Help with Disk Utility and disk repair
I just ran disk utility to verify my hard drive and the report says this:
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 The volume sh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
After saying that HFS volume needs repair, it won't let me repair the disk. That button is grayed out in disk utility. If I boot the computer from my OSX install cd and repair it that way, will it erase all of my data on my hard drive? Any ideas?

To repair a startup volume you must boot from your OS X Installer Disc:
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.

Disk Utility and Disk Warrior error on internal hard drive....PLEASE HELP!!
After running idefrag on my internal Western Digital 120gig hard drive. The drive did not appear after I rebooted my mac. I opened Disk Utility and the drive is there but grayed out. I used "repair disk" under First Aid and it gave me this error:
Verify and Repair disk “HD 120”
Checking HFS Plus volume.
Invalid B-tree node size
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Then I tried using Disk Warrior 3.0 to rebuild and it gave me this error:
error ""WD 120 GB" cannot be rebuilt. The original directory is too severely damaged. The disk was not modified (2155, 2179)".
I'm not sure if this is the right area to post this, but I need help as most of my important data is on this hard drive. What else can I do?
I am on a g4 quicksilver with 10.4.3 installed.Sorry to hear about your problem but unless you are working with very large files such as with video editing, etc., using a defrag utility is not required with OS X and no defrag utility should be used on a hard drive without a backup first.
The current Disk Warrior version for Tiger is 3.0.3 and if Disk Warrior cannot repair the drive/directory, it must be in bad shape which was caused by using idefrag.
You can try using a data recovery utility such as Data Rescue (Prosoft Engineering) which includes a free trial version. -
Disk Utility and Disk Repair function
I ran the "Verify" function on the hard drive and came up with an Error, but can't figure out what to do next. The option of "Disk Repair" is grey. I found an older discussion about the specific error message - "Incorrect size for file YellowPushBtn_Pressed.tiff (It should be 0 instead of 5602)" This older discussion lead to the QuickTime application, but I was unable to local the file they talked about.
Any ideas on how I should proceed from here?
ThanksDisk Utility won't repair the drive if that drive is the one from which the computer is currently booted. The usual thing to do is boot from the installer disc. I don't know about the shift key; I thought it was holding down the C key to boot from an optical disc.
What holding down the shift key does is boot you to safe mode which reduces the number of things running to a minimum. I have found that while you can verify a boot drive you can get errors and an analysis from safe mode reduces this likelihood.
*General Instructions*
Boot from the installer disk, select language if applicable, choose utilities, run Disk Utility and verify (and repair if necessary) the drive. You can verify a drive from DU on your main drive while booted but I have found this can result in incorrect reporting of errors. To repair your drive you have to run it from a drive other than the boot drive anyway.
Next, boot from your drive in [Safe Mode|http://docs.info.apple.com/article.html?artnum=107393] and repair permissions. You can repair permissions while booted from the installer disc but this uses the permissions configuration on the installer disc which may be out of date if you have run any updates on your computer. Booting your computer to Safe Mode restricts the number of things running on your computer while permissions are being run and does a bit of spring cleaning at the same time.

From BDaqua (couldn't have said it better):
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again 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.
6. Click Repair. Disk Utility checks and repairs the disk.
Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes." -
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 - Won't Repair Flash/Thumb Drive
So my Mac froze for some reason, while my Kingston thumb/flash drive was in. I tried to eject it, but I could only force eject (which it said may cause issues). After that, whenever I put the thumb drive in, it said something like the drive won't work and I had to copy the files to my desktop. When I go into disk utility and click repair disk, it says this: "Disk Utility stopped repairing “UNTITLED 1”: 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."
I can't erase the thumbdrive, because it says I need a source, which I don't know what that means.
Can anybody help? The files are useless now as I have transferred them to a CD, so I'm fine with erasing the whole thing. And yes, I know I can get a new on at any store for cheap, but I'd like to know if this can be repaired. Thanks.You haven't mentioned how the thumb drive was formatted to begin with; is it GUID partition map and Mac OS Extended (Journalled), or is it FAT 32 with MBR partition map?
If it's the latter, DU can't repair it, but should be able to format it. However, the forced ejection may have damaged the file system to prevent that.
If it's FAT32, re-format it on a PC and try again on the Mac.
If it's Mac formatted, you could try erasing and reformatting on another Mac (or as Hackintosh says, from the DVD), but if that doesn't work, try the PC route; reformat to FAT32 on a PC (if the PC will recognise it - thay don't always), then go back to the Mac, repartition and format.
If that fails, it's recycling fodder. -
someone pls help me
Well there is Resolve startup issues and perform disk maintenance with Disk Utility and fsck witch includes step by step instructions to run disk repair without the install disk.
But before doing that, it's a good idea to backup. You may want to troubleshooting your superdrive / disk before hand. if I disk repair fails you may need the disk working to re-install the OS.
Dose the computer read any DVDs? if no, you may want to use Troubleshooting the slot load optical disc drive. -
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
SteveYou 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. -
my 3 year-old macbook pro is very slow. I have run disk utility and virus scan with no improvement. The "beach ball" will spin for minutes at a time when opening, closing or changing windows. Apple Store looked at it a few months ago with no help. What can I do?
Under CPU: 3.5% user; 5% system; 91% idle; 441 threads; 90 processes.
Under System: out of 2GB - 54.7MB free; 530MB wired; 603MB active; 862MB inactive; 1.95GB used.
Is too much of the system memory tied up? If so, what can I do to free some up? -
Can I fix a disk with this message?
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.Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas. -
Yesterday I ran Disk Utility and came up with hundreds of permissions that needed repair. I hit the "repair permissions" button and waited until it said they were repaired, but just for fun I hit the "verify permissions" button again, and they all came back! I did this several more times and every time I would hit "verify permissions" I would get the same list. What's up? I've always suspected diagnostic programs, but this is Apple's own!
Ignore them. They aren't errors. You will keep seeing the same ones. As long as you get the message "Permissions repair complete," you're OK.

Need assistance with my Porsche Design LaCie Time Capsule... It is not operating at all.. I have ran the diagnostic via the Disk Utility and under the error reading it runs the repair and then says it not about to repair what do I do... Thanks
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.

In reference to question the computer gave no warning but lost internet connectivity. I shut down for a while and when returned it would only boot to gray logo screen with spinning gear. Ran disk utility and on Mac HD drive it stopped after "Updating boot support partitions as required". Then in red: Error: Disk utility can' repair this disk ....disk, and restore backed up files. I'm running OS X 10.8 and had just updated the iOS about three days ago. Not familiar with reformat process on MacBook Pro and would like some ideas whether I should go to the Genius Bar here in Sydney or try it on my own. I have been using time machine to back up to a 1TB La Cie drive right up to the crash. Thanks for any advice.
Well it turned out the drive was shot. Took it to the genius bar yesterday and they ran a test on the drive before trying the restore routine again. Drive failed.
Replaced the drive and got the MBP back today. Pretty quick and decent service once you get an appointment.
Now having trouble figuring how to do the Time Machine saved files. Have several applications which I'd like to keep but not sure how to trans the apps from my backup to the new. Hunting for answers on that on the web.
Thanks for you help, Eustace. -
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 and repair permissions problem after upgrade 10.5.1
*Problem with Disk Utility* - +repair permissions don't work anymore+
After upgrading to OS X 10.5.1 tried to correct permissions with Disk utility. But I'm not able to repair permissions, because I get this message every time "fault: The underlying task reported a fault at concluding." and permissions repair stops. Has anyone else had this problem and does anyone have any idea how to get this working again?Will try installing OS X 10.5.1 again from the downkoad that you recommended. Won't be able to do this untill after the New Year but I'll let you know if this helped. I had another problem after he 10.5.1 upgrade and that was that the Security update 2007-009 also refused to install. Could this be related too the problems with Disk utility and the permissions problems.

i used the "erase free space " option in disk utility and now my imac says the disk is full and wont let me download songs. please help!
You could try repairing permissions with disk utility, I don't think you will have the option to repair the drive but you could verify it.
This may help you delete the files that DU made but did not remove when erasing the free space.

When you get your SL disk it will not have the iLife applications, that would have been on the second install disk that should have been with the computer. I forget which version of iLife you will need for SL but I think it is this http://www.amazon.co.uk/Apple-iLife-Single-User-Mac/dp/B003XKRZES/ref=sr_1_1?ie= UTF8&qid=1409607702&sr=8-1&keywords=apple+ilife+11
A search of the forums will confirm or deny this.
As to whether a clean install will cure your problem, i.e. partition the HDD and install I would expect it to be yes, but there are no guarantees it is an old machine.
