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:
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?
