"Repair Disk" option in Disk Utility need to repair drive.

I have a Seagate GoFlex Desk 2TB external hard drive. I use it as a backup drive for Time Machine. When I plug it into my iMac it dosen't open, I opened Disk Utility and clicked "Verify Drive" and then I got this...
I have backups on this drive. If I click "Repair Drive" will I lose the data on the drive?

After I Repair the drive this is what I get...

  • HT203176 i have a slow macbook, i ran live disk utilities and said I need to repair disk from a cd. did that, I got volume repaired from the external disk. when I reboot from hdd, then run disk utility, I get the same error message i did b4 repair

    i have a slow macbook, i ran live disk utilities (from hard drive), turned out I needed to repair disk from a installation disk. Did that, I got the volume (Hard drive) repaired from the installation disk disk. To this point, great!
    When I reboot from hdd, then run disk utility, I get the same error message i did b4 repair. I went thru two rounds of this.....
    Can anyone help? thanks

    Sorry guys, I don't see how to reply to you so I use reply to "me" basically.
    So the error I get is "volume header needs minor repair" and then you need to perform repair from the installation disk message.
    I did repair not verify from the disk twice. Every time ending in the "the volume had ha been successfully repaired". Then I reboot from the internal disk. Run disk utilities from it, do verify and get the same error message I got before repair. I hope this can shed some light fr you guys. Sorry I didn't include details in the original
    MEssage.

  • What are my options when Disc Utility says my hard drive is failing?

    Before I upgraded to Tiger on my G4 (this morning), I ran Disk Utility, repair permissions. After the Tiger installation, I ran Disk Utility again and got the message that my hard drive is "failing" in red letters, something I have never seen before.
    I started up with the Installer Disk and tried to run Disk repair from that, but the red remains and I am prevented from doing a repair.
    What are my options?
    (I added this question to another thread, but got a little confused about the answered/not answered option when my message was not accepted as a "not answered." Anyway, John Huber1's response to my original question was helpful. I thought it was better to start a new thread.)
    Thanks,

    Hey, guys.
    I ran into a problem this morning that I've never ran into before and I wasn't sure where to write it but I thought this is best.
    Here it goes...
    Last night I had a power surge and when I restarted my computer, my external hard drive did not mount on my desktop. I than proceeded with restarting my computer, I relinked all my connections and I cant seem to get it fixed. I have a lot of material on my external drive that I dont have backed up (I know, a stupid move) anyways, I dont want to lose that information. Also, when I open up disk utility, the icon for my external drive is there and the partition I made for my external drive shows up also but the title of my partition for my external hard drive is not in bolded font. I tried to click the button to mount my external drive cause the specs tell me that it is not mounted but when I press the mount button, it does nothing. I than tried clicking the unmount button and than restart my computer and still nothing.
    What problem am I facing and how can it be fixed?
    Thanks.

  • Disk Utility can't repair disk

    Hi, I just saw that the amount of memory left on my HD just dropped around 60GB, so I used the "Verify Disk" option on Disk Utility, and the output was:
    Verifying volume “Macintosh HD”
    Performing live verification.
    Checking Journaled HFS Plus volume.
    Checking extents overflow file.
    Checking catalog file.
    Checking multi-linked files.
    Checking catalog hierarchy.
    Checking extended attributes file.
    Checking volume bitmap.
    Checking volume information.
    Volume header needs minor repair
    The volume Macintosh HD was found corrupt and needs to be repaired.
    Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
    I don't have the disk right now, so is there some other way I can repair it, get another install disk, or anything else? I've been thinking of booting up with a Linux livecd, but can it access the HFS+ filesystem?
    Thanks.

    Try this: from http://support.apple.com/kb/TS1417
    Start up your computer in single-user mode to reach the command line.
    Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
    At the command-line prompt type:
    /sbin/fsck -fy
    Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
    ** The volume (name_of_volume) appears to be OKIf fsck found issues and has altered, repaired, or fixed anything, it will display this message:
    ***** FILE SYSTEM WAS MODIFIED *****
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    When fsck reports that your volume is OK, typerebootat the prompt and then press Return.
    Your computer should start up normally and allow you to log in.
    If you can't find your original install disk, you could always buy another Snow Leopard disk. It's only $29.

    The installation DVD is from another Mac, but is also Mac OSX 10.6
    Is it required that I use the exact disk that shipped with my computer? (Go figure, it's in Minneapolis, I'm in Atlanta...).
    The DVD however is in no way scratched or dirty. I will run the hardware test and report back.
    Thank you for the leads.

  • Macbook Pro not booting after update. ''Disk Utility can't repair disk''. Help needed!

    I have recently updated my macbook pro as I had some pending software updates. I left it to do the job over night and the next day I noticed it was not letting me sign in to my account session as usual.
    I restarted the computer and ever since then when I boot it, it just shows the apple grey screen with a bar that loads to about a 3rd and then it turns off again. I have contacted apple but they were unable to help me with this.
    So far I have tried to:
    1. Re-install OS X 10.8 - but it says the disk is locked or OS X cannot be installed on Recovery HD.
    2. Verify and Repair the disk and I errors but it cannot fix them. Some are:
                   'invalid leaf count''
                   ''missing thread record''
                   ''incorrect number of file hard links''
                   ''overlapped extent allocation''
              and it finally says ''the volume Macintosh HD cannot be repaired'' Error: ''Disk Utility can't repair this disk.. disk, and restore your backed up files.
    I would like to know a way to back up my files so that i can completely restore the disk without any data loss as I havent backed up for a while!
    If anyone has any solution to this issue it would be much appreciated!

    I just ran the Disk Utility, and cannot very disk. It gives me an error message;
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    and when I run the repair, this is the message:
    The volume GERRARD could not be repaired.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    1 volume could not be repaired because of an error
    Repair attempted on 1 volume
    1 volume could not be repaired
    Prior to running Disk Utility, I have already tried DiskWarrior, and could not repair my disk. Anyway I can fix this problem??? Formatting the disk would be my last option (though I am unsure if it will fix the problem). Any advise would be greatly appreciated. Meanwhile, I will continue to back up my file, and delete unused data and try to run it again.
    Thank you all very much for any input.
    Cheers,

  • Disk Utility - Can't repair Disk - Help needed :(

    Hi,
    I have some trouble to use Disk Utility (on my iBook G4 - 1.33 Ghz+1 GB RAM)
    I run Disk Utility to verify and repair permissions, which worked, and then Verify Disk. HEre is the logged result:

    I retried today, and now the Verify Disk task won't even work, blocking Disk Utility (needs force quit)
    (E=G4 is the name of my Hard Drive on the iBook)
    I also tried TechTool Deluxe coming with Applecare protection plan, but TTD can not check the "Volume Structure".
    Has anyone got any tips or sequence to solve this?

  • Disk Utility says I need to repair disk

    My computer is running a little sluggish so I went into the Disk Utility and selected verify disk. I got the message below. I inserted the OS X disk but the repair disk option wasn't available. I bought the computer with Panther and got Tiger later, unfortunately I don't have the Tiger disk. How do I fix this problem?

    If you are running Tiger, you need the Tiger install disc you purchased in order to run Disk First Aid repair.
    And withhout your Tiger install disc, you cannot perform an Archive & Install retaining Tiger, etc. so bad move not keeping this in a safe place.
    Your only other option is running fsck.

  • Disk utility can't repair disk, back up and restore files......I need help, I'm worried I'll lose all my photos, files etc

    Mac started hanging up while streamlining a kids show. Restarted and got the screen with the apple and the circle. restarted with control-option p and r. Ran disk repairitem got the following results;
    invalid index key,
    it rebuilds catalog b-tree,
    volume repair complete,
    updating boot support partitions for the volume as required,
    Error disk utility can't repair disk
    I'm then prompted to back up all files, reformat the disk and restore backed up files.
    Obviously need help here as I think I'm in danger of losing my files, photos etc if I don't do this right.
    Can anyone help
    Steve

    You might want to back up the disk as soon as possible, do the repair, then back it up again. First time will have the issues that Disk Utility can't fix, however, you'll have the data saved.  Then, once you get things repaired, make a new backup, and go from there.
    If you're going to use a hard drive directly connected to your iMac for backup, this is what I mentioned earlier: http://twelvesouth.com/products/backpack/ Great way to use space behind the iMac without adding something else to the desk top. You can buy it through Apple online/stores or Amazon, and there are probably other sources too.
    For external hard drives, I like those sold by OWC at http://eshop.macsales.com/shop/firewire/ as many of them use Oxford chip sets, wihch work well with macs (I've used several for years with no issues). Most pre-packaged drive/cases have a 3 year warranty, although you can buy a case and add your own hard drive. I like Western Digital Scorpio Blacks that have a 5 year warranty.

  • Power outage. AEBS says repair is needed but disk utility can't repair it??

    This happens every time the power goes out. I would wake up and my airdisk would no longer mount. It says it needs a repair (256 error). I plug it into the MB and it says it's in read-only mode. Also, disk utility cannot repair it; says there's a filesystem verification error or something.
    What the ****? Why can I never seem to repair this drive when the power goes out?
    Would disk warrior be a good investment? I could repair the disk before I upgraded from Tiger, but I cannot seem to repair it using disk utility in Leopard. Anyone have an idea? Thanks.

    My AEBS has been working fine with the newest firmware upgrade in regards to the disk utility. However, the other day I was doing some cord management and accidentally unplugged my AEBS. Ever since then I have been unable to get my USB Hard Drive to mount.
    Originally, I was getting an error stating that the disk was in need of repair, and that it could not mount the volume. I read on another one of the threads that another person was having a similar issue, and what he did was disconnect the USB drive from the AEBS reboot the AEBS. Plug the USB HD into his Mac, run a disk repair, and then renamed the USB HD, so from going to something like HardDrive to WiFiHD, ejecting it from the Mac, and plugging it back into the AEBS and it worked fine.
    Well granted I tried that. Now I am no longer getting any error on the AEBS, now the issue is on the MacBook when I try to mount the drive I get an error saying: Could Not Mount The Volume "HardDrive" where "HardDrive" is the name of the volume. So I am thinking that my AEBS is working fine now for the disk utility except that either my MacBook or my AEBS is still trying to mount the HD under the old volume name and not the new drive name. Does anybody know where that information is stored or where I could possibly access it to change it?

    LaCie doesnt make ANYTHING.  It contains a Seagate 3.5" 5400RPM HD.
    Check the HD on another computer, if nothing, your SATA bridge is fried, or the HD (very unlikely since its a Seagate inside)
    Youd have to crack open the HD, remove the SATA bridge cart thats plugged into the HD and put the HD into an enclosure or a HD dock to get the data
    those external HD use a 50 cent SATA bridge famous for failing.  The curse of all the good HD externals is the junk 3rd party SATA bridges attached to them that crash and burn.

  • After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

    After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it. See below for how to clone a drive.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

  • I can't burn a dvd using any method, Idvd tells me that my super drive is missing, dvd studio pro quits when i click burn and disk utility keeps spitting the disk out when i click burn and enter the disk??? how do i repair my superdrive for imac

    I can't burn a dvd using any method, idvd tells me that my super drive is missing, dvd studio pro quits when i click burn and disk utility keeps spitting the disk out when I click burn and enter the disk??? how do i repair my superdrive for imac, or how do I do whatever I need to do to get it working: I have already tried using a lens cleaning cd and also restored my nvram or something i forget what it was called but i restarted my computer holding down  command+optoion+p+r and still nothing???
    Free solutions are the best, although if I have to pay I will, I would prefer to not have to buy an external burner if possible and already know that is an option so please don't give me that answer... thank you for any help you can give

    Unless your iMac is still covered by AppleCare, get an external DVD burner.
    You can get perfectly good ones from Amazon for less than $40.

  • Disk Utility can't repair TM backup disk

    Hello all
    Recently, my external backup disk (a 750 GB WD My Passport) that I use with Time Machine has been acting up. At first, it wouldn't show up on the desktop, but was being recognized in Disk Utility (with the "Time Machine Backup" partition greyed out). After multiple restarts and unplugging/replugging the hard drive, I finally got to be properly recognized, i.e. it showed up on the desktop with the proper Time Machine hard drive icon. So I thought the problem was gone and started a routine backup. However, Time Machine returned an error:
    "Unable to complete backup. An error occurred while creating the backup folder."
    I search the forums, and followed the advice here: http://web.me.com/pondini/Time_Machine/C10.html
    I tried repairing the disk, but DU couldn't repair it:
    Verify and Repair volume “Time Machine Backups”
    Checking Journaled HFS Plus volume.
    Detected a case-sensitive volume.
    Checking extents overflow file.
    Checking catalog file.
    Incorrect number of thread records
    Checking multi-linked files.
    Checking catalog hierarchy.
    Checking extended attributes file.
    Checking multi-linked directories.
    Checking volume bitmap.
    Checking volume information.
    Invalid volume file count
    (It should be 3991498 instead of 3904049)
    Invalid volume directory count
    (It should be 678218 instead of 673790)
    Invalid volume free block count
    (It should be 9588404 instead of 11784378)
    Volume header needs minor repair
    The volume Time Machine Backups was found corrupt and needs to 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 now I'm still following the advice on the above mentioned page by posting on here. Any help at all would be greatly appreciated. I am using a 2010 15in 2.66 i7 MBP, if that makes a difference, although my guess is the problem's with the harddrive itself. I think there may have been one time about a month ago when Time Machine stopped responding (or something like that) which forced me to pull out the harddrive, possibly corrupting the data. But I'm not sure, and I do recall making at least one successful backup after that. Well, actually TM confirms this: "Latest successful backup: 5/27/11 at 11:51 PM". So I have no idea what's going on. Again, any help would be appreciated.

    You can't tell what's corrupted or where.  Time Machine backups have a very complex structure, all linked together.  So, you can often do new backups, or restore individual items, or even entire backups, as long as you don't stumble over the damage.
    There's a chance a heavy-duty 3rd-party disk repair app, such as Disk Warrior, can repair them.  It's about $100, and probably a good investment for the future, but there's no guarantee it can fix them.
    If not, or if you don't want to spend the money, your only option is to erase the disk and let Time Machine start fresh.
    It sounds like you may have other data on it; if that's in the same partition, that's not a good idea.  This is a good time to copy the data off, erase the disk, and make 2 (or more) partitions on it, so Time Machine has its own, exclusive space.  See #3 in Time Machine - Frequently Asked Questions for details and instructions.
