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..
