Disk First Aid is stuck on Verifying volume "Macintosh HD"

Using MacBook Pro with 10.7.4 installed.
I am running Disk Utility. I Chose First Aid, selected the volume Macintosh HD, and verify...
It says:
Verifying volume "Macintosh HD"
Checking file system
The swirly bar is running in the lower right hand corner... it's been doing this for many, many hours.
What else can I do?

Perform the #4 Repair Disk function here and others as need be

  • Disk first aid

    I am new to OSX and have a question.
    I used to be able to use disk first aid to check and or repair my hard disk. I don't seem to be able to find it in OSX
    Is it called something else? and how do you use it too repair your disk? Where Is it Is it Disk utilities in the utility folder. I don't want to mess the HD up.How do you use it? What do you click on?
    Any assistance would be appreciated
    Thanks
    John

    Hi John!
    Here are instructions.
    THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
    1.Insert your Mac OS X CD-ROM disc or Restore DVD disc, then restart the computer while holding the C key. This would be Disk 1 of the 3 CD Panther set.
    2.Once started up from CD or DVD, choose Disk Utility from the Installer menu.
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
    3.Click the First Aid tab.
    4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5.Select your Mac OS X volume, if necessary.
    6.Click Repair. If DU reports errors it has fixed, then re-run Repair Disk until no errors are reported.
    7.When finished, select Quit Disk Utility from the Installer menu.
    8.Select Quit Installer from the Installer menu.
    9.In the resulting pop-up window, choose restart.
    10.After the computer has restarted, you can eject the CD.
    TO REPAIR PERMISSIONS ON THE STARTUP DISK
    1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
    2.Click First Aid.
    3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)
    Rerun RP until the only messages reported are listed in this article Spurious Permissions Errors Using: 10.3.x, authored by Michael Conniff.
    When "Repair Permissions" is complete. Quit "Disk Utility".

  • Disk First Aid Not Repairing Drive

    I need to fix an issue with my external firewire drive and I need to know why Disk First aid won't repair the problem.
    I have an IMac CoreDuo 20" 2GB RAM, 250GB Internal drive and 250GB External firewire drive (this one has the issue)
    I executed a restart on my Mac tonight and when it came back up I recieved an Invalid B-tree node size on both partitions on the external firewire drive. Can your software fix this problem? The volumes won't mount, but Disk First Aid will see them.
    Disk First Aid reports:
    Verifying volume “disk2s3”
    Checking HFS Plus volume.
    Invalid B-tree node size
    The volume needs to be repaired.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    Verifying volume “disk2s4”
    Checking HFS Plus volume.
    Invalid B-tree node size
    The volume needs to be repaired.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    Ran disk first aid. Results above. TechTool Deluxe won' t look at the external drive. The Pro version of the software repairs external drives, but their site doesn't state whether you can fix Invalid B-tree node size errors. Formatting and starting over is not an option. I have data on their in which I captured last week on a business trip and was going to back it up tonight and ironically, this happened before I could.
    I can't figure it out though. The drive didn't go through any crash or serious outage. I simply told my Mac to restart and this error appeared on reboot. I just switched to Mac as my main system about 8 months back. I have been using PC's for 20 years and never ran into a problem like this. It really concerns me that Mac file systems aren't reliable and if can't repair this, I will need to rethink whether I want to keep a Mac as my main system.
    Can someone help me with this? I sure like using Mac and hope there is a simple solution to this.
    I have tried booting from the Mac OS X cd as per Apples recomendations, but with no luck. I did use a trial copy of Data Rescue II just to see if it could see my data and it can, so I do have hope that this should be resolvable.

    You won't believe what I had to do to get back some of my files, but here goes the explanation.
    As I mentioned earlier, I used TechTool Pro 4.5.1 with no succes. I also used a tool called Drive Genius from Prosoft Engineering and it was not successful either. I did get some more error information when trying to repair the partitions with Drive Genius. Here are the messages I received:
    Error : Invalid HFS+ signature found in the volume header (0000 - (n).
    Error : Invalid HFS+ version number in the volume header (0).
    Error : Invalid HFS+ total block count found in the volume header (0).
    Error : Invalid HFS+ resource fork clump size found in the volume header (0).
    Error : Invalid HFS+ data fork clump size found in the volume header (0).
    Error : Unable to get the HFS+ volume header.
    My only other option was to purchase Data Rescue II from ProSoft Engineering and attempt to recover the files I needed. I had a bunch of recordings I had made with ProTools that I had not had a chance to backup to another location yet.
    It took a couple hours for the scanning processes and then the files were listed to recover. I selected the session folders and told it to recover. The file s were copied to my local hard drive and I was getting excited, until I tried to open one of the files. The wave files would not play and the PorTools session files wouldn't open. I was very frustrated since the file sizes seemed to be in line with the files were on the original drive.
    What I ended up doing was, using Text Edit, I opened a known good .wav file that was created with ProTools and one of the recovered files that wouldn't play and compared the headers. It appeared that the recovered file had the data portion, but not the header. I copied the header from the good file and pasted it into the recovered file and saved it.
    Was I surprised when the file played. Now, most of the .wav files I have done this with work with no problems at all. A few of the files have bad spots (bits) that added distortion to the clip, but I was able to import the files into ProTools and edit them out. It appears that the bad spots were additions to the file and did not overwrite any thing. So I just cut them bad spots out and I am going about my business again.
    The bad new is I will be spending most of this weekend manually restoring these files. The good new is that I will get them all back. There has to be an easier way to do this though.
    In Summary, the problem is not with the physical drive as a thourough drive scan says that the hardware and drive is okay. The problem lies in the Apple file system (HFS+) itself.
    I sure hope this information helps someone out there. If anyone finds an easier way to fix this, please post it here and let everyone know.

  • Powerbook G4 stopped working it cuts on but no spinning disc symbol..won't run I installed the start up disk and it starts up  but disk first aid says there is something wrong can't repair it..what do I do now? Do I erase everything and start over?

    The G4 comes on but that is as far as it goes...I installed the startup disc it started  and I  tried disk first aid but it says it can't be repaired????If I erase everything will this fix the problem as well as make me lose everything?

    Bryan,
    Do you have a second hard drive?  If you can get the install disk to boot the computer then all is not lost.  Install a clean system on a second hard drive to get back in business.  If you have any backup copies of your software and files, use them to restore your computer to good working condition.
    Then, install some form of data recovery software on your second drive.  The recovery software can look at a bit mapped version of your drive and extract data that may be scrambled but usable.  Think of the drive as a book.  If someone tore out a few pages from the table of contents or index from a book, the main volume would be there but the book would not be repairable.  Or, if the table of contents is OK but someone tore out a chapter or two, the other chapters would be there.  The book is not complete but all is not lost.
    Here is a review to get you up to speed:
    http://data-recovery-software-review.toptenreviews.com/mac-recovery-software/
    Start by getting your computer working off a clean install on a second drive so the data recovery process will work faster and have a destination for the recovered data.

  • Disk First Aid - Problem: Custom icon missing

    Hi
    Wonder if anyone can help me - my mac kept quitting out of printing photos to my Epson R300 and then froze. I didn't let it self repair once restarted but left it to do it today manually. I set Disk First Aid going and it came up with about 30 "Custom icon missing" alerts and when I asked it to repair it couldn't repair them.
    Anyone know what's happened there and how to fix it?
    I've noticed that the mac has been quitting out of programmes a lot lately but without the 'this spllication has unexpectedly quit' alert. I haven't added any new software or hardware lately either.
    Many thanks!
    iMac Flat Screen   Mac OS 9.2.x   Mac OS 9/Mac OS X Panther Dual Boot

    Vicky,
    Welcome to Discussions.
    Fortunately, the Custom Icon issue will have no impact on the general reliability of your mac.
    As a bit of background, one of the special attributes that can be applied to a file or folder (like modification date, or label, or comments, or the FileType and Creator - so a document knows which app it is associated with when you double click it) is this "Custom Icon" setting.
    So you have 30 files / folders that have been marked as having a custom icon. But when it goes to get the custom icon to display the file / folder in the Finder, it can't find it. You usually just end up with a generic icon for the file / folder. It offers no extra functionality other than displaying a pretty icon in the Finder. Similarly, when it doesn't work, you lose no functionality, other than that.
    The applications quiting unexpectedly could be an issue, but issues with printing colour photos to a printer may be memory issues. Colour photos, perhaps .jpg, are compressed. As your printer doesn't have built-in decompression software, the pictures must be decompressed on the Mac before sending to the printer. And there is the issue, if this requires too much memory, your mac can do strange things.
    Is printing from OSX any better ? I would have thought a G4 iMac with Panther would be a dream to work on.

    Santiago,
    In order to repair your hard disk, you must run Disk Utility while actually booted to the "Software Restore" disk.
    With the disk inserted, restart, then hold down the "C" key. When the installer loads, choose a language, then open Disk Utility from the "Utilities" menu.
    If you still receive an error when attempting to repair your hard disk while booted to the Software Restore disk, you must format (erase) the hard drive.

  • Install Tiger gets stuck at "Verifying volume", Disk Utility not working

    Hi there,
    I am trying to upgrade to Tiger from OS10.3.9. I have repaired the disk permissions. Each time I try to install Tiger, it gets stuck at "Verifying Disk Volume". I then booted up from the Tiger DVD and ran Disk Utility from the DVD. Now First Aid is continually trying to repair the disk, and what appears over and over again is:
    Rechecking volume.

    i don't know what to do about this. I do have two hard drives installed on my computer. The one I am trying to install on is a 74.5 GB ST380021A. The other is a 38.3 Maxtor 6E040L0.
    It would be great to know if anyone has advice on this. Thanks so much!

    hai clara,
    the issue is coz the drive on which ur trying to install has some issues .
    please goto the article http://docs.info.apple.com/article.html?artnum=13628
    in most of the cases u would try some third party disk utility like disk warrior and noton disk utility to repair the disk .
    then u need to run disk utility from the TIGER disk .
    follow the article
    http://docs.info.apple.com/article.html?artnum=106214
    to repair the disc .
    or else u can back up the data on ur HDD and then u need to do an erase and install of TIGER

  • Installed the latest Java update today on my older iMac and now it won't boot up at all. 2007 model worked fine this morning, now disk first aid say boot blocks f'ed.

    I am using an older mid 2007 imac 24 inch running snow leopard 10.6.8
    I normally accept software update recs, and today when installing the security update to java, all went fine till restart, when I got the universal "NO" sign, the circle with the line through it and just spinning gray bars underneath.
    Booted from system disks, ran first aid, said the boot block partitions or something like that needed updating but disk appears to be ok. Still not working.
    Do you think Alsoft Disk Warrior will fix? I am running off external back up drive now.
    Thanks for any help or advice. Apple as usual is as useless as tits on a bull, or a screen door on a submarine, pick your simile...

    If your backup's up to date it might be less hassle to erase the internal and clone back from the backup. Don't allow the update next time it appears - you're not the only one having problems it would seem.
    Note; the message "updating boot partitions" is a standard message that appears after a repair run. It won't go away and should be ignored.
    Provided the message "The volume Macintosh HD Seems to be OK" in green has appeared, your disc fle system is fine.

  • First Aid Services reports Errow "Invalid Volume File Count"

    In attempt to deleate a small Windows psrtition and creating a larger new Windows partition, Boot Camp directed to First Aid where the resulting error messages are "Invalid Volume File Count" and Invalid File Count",  Directions to reboot with program disks failed to work.  What next??

    What failed to work? Booting to your OS installer disk or running Repair Disk from Disk Utility when you were booted to the installer disk?

  • Disk First aid failing

    I had a printer app die on me and take the dock and the top right part of the menu bar with it (they were still visible, just wouldn't respond to any mouse clicks). I shut down every app I could (some were minimized, and alt-tab wasn't working either), then shut down the machine by holding the power button for 10 seconds (it couldn't shutdown because of the hung app).
    On reboot, it seemed to take extra long to get past the initial apple-logo spinner. Once it finally got to the login screen (the login screen shows available accounts, but requires a password), I clicked on my account, and got a beachball for an indeterminate amount of time (I walked away after 5 minutes, and came back a few hours later and the beach ball had stopped).
    Once I logged in, it slowly started, but the dock seemed to freeze again before I could get any apps started. The icons in the upper right part of the menu bar also took forever to come in (~10 minutes).
    I held the power to shut it down again, and this time booted off the osx cd. I started disk utility, and ran verify, which failed and told me to run repair, which I did. I got a ton of inode errors, and eventually, the repair failed. I tried to run the repair again, because I wasn't sure what else to do. This time, I got a ton of 'Missing thread record (id = ??????)' where ??? is a six digit number, followed by a large number of 'invalid directory item count' errors, a few other errors (incorrect number or extended attribs, incorrect number of ACLs), and another fail.
    I decided to try to mount the disk and rsync whatever I could to a usb drive, but after switching to terminal from the osx boot cd, I found the drive wasn't mounted. I went back to Disk Utility and tried to mount it, but it gave an error about the drive needing 'repair'.
    So, my question at this point is, is there any way to mount the drive so I can try to recover something?
    Also, what else should I have tried after the first 'repair disk' failed?
    Thanks

    Before I posted this, I did run through 'repair disk' three times, at which point DU gave me the amusing error message 'repair failed three times' (or something similar, don't remember the exact wording).
    That was 24 hours ago. I booted up with the osx install cd again, and this time DU doesn't even see a partition on that drive. The hard disk is listed in the left nav, followed by the optical drive, then the 'osx install dvd' partition on the optical drive, but the partition on the hard disk isn't listed. When highlighting the hard disk, all four first aid buttons (verify/repair disk/disk permissions) are grey'd out.
    Thanks
    The SMART status does say 'verified' for that disk, so I assumed it wasn't a physical failure, and I should be ok to reinstall.
    I'd love to know what happened, but I'm sensing at this point I'm severely screwed and need to reinstall. I'll wait another 24 hours before I do so, in the event anyone has another suggestion as to what I could do to find out what happened, or attempt to recover some files.

    2. If so, is it ok to just reinstall system and everything from qrecall or will it be better to start over from 10.5 Install Disks?
    You need your system discs to install the OS. However, that process includes options for importing data and settings that will vary depending on how the backup was made.

  • I get the flashing question mark on my G5/10.5 system. When I booted up on the install disc and ran first aid which failed and stated "Volume check failed Error -9972 Vol 1 could not be repaired. What to do next? Do I try the hardware diags first?

    I've never had to reload the original software and would like to avoid it unless absolutely necessary. Anyway any comments on what i should do next?

    HW Diags aren't likely to help.

    You must repair the HD,  if Disk Utility or fsck should fail to repair it, your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from if you don't have another boot drive...

    Your best bet is DiskWarrior, you need the CD/DVD though.

  • Grayed out repair permissions in disk first aid

    on a large external drive which once was read/write is now read only in 10.5
    permissions read:
    user(Me) Read&Write - false info
    (unknown) Read&Write
    everyone Read&Write - false info
    ignore ownership is checked
    the internal and system drive appear clean of this issue
    other posts mention how directories within the internal get this bug but it seems no one is having an external permissions issue.
    i am.
    i've tried:
    disk utility but repair permissions is grayed out for that drive whether from the install disk boot or the internal.
    various unix solutions but all return a "denied" statement
    creating accounts with a 80 GID as well as assorted system and admin groups
    attaching the drive to a mac running 10.4 but permissions arent accepting changes there either.
    now i know some of you are thinking back off the drive and initialize it.
    you're right but it is sizable and would be costly in time and hardware to manage that.
    so it seems a matter of running a repair on permissions would be best...
    but how to enable the option?

    In general whatever the problem it is NOT a good idea to run DU file permissions on an external drive. Permissions only apply to the active OS on the active drive.
    If the external drive is a bootable system, then you can run the proper DU on it, but only when it is the actual system.

  • Using First Aid in Disk Utility

    I have done the first aid in my disk utility after I had an issue burning a dvd and the help guided me to doing a first aid. This is the following message I received:
    Verifying volume “Macintosh HD”
    Checking 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 needs to be repaired.
    Stopped by user
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    I tried repairing it and it would not. I googled different problems and saw that buying disk warrior would help repair it. My question is: Is this a big problem that it is identifying the "HPS needs repair"? I just don't know why I would buy something to fix something when I don't know if it really needs fixed. How big is the problem? I really am not having any trouble on my computer. Please help!

    Rebooting from your install disk will not disturb anything. Reboot from your install disk holding down the c key until the Apple logo appears and the gear is moving. Choose your language from the dialogue box and go to Utilities in the menu bar and choose Disk Utility. Click on First Aid, highlight your drive in the left-hand column and then hit Repair Disk.
