"1 Volume could not be repaired because of an error."

Hello everybody. (For reference, I'm a total rookie in terms of tech stuff.)

All of a sudden today my imac started running unbelievably slowly. Had never had any problems before. (Still have about 100gigs of free hard drive space.) I tried restarting, no help. I tried turning off, waiting a few minutes, and rebooting. No help.

I found in the forums somebody suggested using the disk utility to repair disk permissions. I did that, but it didn't seem to fix anything.

I tried (based on another forum suggestion) rebooting with the installation disk, and running "Repair Disk." When I do that, it says this:
-----
Checking HFS Plus Volume
Checking Extents Overflow File
Checking Catalogue File
Invalid Sibling Link (in red)
Volume Check Failed (also in red)

Error: The underlying task reported failure on exit. (in red)

1 HFS Volume Checked
1 Volume could not be repaired because of an error. (in red)
-----

Anybody know what to do here? I'm completely at a loss.

Any help is quite sincerely appreciated.

iMac, Mac OS X (10.4.1)

That is a disk directory error. You will need a tool like Disk Warrior from Alsoft or Tech Tool Pro from Micromat to fix these types of errors.

Alternately, you can backup your hard drive's data to an external drive, reformat the internal drive, and restore from the backup.

Disk Warrior did it for me when I had the exactly the same problem.

when I booted from the diskwarrior cd, and tried to 'rebuild' the damaged partition, which in my case was time machine, i got a message saying that there wasn't enough free space. the error code was 2145. what do I do now?

I have not tried running DW on a Time Machine drive yet but from my experience if you get that error it means your drive is full or almost full. The way Disk Warrior rebuilds the volume is by creating a completely new volume directory then replacing the old one with the new one. Therefor you need at least enough free space for the volume directory to be duplicated which is actually quite small in size. The only other thing I can think of is that while the drive is designated for TM it won't let you write over the current directory. Try turning TM off then running DW. Though Repair Disk should be sufficient for checking your TM drive unless it comes back with an error it cannot fix.

hi george,I got that message when it(diskwarrior) was booted from the cd, so leopard wasn't running,which means no time machine processes or anything. And do you think the rebuild would work if I have enough free space on a 'different' volume/partition? because I cannot erase or modify the time machine volume. Leopard says its available to me in 'limited mode' so that I can backup my data.

What kind of drive are you using for TM? What size is it? and how many partitions do you have on the drive? Is the TM partition almost full?

the problem is that I got a volume check error on my external drive's time machine partition. I have a screenshot I took of the error prompt I get when I turn on my computer. It basically says that the time machine volume has encountered an error and it couldn't be repaired so its in read mode only. So time machine cannot backup anything on it. Repair with disk utility and drive genius fails and rebuild command in disk warrior gives me error 2145 after 'step' 5.

First turn Time Machine off in your system preferences then try running Disk Warrior on it while booted to your main system drive. However if you do not have the serial number you will have to boot up to the disk again. If you do not have any luck with that you could simply erase the partition and start your Time Machine backup again from scratch. You might also check over in the Time Machine forum and see if someone is familiar with this problem.

the problem is that in leopard, even though I'm not running any other applications, diskwarrior says speed reduced due to lack of memory. Mine is an old machine with only 1 gig of ram. Still, I'll let it run and report back. Thank you so much George for helping out.
Well as of this time, its on step 6 constructing optimized replacement directory.
