    I ran the disk utility and got the following result. What does it mean?

    Checking Extents Overflow file.
    Checking Catalog file.
    Incorrect number of thread records
    Checking multi-linked files.
    Checking Catalog hierarchy.
    Checking Extended Attributes file.
    Checking volume bitmap.
    Checking volume information.

    Run the repair disk.

    Do you have 2 partitions on it ?

    Unfortunately, the "Repair disk" button is not clickable. I do not have the option to activate it.

    I do have 2 partitions. One for OS X and one for bootcamp.

    Boot off your install disk and run disk utilities.Then repair the disk.I've seen this in a few 2 partition map schemes on Macs.No big deal.

    I tried to run the disk utility off the install CD #, but it still does not work. Refer to the attached pic to see the result of the "verify disk" action.

    I am asked to repair the disk, but I cannot even click on the repair button, as it is not highlighted.

    What can I do now?

    Acquire DiskWarrior, that fixes it.

    I get the same on my MacBook Pro, I also had the same on my PowerBook G4 1.67GHz.

    Interestingly, I never encountered this problem on versions of OS X prior to OS X 10.4, so I'm thinking it's something directly related to this version of OS X.

    I just ignore it until I do a wipe and reinstall once a year. Mine's exactly the same and I've yet to encounter a problem.

    DiskWarrior does fix it. But it does comeback.

    Did you:

    1. Put the CD in
    2. Turn your computer off
    3. Hold down the C key and turn the computer on (hold the key until the Apple comes up)
    4. Select your language
    5. From the Utilities menu select Disk Utility
    6. Select your dive (not the partition) from DU
    7. Click Repair

    Ah, you got me. I did not know I had to restart the Mac to run Disk Utility from the Install disc.

    My Mac is now okay. I could repair the hard drive.

    Thanks a million.

    If you are ever in the same situation, but don't have an install disk handy, you can accomplish the disk repair by rebooting the computer into Single User Mode.

    Reboot the computer, and when you hear the chime hold down command-S
    Wait until you see white text scrolling across the screen.
    When it has finished, you will be at a shell prompt (some text with a # character at the end).
    Type the following commands:
    /sbin/mount -uw /
    /sbin/fsck -y

    'fsck' is an abbreviation for Filesystem Check. When its done running, you can reboot your computer with the command:
    shutdown -r now

    And it will restart normally.

    Yes that will work but since the file system is journaled you will have to run /sbin/fsck -yf and only run the first command if you want it on only check and not repair (it cannot repair the drive if it is mounted).
