem "start up disc is full delete files"? keep getting this message and there is no indication of how to resolve the problem.

    Your disk is about to fill up to the point where it will not boot.  Take action quickly to delete files you do not need so you will not reach that point.
    You should maintain a minimum of 10 GB of free space and it is best to keep about 15% free, whichever is bigger.  Your system can slow down if there is not enough free disk space.
    Initial easy steps to gain disk space:
    - Delete all files in the Downloads folder.
      Empty the Trash.
    - Start iPhoto.  Empty its trash.
    - Boot in Safe Mode.
    http://support.apple.com/kb/HT1564
    - Restart in normal mode.
    Deleting and offloading files:
    Backup:
    Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. 
    Deleting and Offloading files:
    Use OmniDiskSweeper  http://www.omnigroup.com/more to find large folders and files to delete or offload.  Do not touch any system files.  Do not offload files onto a Time Machine disk.   Do not offload your entire user folder. Do not rely on restoring files from Time Machine; delete only those files you never want to see again.   Do delete or offload seldom use folders/files in your user folder.  Remember to empty the trash after trashing the files.
    Configure Time Machine to backup your offload disk (if you have one);
     > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list. 
    Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

  • I tried upgrading to MountaIN lION HOWEVER i WASNT ABLE TO Install.  I then tried reinstallling Snow leopard but once again it will not let me install stating there are errors on the disc.  I have run disc repair on disc utility but it wont allow me

    I was told to reinstall Snow leopard which I did .  More troubles! It then came up cannot iinstall as there are errors.  Tried going into disc utilities and repair but once again it stated iin red I cannot proceed.  can anyone help me here.  Before this was happening my system was slowing right down with the beach ball making an apearance after tapping the mouse or typing text.

    So you are trying to reinstall Snow Leopard?
    In order to do that, you need to erase your hard drive - you cannot go back to an earlier system without erasing. Make sure you back up your files first. Then insert the Snow Leopard install disk, and restart while holding down the C key. If that does not work, insert the install disk, go to System Preferences > Startup Disk and highlight the install disk > click on restart.
    Once you are booted into the install disk, go past the language selection and then to Utilities in the menu bar. Use Disk Utility to repair the drive (just in case), erase it and then install. After that, eject the disk and update to the latest 10.6.8.

  • Disc repair error "couldn't unmount disc"

    Hello alll! I would very much appreciate any help from anyone!
    A few days ago I had reason to believe that I got a virus on my Macbook Pro. My hard drive might have been corrupted. I was unable to turn on my MacBook, with the screen frozen on the opening apple logo for hours. Not being tech-savvy in the slightest, I decided to simply erase my "Macintosh HD" disc in Disk Utility (restarting computer, holding down alt key) and then restore my Macbook with a recent back up that I have on an external hard drive. After erasing my disc, when I try to restore with my backup, my "Macintosh HD" disc doesn't appear. Only the "Repair HD" disk appears. I tried to repair my "Macintosh HD" disk in Disk Utility, but recieved an error message "couldn't unmount disc". What can I do to fix this? A friend told me it could be a hardware problem, perhaps a wire or something is out of place. What do you guys think?
    Any help would be greatly appreciated!

    My macbook air (OS x lion ) hard disk got crashed. now it starts with a grey screen and MAC OS X utilities. in the disk utility, the hard disk icon became inactive. when i erased the disk it became active again but i am still not able to partition it. it showed -- "Partition Error". "Couldn't unmount disk". now the disk icon became inactive again. when i click on mount it becomes active again but partioning is not done after many attempts.
    another problem: - when it I click to proceed with the installation (still unpartitioned) it verifies my macbook's eligibility and says that the machine information is not with apple. below are the screenshots.
    is there any internet issue, i got connected on my institute's wi-fi (excellent speed- 54mbps)

    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • How to do disc repair on MB

    Before installing Leopard when I get the disc from Apple store I read that you should repair the disc to prepare it for installation. How do I do this as the option for repair disc is visible but not responding when I run disc utility form the HD i the MB. I tried booting form the Tiger install disc while holdig down C key and all tis did was to ask me to install Tiger again.
    As far as I know my HD and Tiger are OK but in view of new OS I thought I should do it anyway. Any advice please or is tis al doen fir me on installing Leopard ?

    This is actually a pretty simple process...
    Stick your disc in, restart, and when restarting hold down the apple key, you will get two choices to boot from, either your hard drive or the disc you inserted. Boot from the disc. It will load up a new screen. From there you chose one of the tabs at the top and chose utility disk. And from there you can choose your hard drive and repair the hard drive. Hope this helps.

  • Disc repair states volume could not be repaired - am clueless how got here

    my disc utility repair states volume could not be repaired. I did this with Apple using my disc. Is there any options to repair other than reloading the operating system? I hate to loose all my updates and third party software.
    For half hour I have been trying to figure out how to post a question. can you tell me how I got to this page?
    Thanks
    Jackie

    Hello Jacqueline, welcome to Apple (user to user) Discussions
    The first thing I would do is back up all vital data, iTunes folder, your username/Library/Mail and username/Library/Safari folders.
    Next I would copy all passwords, network login info, mail login, third party passwords etc. You can copy third party apps as well, but it's best to use original sources if possible. Some copy protected apps can only be reinstalled via disks.
    Once you have all your data backed up, use a blank external drive, repair your disk permissions and use a copy of Carbon Copy Cloner to clone your buggy boot drive to the external as a extra precaution. You can hold option and boot from this drive in the future after you have rebuilt your present drive.
    Now once your data is safe, you can choose to mess around and try to fix your buggy boot drive with Disk Warrior, but it might not fix your problem and cost you a pretty penny to try.
    My advice if you have followed the steps above, is to simply hold c and boot off the Tiger installer disk (not the Tiger over Panther upgrade disks) and select Disk Utility from the installer menu. Select your buggy boot drive and Erase with the option to Zero. This "low level format" will take some time and ensure you get a drive that's more reliable, (hardware malfunctions is another thing obviously) from bad sectors on the platters. (a problem Disk Warrior can't fix)
    Once that's done, simply reinstall Tiger, enter your network data, go to System Preferences>Software update and repeat until it's clear. If you don't have iLife '06, you'll need to install this as it's not included in Tiger purchase disks. Update and repair permissions.
    Next it's time to reinstall apps from original source if all possible and immediately update. Reason for this is security issue in apps that get fixed, but you might have a backdoor or altered app code from a previous unfixed exploit. So a fresh copy will eliminate this possibility.
    Also be sure to visit your drive makers sites and update and driver software for Tiger.
    You can load up the rest of your files and what not, import your mail boxes, Safari bookmarks, tweak the machine the way you like it. Once everything is done, wait to see if you forgot anything, then you can always hit the clone on the external.
    Once your sure your fine, then Disk Utility Erase the clone and repeat the cloning method, using your new boot drive instead.
    Now you'll have a option boot-able backup of your boot drive in case your present boot drive kicks the bucket one morning. (It's happened to me a few times)
    Clone your boot drive before a OS update, or a major install, or whenever you wish. This way you have the option to "go back" in case something breaks with a OS update or something.
    I advise have 2 staggered clones just in case.
    So to review in short, backup, then attempt to fix, then simply reinstall to catch everything that could be wrong, then clone your drive occassionally for a alternate bootable drive.

  • Disc repair possible?

    The drives from a mirrored RAID drive are no longer mounting. I had the enclosure replaced since it appeared to be failing, but with the new box the drives won't mount. Here's the error message that Disk Utility generated. Any hope for these discs?
    Verify and Repair volume “Bandit Squared”
    Checking Journaled HFS Plus volume.
    Checking extents overflow file.
    Checking catalog file.
    Incorrect block count for file 1.shadowIndexGroups
    (It should be 8 instead of 0)
    Invalid index key
    Rebuilding catalog B-tree.
    The volume Bandit Squared could not be repaired.
    Volume repair complete.Updating boot support partitions for the volume as required.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.

    So what about the error recommendations? tried those?
    When Disk Utility fails and cannot repair, you need a good sturdy 3rd party repair tool (TechTool Pro 5; Disk Warrior 4.2; Drive Genius). In fact, I'd dispense with Apple's for repairs and just go straight to one of the three.
    Because you were having trouble before, seems like format and restore would be best, rather than even breaking the mirror and adding a new drive to rebuild with.
    Mirrors are not a replacement for mirror, and ideally would be on a bus with at least 80MB/sec or more.

  • Disc repair for Lion

    I ran disc utility and tried to verify my hard drive due to slow response times and it says the disc is damaged and I need to restart from the disc- but there isn't one when you originally download Lion from the App store.  Is there another way to verify and repair a hard drive?

  • Hard disc repair needed. how to start with the snow leopard dvd?

    Hi,
    after a check with the apple hard disc program "festplattendienstprogramm" it found an error:
    something like "invalid amount of file hard links". It suggests to boot from the installation dvd.
    meanwhile I installed mac os lion, so I've got just the snow leopard dvd and tried to boot with holding down the C key before start up sound.
    But the system always boots from the hard disc. Maybe it's a problem with the apple bluetooth keyboard?
    holding down the c key didn't work (got the bt keyboard), and mac os lion is installed.
    Sincerely
    Sascha

    - the forum ate my post -
    Summarizing:
    Backup any data that you do not have a backup of. Disk repairs are not guaranteed. They can fail or be unrepairable requiring formatting the drive and a clean installation.
    Verify the smart status in disk utility. Highlight the drive. Read the status on the bottom of the window.
    Off the top of my head, I don't know that there is a free utility to read the number of errors and how close it.
    There is a utility called smartreporter that can help keep an eye on your hard drive.
    There is no guarantee the drive is about to fail or keep going for years; but it is suspect you have to start from the install disc to attempt a repair. Could be due to improper shut down.
