    Yes, boot from your original OS CD/DVD, and run Disk Utility from that.

    If THAT persists in displaying an error, back up your data pronto.
    Consider getting a big-gun disk repair program like DiskWarror or TechTool Pro, or taking the machine for service.

    I got the same error a few days ago. Had to run an archive install.

    I would say boot into single user mode and run fsck.

    reboot - hold cmd-S, when the black and white unix prompt appears type (assuming 10.4) "/sbin/fsck -fy" without the quotes, and hit enter. That should fix the problem. Then just type "reboot" and hit enter again to restart.

    I'm fairly certain that Disk Utility is just a frontend for fsck, but with the above method you don't need to go digging for a CD/DVD to boot from.


    As an aside, Diskwarrior is totally worth getting ... it'll fix all kinds of drive funnyness that DiskUtility won't touch.
