Disk Utility says disk is corrupt after running fsck -fy Disk utility reports that the disk needs to be repaired.

I can't find the original boot disk, so I booted to single user mode and ran:

fsck -fy


This reported that it fixed a problem, and that the disk had been modified.  Re-running it a 2nd time said that it was OK.

So I restarted, and tried running the Disk Utility app again - and it still reports that the disk needs to be repaired.

Repeat, with the same results - fsck says it has repaired the volume, but the Disk Utility says there are problems.

I also tried running diskutil repairVolume but it would not run because I was in single user mode.

Is there anything else I can try to repair the volume?  Is there a way to create a bootable DVD/USB from a running system so I can try running the Disk Utility app?
Honestly, you don't mess around with these messages. I think that the first thing to do is to make sure you have a complete backup of your hard drive. Get a second drive with enough capacity. Use Carbon Copy Cloner or Time Machine, or Super Duper to copy the drive.

Once you have a backup, you could easily reformat the drive, (this will avoid bad sectors), and then copy back from the backup.

My 2¢ Hope this helps..
