Disk Utility - First Aid - The underlying task reported failure on exit

Disk Utility -> First Aid -> Repair Disk Permissions provides in red
Error: The underlying task reported failure on exit'
This was a nightmare for me to fix, but after I learned how it was easy. If you get this error and you have not already restarted your computer, open you sharing preferences and make sure you ahve not set the everyone group to 'no access'. If you have change it and retry to run the permissions repair. If you have already restarted you will need to startup using your install DVD and then open terminal. In terminal type the following to fix your permissions.
chmod 775 /Volumes/'Macintosh HD'
This will change your permissions and you should be able then to get past the grey screen.
Hope this helps someone.

Hi everyone, I believe my permissions are the problem.
I let someone change permission settings to share music files on their hard drive and mine and another mac (3 in total) yesterday. I seemed to work. I can't remember if I then shut down my mac or just closed it. Anyway last night I was trying to organise the music files and burn them to dvd. I also tried change the permissions as some of the files were read only. I though it worked. It seemed to be burning and the screen saver came up, I clicked to exit screen saver and it just went to black and back to screen saver and i couldn't go any further. I had to hold down the power button to turn if off.
I tried to turn it on and now it's stuck on start up gray screen with the loading wheel thing? just loading forever.
I used disk utility, verified volume and repair disk are ok, but verify permissions and repair permissions, I get an Error message "the underlying task reported failure on exit"
I opened terminal and typed in what tryjezus1 said,"chmod 775 /Volumes/'Macintosh HD'" and pressed return. Not sure if I should have pressed return or if I should have just closed the window?. Anyway I'm still stuck.
I only have the mac since march so I believe I still have phone support, but if anyone can help I'd like to try and sort this out myself.

Disk Utility issue-Error: The underlying task reported failure on exit

When I run Disk Utility on the hard drive( repair permissions/verify disk), I see an "illegal name" message and the following error message and DU will not complete the "verify disk" function.

So I decide to play around with Bootcamp for the first time, and I go through the install but it kicks me out, telling me there was some kind of HDD error. It points me to Disk Utility, and I click on Verify Disk, and then I get the following error:

So I do some searching, and Apple tells me that I need to reformat! ***?! There is nothing wrong with my HDD, or at least so I thought. No clicks, no shutdowns, nothing. Does this mean that soon my HDD might die? And if not, how the **** do I go about installing Bootcamp now?
Here's Apple's support document:

You don't need to reformat.
Put your first installation disk in and reboot, holding down the C key when you hear the chimes. When the installation program starts, start Disk Utility from the menu and select your system drive, then do a verify/repair from there.
The reason it can't repair it is because Disk Utility won't do a low level repair on the system drive in case important system files are moved. When you boot off the CD, your system drive isn't in use and can be repaired easily.

Disk Utility will not verify disk because, "The underlying task reported failure on exit." Now what?

Disk utility will not verify disk because, " The underlying task reported failure on exit." The "repair disk" button does not light up. The report says that repairs need to be made to the hard drive. I have already checked permissions. What do I do next to get the repair process started? Also, I cannot find a defragmenting drive option in Disk Utility. Doesn't it exist?

You need to boot from the install DVD (or a clone of your internal) to run Repair Disk. Repair Disk will be grayed out, dimmed, because you can't repair from the same volume you are booted from.
EDIT: No, you do not yet need to use Disk Warrior or Tech Tool or do any reformatting. These steps might become necessary only if Repair Disk fails.
Unless you have very large video files, for example, there is no need to run any defragmenting utility. OS X does it all by itself on the fly.
Try Disk Utility
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
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.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
If you don't have the install DVD, try a Safe Boot. Hold the Shift key down at startup and give it much more time to boot than usual. It's trying to repair the drive directory.

As it turns out, this didn't completely solve the problem, it solved part of the problem.
Here is a summary to the root cause of the problem.
SUCCESS...
Problem Summary : The system crashed and would hangup during boot, tried many things, until I eventually erased the disk and started over again.
iMacG5 24 GHZ Intel with One internal disk partitioned into 3 logical drives
Cub_1 OS X 10.5.7
Cub_2 OS X 10.5.7 (Carbon Copy Cloner backup of Cub_1)
Cub_3 OS X Server 10.5.7 (standard os x server setup)
At some point after setting up standard preferences, OS X Server crashed.
When I tried to restart, the machine would hang up during boot.
Finally after several attempts, ran Disk Utility from install dvd and repaired Cub_3
When I tried to run "Repair Permissions" on Cub_3 from install dvd, I got an error
Disk Utility Error: The underlying task reported failure on exit 1.
Rebooted, and started in single user mode (CMD-S) during boot until I saw the unix commands on the screen
RAN : root # fsck -fy
Then I began seeing the same command filling the screen :
posix_spawnp("/usr/sbin/mDNSResponder") could not find file or directory
Called Enterprise Support and spoke to Frank Alcorn, he said this was most likely a permissions problem and asked me to try repairing permissions from the install dvd. I told him about the error, but nevertheless I tried it again and got the same Disk Utility Error: The underlying task reported failure on exit 1..
He asked me to try booting into single user mode again, and to try
root # chmod 775 /
root # reboot
During the reboot process the machine got hung up again, and could not get the single user mode to work at all.
Frank said the command needed to be :
root # chmod 1775 /
Frank asked me if I had changed anything in file sharing, and I told him I had. He asked me what I had shared, and I said the entire drive Cub_3. He asked me what I had done for permissions, if I had denied permissions to anyone. I told him that I had set myself up as the only user that could have access to it, and when he said that's where the problem was the lightbulb went off, and it made sense.
Shortly after I set the sharing preferences is when the server crashed. It all makes sense now...
Frank said not to share the entire disk, only portions (share points) of it. I had done this in Panther Server, and Tiger Server and it worked fine, but apparently Leopard Server works a little differently, maybe more secure.
It seems to me that if sharing the entire disk, which is what I needed would cause such a problem there should have been some sort of warning from the operating system, but there wasn't. I had run into this problem several times over the past three weeks since I had started working with Leopard Server, but in each case I ended up re-installing OS X Server and starting over again.
I told him I would try to reboot from the OS X partition (Cub_1) and try it from there.
He asked me to let him know if it worked, and I said I would...
Problem FIX :
I booted back into the partition containing OS X (Cub_1) and did the following via the Terminal.
$ su - root
$ chmod 1775 /
$ reboot
During the reboot process I held down the (OPTION) key, and selected Cub_3 (the os x server partition) and sure enough after a few minutes of holding my breath the login window magically appeared. So I logged in, and did not have to re-install the server. Hallellujah....
This solved the boot hang problem. It is great to finally have an answer. In retrospect it makes sense, but that's why its hindsight...
The reason for sharing the entire disk in my mind was that since I was the only user on the system, it was easier to have one disk mounted on my workstation rather than several folders. It made sense to me, it still does. I don't need a bunch of folders, just one disk is easier...

Verify disk permissions: Error: The underlying task reported failure on exit.

I need help. My iMac has been doing weird stuff for awhile but now it's just out of control. I did a system restore from a time maching backup and I thought things were okay, but then I rebooted in safe mode just to see if it would help with the "slow" problem I had after the restore. Well, all I could get after that was a black screen. So I booted up from my install disk and ran verify disk permissions and got this error code: Error: The underlying task reported failure on exit.
I've also seen: Invalid node structure, etc.
I hope someone can give me some good advice. I've thought about purchasing Disk Warrior but am trying to put it off as I don't want to spend $100.
Thanks for any help.

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

Repairing Startup Disk: The underlying task reported failure on exit.

I'm running a G5 dual 2 ghz PowerPC with 2.5 ram with OS X 10.4.11.
A quick rundown: I've had some crashing and dropouts of apps. nothing too extreme but not as smooth as it should be. I ran OnyX (which I do every few weeks) and it found a problem with the startup disk, it needed to be repaired.
After booting from my Tiger Disc and running Disk Utilities I got the following:
- overlapped extent allocation (file 12412030d)
volume bit map needs minor repair
the volume '*' could not be repaired.
Error: The underlying task reported failure on exit.
I tried this twice, repairing permissions in between (which I later read I shouldn't have done). I haven't noticed any data loss but I'm concerned. I don't have a complete bootable backup of the drive though most of my important data is backed up on an external drive.
(BTW: I'm gunshy of Discwarrior, before that $100 recommendation is made, as the one time before I used it, about 5 years ago, it fried my OS entirely and required a complete reinstall.)
What should be my next step? Any thoughts/suggestions?

(BTW: I'm gunshy of Discwarrior, before that $100 recommendation is made, as the one time before I used it, about 5 years ago, it fried my OS entirely and required a complete reinstall.)

Repair Disk Permissions Error: The underlying task reported failure on exit

Hi All...
any idea about this error when trying to Repair Disk Permissions using "Disk Utility" :
"Error: The underlying task reported failure on exit."
No repair is made at all! It just stops right after being launched
It happens either when booting on the Leopard CD or on external FW drive...
Cheers guys!!

It sounds as if you transferred the errors when you migrated your files from the G4. Something in that old filestructure that is not right. It might be the ownership of a single file somewhere.
Have you considered DiskWarrior?

The underlying task reported failure on exit - what do I do next?

Hi,
I recently decided to verify my internal drive using Disk Utility. The programme went through the motions then I got the following message:
'First Aid failed
Disk Utility stopped verifying “Internal Drive” because the following error was encountered:
The underlying task reported failure on exit'
In the progress window it read:
Volume Header needs minor repair
The volume The volume I Drive needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I have no idea what this means or what actions I need to take next - can anyone help me out?
By the way, everything seems to be working just fine otherwise apart from Front Row which hangs whenever I try to access media

Hi there,
You need to boot from your Install disk to actually repair it.
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, 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.

5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then try a 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.

MacBook won't boot - Error: The underlying task reported failure on exit

My wife's new MacBook won't start up. It crashed earlier today and when she tried to restart it, it got as far as the gray Apple logo and the spinning gear and then it reboots again. I booted it with the Leopard install disc and two strange things happened.
1. When the installer first opens, it gives me an error that says I cannot install Mac OS X on this computer. This is a 3 month old MacBook that shipped with Leopard, but it's telling me that OS X can't be installed.
2. When I run verify or repair permissions with Disk Utility from the Leopard disc, I almost immediately get an error stating "The underlying task reported failure on exit". When I try to verify or repair the disk, it says everything is fine.
The HD appears to be fine. I can access it from Firewire Target Disk Mode and everything is still there. I can also boot into Single User Mode, but not Safe Mode.
The night before the crash I made a change to the HD permissions via "Get Info". I copied the "Read/Write" settings to all enclosed folders because it was telling me that it couldn't install Flashplayer because I didn't have sufficient permission, even though she has an Admin account. After the change, Flashplayer installed just fine and everything was OK until this afternoon when she had a kernel panic while iChatting. iChat was the only program open at the time. She rebooted and hasn't gotten past the gray Apple logo since. I read in some other threads about people having the same issue after accidently setting HD permissions to "none". One suggestion was to use Firewire Target Disk Mode to open the drive with another computer and change the permissions back. I tried that, and the drive opened just fine, as I mentioned, but the permissions didn't appear to be set in a way that would cause problems. I set all of them to read/write and applied them to all enclosed folders just to be sure, but nothing changed when I rebooted.
Any other suggestions will be much appreciated. Thanks!

When I looked at the permissions for the HD in FW Target Disk mode, it was set to:

Everyone: Read Only
This is not your problem unless you have changed the r/w for special accounts elsewhere.
I have the same on my HD. But it's the individual files that are important.
Nothing there indicates that it should be locking her account out.
How do you create a new admin account from the Leopard DVD? It wouldn't allow me to do much of anything except Disk Utility.
I have not done it so I don't know, but there is a way to create a new administrator account using the DVD. Search these forums because I know others have done it.
Would it be possible to attempt to change things back by booting into single user mode? If so, what do I need to do?
I am not sure you can even boot into the Single User mode, or do you mean the Super User mode?
You have taken write privs away from everyone so I believe only a Super User can fix it. I am not even sure the Sudo will work in your case.
Thanks for your help!
If you find out how to access your drive from the Leopard DVD, you need to invoke SU privileges and undo whatever it was you did.
Were you using Time Machine? That would make fixing it a piece of cake. Just revert to the last backup before you made these changes.

The underlying task reported failure on exit--what do I do?

Long story short: Quicksilver G4 OS X 10.4.11 got stuck with the spinning color wheel using Eudora email, couldn't Force Quit, eventually it froze completely. I pulled the plug, restarted and ended with a blank blue screen (after the Apple logo and startup "wheel"). Reset the PMU, no difference. So I booted from the Tiger install DVD and got to Disk Utility. First, it didn't recognize any hard drive. So, I switched batteries, restarted, and the hard drive showed up. So I ran DU again, and came up with "the underlying task reported failure on exit" about 2/3 of the way through repairing the HD. Now I'm stuck.
My questions:
What difference did the battery make and why?
What do I do to repair the HD now?
Thanks!

Odell:
As roam indicated Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory error that cannot be repaired by Disk Utility. The article linked suggests the use of a third party utility. Disk Warrior, recommended by roam, is one of the best utilities for this kind of work. Tech Tool Pro is the other utility of choice for this kind of work.
If you do not have a current backup of your data, you should look to that immediately. If you have your data backed up, another approach would be to reinstall the OS choosing the Archive and Install option.
Although this error is essentially a directory error, it can, and sometimes does, be rooted in a hardware issue, e.g. a failing/failed Hard Disk Drive. I suggest that you boot from the Apple Hardware Test disk and run all tests in a loop by holding down Command + L during the tests. It sometimes takes many many repetitions and several hours to detect intermittent issues, so leave it run and check on it occasionally.

The underlying task reported failure on exit - HHD problem

Hi !
I am contacting you because I have a little problem with my ibook g4.
As a matter of a fact, this morning - everything was normal yesterday, maybe a little bit too hot, but well, quite normal - I have noticed something a little bit weird (I am using Tiger, X.4.11), the clock won't appear anymore, as the w-lan logo,. on the upper bar of the desktop.
Well, I have launched Onyx, which says that it seems to be a problem.
Well, I run the Disk Utility, clicking on "verify Disk", and some moments later, a new window appears :
"Disk Utility stopped verifying “iBook” because the following error was encountered:
The underlying task reported failure on exit"
And on the summary, it was written :
"Verifying volume “iBook”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link_
The volume iBook needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair"
So, I would like to repair by clicking on the repair button, but which wasn't avaible.
So I have tried a boot from the Tiger cd, and launched the disk Utility from there : it lauch, and it stopped at the same step, but the "repair" button was avaible. I clicked on, but the same message, ""Disk Utility stopped verifying “iBook” because the following error was encountered:
The underlying task reported failure on exit" Appears also, so it seems impossible for the disc to repair it self.
So, I have tried something else, a boot in "safe mode", holding the Shift button during the booting. And well... the results are a little bit weird too : first one, the computer do not even mark it, the second time, the time I think it would have been proceed, the white screen with the searching apple appears, search, search for a while, and then, the computer just.... turn off.
So I am really disappointed, and in a hurry, beeing on my university exam time... I haven't really the time to fix it, but I haven't the choice, and I'm a little bit afraid that my computer has something really important...
Thanks a lot for helping,
Best regards,
T.

Disk Utility reports "Underlying task reported failure" when repairing a volume is a directory error which DU is not able to repair. The article linked above suggests the use of third party utility. If you have access to one of the following it might help:
Tech Tool Pro
DriveGenius
Disk Warrior
This error is often, though not always, caused by a failing of failed HDD. Do you have the original HDD that came with your computer? If so you might want to consider replacing it, because even if the directory is repaired the drive may not be able to hold the format and the corruption may recur.
Here are some other suggestions you might try:
• Download and install Applejack
• Restart computer holding down Command + S
• When Command line comes up type in
applejack AUTO
Let is run all five functions.
Another option would be to back up your Home Folder, then completely erase and zero out your HDD, reinstall the OS and restore your data from the backup.
Also, take a look at Kappy on Error -9972 and the suggestions there.
Good luck.

Error: The underlying task reported failure on exit

Hello,
I get this error when trying to verify the mac's HD. Is this error benign? Should I boot from DVD? Does the disc need to be the one that came with my Mac or can it be a friends? Is this serious?
Sorry for the barage of questions but it's a little worrying.

DCE--
When you got the error recurrence, what copy of Disk Utility were you running--the one on your computer or the one on your install disk?
When I was using my installed copy of Disk Utility, I think I had one of those "spurious errors," although heaven knows my G5 is still not behaving some weeks later. I got the "underlying task reported failure on exit" thing when trying to verify my hard drive. If memory serves, though, Disk Utility's onscreen instructions tell you not to run "verify disk" or "repair disk" functions off the drive you are trying to check. (Unfortunately I'm not at my home computer right now). At any rate, I later spoke with somebody in Apple support and he told me that Disk Utility verification reports are "meaningless" when the application is run from the drive being verified; you have to run it from the install DVD. When I finally got THAT to work (first I had to learn that a Mighty Mouse does not necessarily behave according to its settings when talking to the disk drive), Disk Utility said no repairs were necessary.
