Well it's certainly not good. :(

Try restarting with the OS Install CD and running the disk repair from there. Hopefully that'll fix it all up... if not... back up! And if it does... back up anyway! Never hurts to have a backup.
 
I've had this happen to me twice, and I hear the HD making high pitch whines followed by clicks so I'm taking my NEW PB in to get the HD replaced.


Gonna get some more RAM while I'm at it though :).

I'm just going to give Apple crap because there is definetely something up with my HD, and the screen is bent -- both on a brand new PB.

yep, an on phone to tech support now

She has told me to run disk repair from my install disk, along with verifying disk permissions from install disk - not using hardware test.

im currently doing that, if it does not solve the problem (which apparently apple has never heard of) her advise...erase and install. thats just great then aint it!
 
sorry to bring up old thread...

but i ran disk utility from the osx disk and same error pops up.. what should i do?

i have a macbook coreduo by the way

DiskWarrior will fix it just dandy. (Apple's Disk Utility never has for me, even when booted from the Install Disc).

I started experiencing this problem when Tiger was released (Never with any prior version of OS X), and on several different laptops (TiBook, AluBook & MacBook Pro) too.

Considering that your average Apple Tech coulnd't find an arsehole between two cheeks, I say pony up for DiskWarrior should booting from the install disc and the subsequent repair fail.

Even if you erase and reinstall, the problem will reoccur (or at least it always does for me).

That said, the problem can't be that serious, I've been running my MacBook Pro with the same error message for christ knows how long now, and I've not seen any detrimental effects. At all.
 
Just to clarify -- you will ALWAYS get the 'failed on exit' message if you
1) run Repair Disk while you are booted from an OS on that hard disk, or
2) boot from another disk or CD, but run the Disk Utility application physically located on the hard disk you are trying to repair.
 
(Sorry to pull this thread up from the underworld, but I found this thread via google and there seems to be no solution poasted, so I'm posting what worked for me)


The apple website states this solution:
You may notice some "Incorrect size for file tempnumber" alerts when you attempt to verify or repair a volume using Disk Utility or fsck_hfs with the "-l" option. You can safely ignore these alerts for any "tempnumber" files.

For example, you might see something like this:

Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Incorrect size for file temp420595
(It should be 0 instead of 84538)
Incorrect size for file temp468627
(It should be 0 instead of 16464)
Checking multi-linked files.
Checking Catalog hierarchy.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair

If this happens, use fsck in single user mode, or start up your computer from a different volume before verifying or repairing.

And Mac OS X Hints has a breakdown of the command:
Boot off the OS X CD (reboot, hold C while booting).
The installer will load up, go to Utilities in the menu and run Terminal.
Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.

I had the same issue and that solved it within minutes. (fsck can take a while to run but it is an excellent tool)
