bob:
Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory error which Disk Utility cannot repair.
•I suggest you read through the article.
•Then, if you do not have an up-to-date backup, it will be a good idea to try to save as much as you can of your data.
•The article suggests using a third party utility. Disk Warrior and Tech Tool Pro are the best utilities for this job. You will need to get one of them and run it, by booting from the CD, or installing it on an external firewire drive or on a second Mac which you can then run in Firewire Target Disk Mode.
Please do post back with further questions or comments.
Good luck.

  • "Volume needs Repair" -Disk Utility--what do i do?

    So, my computer was freezing & I had the insight to run Disk Utility on the Repair part, everything comes up great, but on verify, under "Network"--Volume comes up needing repair. I looked it up under About the Mac & see that Volume is empty of info. Here is the report:
    "Checking volume bitmap.
    Volume bit map needs minor repair
    Checking volume information.
    Invalid volume free block count
    (It should be 3922629 instead of 3922551)
    The volume Macintosh HD needs to be repaired.
    Error: The underlying task reported failure on exit"
    Don't know if it matters but the indented portions of the report were in red, otherwise, in black.
    What exactly am I to do with this information? Thanks!

    In this instance, "Volume" refers to the hard drive. (I quizzed my fiancée - she thought of speaker loudness too... )
    10.1, 10.2 etc is the Mac Operating System version number. (ie My eMac is running Mac OS 10.4.9)
    If you flip down the CD/DVD drive door on the front of your eMac, there is a sticker that has the serial number, a barcode, then a series of information.
    In my case:
    1.25G HZ/512MB/160GB HD/DVD-RW/CD-RW/56K MDM
    Which means
    1.25 GHz processor
    512MB of RAM
    160GB hard disk drive
    DVD & CD burner
    56k modem
    Note that the "160GB" drive actually only holds 149GB of data - and will show up in Disk Utility as such, because of the difference between binary and actual bit sizes... (check out wikipedia...)
    When looking at the list of drives to examine in Disk Utility, the internal hard drive will show up as "internal" in the list of attributes at the bottom of the page... (ie when you click on it, it then shows you
    Disk Description - ST.......
    Connection BUS - ATA
    Connection Type - Internal
    Connection ID - Device 0
    SMART status should "work" (ie tell you if the drive is good/bad) because you're looking at the internal drive, not an external one.
    All that said and done... I still strongly suggest looking inside the eMac's inspection hatch on the base of the computer... if your eMac is freezing up for no apparent reason, it's much more likely to be the capacitor issue than an error found by Disk Utility...

    Volume needs repair " I have my Tiger Update disk but it will not bootup from it - not sure why? I do have my old install disk form my old iMac Version 10.1 - can I bootup from this disk and try fixing the issue? I would rather download something that's not expensive or free to help fix the issue. Any and all HELP would be GREAT!!!! THANKS Scott

    Because the new software is insane. If there is a leading space on a line the line gets deleted. There's more insanity as well, but I would guess that's the problem with your post.
    Anyway, your problem is that there is minor damage to your startup disk, which can probably be repaired. However, you can't repair the disk while booted from the disk. Boot from your install disk, then go to the menu and find Disk Utility there and use it to run the repair function, then reboot. If Disk Utility still can't repair the damage you need to buy a copy of Disk Warrior and use it.

  • 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.

  • DiskWarrior and Disk Utility can't repair volume after 10.4.6 upgrade

    I appreciate any advice on the following problem:
    After installing the 10.4.6 update On April 4 (which installed just fine), I did my usual post-installation system maintenance including repairing permissions, running CRON scripts and cleaning the caches. I got a strange Apple Script error that flashed on and off the screen (too quickly for me to document) while I was cleaning the caches, then the process finished. Then when I used DiskWarrior as part of my usual maintenance, it "stuck" while saying that the process was slowed because of a disk error. I waited for an hour, and it never completed. I then restarted using the OS install disk, called up Disk Utility and selected Repair Disk. This is what I got:
    Verifying volume "Macintosh HD"
    Checking HFS Plus volume
    Checking Extreme Overflow file
    Checking Catalog file
    Invalid node structure (in red font)
    The volume Macintosh HD needs to be repaired (in red font)
    Error: The underlying task reported failure on exit (in bold red font)
    1 HFS volume checked
    Volume needs repair (in bold red font)
    I cannot repair this problem using either DiskWarrior or the OS installer disk with Disk Utility. In addition, I was unable to archive & install the system while using the OS install disk! I have tried repairing permissions and using DiskWarrior and the OS Installer disk again with no success.
    I am able to work on my Mac, but things seem slower and I get occasional oddball errors that make no sense. A few times, applications have quit unexpectedly when they weren't before.
    Am I going to have to initialize the hard drive and reload everything?
    Many thanks!

    Mac G5 (dual 2GHz)   Mac OS X (10.4.6)  

    I had a similar experience after installing 10.4.6.
    The messages I got in Disk Repair were:
    Checking Catalog file.
    Illegal name (in red)
    Illegal name (in red)
    Keys out of order (in red)
    The volume Rich's HD could not be repaired. (red)
    Error: the underlying task reported failure on exit. (In red)
    After a long time on the phone with Apple, we decided to reinitialize the hard drive. I have reinstalled the OS and am in the laborious process of restoring my user files and non-Apple applications. What a hassle! And I am not even sure all will be restored to proper functionality.
    Don't know if either yours or my disk failure are related to 10.4.6 but Apple better watch closely for user feedback. These are potentially disastrous problems for users if they have not backed up.

  • 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.

  • 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

    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.

    I wanted to run Disk Repair, but the button would not highlight, therefore could not be started.
    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?
    Thanks in advance

  • Disk utility unable to repair disk. What next?

    Disk utility unable to repair disk. What next?

    I encountered the same problem. After verify disk, I got the message to repair the disk. But it was unable to complete the repair. Rather than purchase Disk Warrior, I tried something else.
    What I did was reinstall the OSX (this iMac is still on Leopard). I backed up everything, naturally, before doing the reinstall. I chose the "Archive and Install" option, along with "Preserve Users and Network Settings". This method moves  existing files to a folder named "Previous System" and imports existing user accounts, network settings, and home folders into the new OSX.
    After the successful reinstall, I ran Disk Utility. It checked AND repaired Permissions. It verified that the disk was fine and no longer needed repair.
    If this didn't work, my plan "B" was to reinstall the OSX again, this time with the "Erase and Install" option. Fortunately, I didn't have to go to plan "B".

    So, you can't Install OSX to the external?
    Or you can't boot from it when you do?
    You're not the only one wondering... I'm reminded of the Goose that laid the Golden Egg story.

  • Disk Utility can't repair Macintosh HD.  What should I do?

    Here is a "quick" synopsis of what has happened thus far:
    About one month ago, my computer started getting very sluggish (ie, it would take forever to startup, would always freeze after sleep, etc.)  I lived with it for about two weeks, since it would always run quickly after waiting ~30 minutes after starting/waking up.  Eventually, this grew old.  I browsed the internet and did multiple suggested fixes (reset PRAM, run Disk Utility, ran in Safe Boot Mode, etc.).  Nothing seemed to work.  I opted to zero out the harddrive and reinstall Mountain Lion after making a backup.  That was about two weeks ago.
    Everything worked fine, up until yesterday.  Once again, things started getting slow.  I decided to shut down my computer for the night and would check it in the morning.  When I turned it on this morning, it wouldn't startup correctly.  I could login, etc., but it was frozen and I couldn't open any applications without getting the spinning beach ball.  I waited about an hour, but it was still slow/loading.  I shut the computer down and booted it in Verbose Mode.  I ran the various commands to check the conditions of my disk, but when I ran the "fsck -fy" command, I got an "I/O Error."  I then tried rebooting my Mac, but it would get to the gray screen with the apple logo and the spinning wheel, and then the progress bar would appear.  Before the progress bar did anything, it would shut itself down.
    I then started the computer up and directly went to OS X Utilities.  I went into Disk Utility and tried to check permissions and repair the disk.  Only this time, Macintosh HD was grayed out and seemed to be unmounted.  I couldn't get it to mount.  I went into the Apple Store to have them run their own diagnostics.  However, the apple store employee was unable to get the test working, so that was basically a bust.  At this point, the computer still didn't turn on.
    I got home and, just for kicks, held the "N" key while booting up my computer.  For whatever reason, my computer started up (though it took a long time and there was a progress bar).  Now, I made another backup of my disk and am wondering what to do.  I ran Disk Utility again to repair my disk, but it says that Macintosh HD is not able to be repaired.  When I checked permissions, there were tons of Input/Output Errors.  Based on my research, it would appear that I have two solutions.
    I can either purchase DiskWarrior and use that to try and solve my problem, or I could just get a new hard drive (and I would upgrade to a SSD or SSHD).  DW is about $50 if I just download it, and the hard drive would cost me $150 or so.  Since I don't know exactly what is wrong with the disk, I don't know if DW would be able to fix it.  That being said, if the hard drive isn't the problem, there would be no reason for me to purchase a new one.  I guess I would just like some advice, as to what you would do.  I apologize for the long post.
    TL;DR: Disk Utility can't repair Macintosh HD.  Should I get DiskWarrior or a new harddrive?
    Thanks in advanced!

    Most importantly, youve already backed up all the data.  All else is cake.
    A new HD would cost you only $20 more than disk warrior,....theres no reason to repair a worthless crippled HD, .....new HD 1TB is $70.
    Once you back up all the data on a failing HD, further diagnosis has no meaning,....not anymore.
    Grab a 1TB  or 750GB  Toshiba/Hitachi (both used by Apple inside their Macbook Pro nonRetina,...both are made by Hitachi)  5400RPM SATA HD.
    Forget the repair,.......repair only serves to bring a HD to a point of BACKUP.....since youve already done that, its now just wall art or trashbin fodder.
    These are the same HD used by Apple in their Macbooks
    http://www.amazon.com/MQ01ABD-2-5-Internal-Hard-Drive/dp/B0077CV2RO/ref=sr_1_1?i e=UTF8&qid=1376281905&sr=8-1&keywords=toshiba+1tb+2.5%22
    In the future ALWAYS remember to have 2 backups for everything.  2 backups is 1, and 1 is none.
    That way when something crashes (and they all do).....its no worries.

  • Mac Pro Slow Shutting down Disk Ut says needs repair

    Hi hope someone can help,

    Explanations:
    Folder Depth: This number indicates how many folders are nested inside each other. If a disk contains only three
    folders and Folder A is inside Folder B and Folder B is inside Folder C, then this disk has a maximum folder depth of
    three. Folders nested too deeply can cause software compatibility problems.
    Property List: This is a standard file format for storing data and is often used to store preferences. The names of
    these files normally end with a .plist file extension. Corrupt property list files can cause system instability.
    Resource Data: This is an older file format for storing data and was often used to store preferences. The names of
    these files normally end with a .rsrc file extension. Corrupt resource data files can cause system instability.
    System Symbolic Link Files: These are files used by the operating system that are similar to aliases. If these files are
    damaged it may prevent startup or cause system instability.

    Went back to Disk utility and now it says that my hard drive doesn't need repair! whats going on! can anyone help?!
    Thank you

    Two things off the top:
    128MB are GUID partitions that are not user volumes.
    There is also a 200MB EFI partition as well.
    Drive Genius needs to get their program updated.
    You need to work from an "emergency" boot drive to repair your boot drive, RAID or no. I hope you are and not from CD or DVDs.
    Forget about Permissions. They are very minor. They only have to do with ownership and security and based on what is in
    /Library/Receipts
    Trying to verify? all you want to do is repair and rebuild.
    If you ran DU and DW and did repair and rebuild and WROTE NEW DIRECTORY and the problem remains, erase and restore, or...
    +I am useless with RAID and have no idea...+
    Don't use it except to test, learn, experiment with. But not for system drive.
    Above I asked, "are these a matched pair of drives" ie, same make, (looks like same size), vendor, model? they should be. Less chance of trouble if nothing else.
    ON the boot volume, do a Get Info when you click on the drive, look for "Ignore Ownership on this Volume" and make sure it is NOT CHECKED. It can't be to repair permissions and be bootable.
    The underlying cause of disk errors may be marginal or bad RAM. Test those FBDIMMs. Run Apple Hardware Test and Memtest (even Microsoft uses Memtest for Vista).
    Drives rarely break. Systems do. Directory and btree catalogue and volume information blocks do.

  • 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.

  • Disk Utility can't repair this disk

    I have been having trouble booting. It started when I connected a router to it. It seemed to eat up the free disk space and I only have 77 MB left or something around that.
    Anyway, I tried deleting files with command-s commands, and it worked one time and it freed up 2 GB of space. I restarted the computer and when I tried to start it up, it still got stuck in the gray screen with the whirly thing at the bottom. I checked the space and it was 77MB now.
    I decided to boot from the Install Disk (Snow Leopard 10.6.0).
    I checked Disk Utility first and verified the disk. It came up with the message:
    "Error: Disk Utility can't repair this disk .... disk, and restore your backed-up files."
    What should I do now?
    I have the Mac HD volume on backup already so I don't have to do the back up stage.
    Should I erase the disk while I am in Disk Utility?
    And format it to Mac OS Extended Journal?
    And then install the operating system again?
    Thanks.

    To answer your questions, first, some other options...
    If you fill your disk up that far, you are going to have problems. Don't ever do this, 10% is a bare minimum, you may need even more, depending on the size of your disc.
    I have seen before where a disc repair utility couldn't perform its function simply because there was not enough slack space available on the drive. While I have never seen this with disc utility, it is possible that the disc is repairable as-is, if you could just free up a couple more gigs of space first.
    Secondly, you could also try Disk Warrior, or to a lesser extent, Techtool Pro, or even iDefrag. I have personally never had Techtool Pro fix anything that Disk Utility or Disk Warrior couldn't fix, so I hesitate to even mention it, but I have had Disk Warrior and iDefrag clear up problems that Disk Utility either couldn't detect, or couldn't fix.
    If you are still in dire straits, you should re-partition the drive using disk utility. This is the safest route, then go from there.
    good luck!
