    Iread the Apple Support page about it and got something that was very confusing:

    [quote]How To Run fsck From The Startup Disk





    1. Using the System Disks application, select the Mac OS X Server partition of the hard disk as the boot device.



    2. Check the "Show Diagnostic Info During Boot" option (this adds the -v flag to your Open Firmware boot command), and in the 'Other Options' field, add 's', for single-user mode. (Do not put quotes around the letter s in the 'Other Options' field.)

    You may also click the 'Advanced Options' button and manually edit the boot command to read:

    0 bootr -v -s

    If you add the -s, it should be unnecessary to hold down the 's' key as described in Step 3.



    3. Restart the system, holding down just the letter 's' to force single-user mode (if you didn't add it to the boot options).



    4. Start (or restart) the machine in single-user mode. At the # prompt, type:

    fsck -y

    The fsck utility will go through five 'phases' and then return information about the disk's utilization and fragmentation. If the utility reports any errors or other conditions that it fixes or salvages, you must run it again until no errors are reported. This is because additional disk problem may be uncovered as a result of the first-pass repairs. <hr></blockquote>



    What the hell is meant by the System Disks application?

    And,

    where do I find the place that I can select "Show Diagnostic Info During Boot" ?

    The excerpts above appear to be for SERVER Mac OS X.



    To use FSCK:



    Restart the computer, holding down the S key (some folks say Apple-S or option-S), Use whatever works for your machine.



    The computer will boot up and present what looks awfully like a DOS prompt. Instructions for used FSCK are usually shown right above the prompt (Apple is guessing that you want to do this).



    Type the command as shown on screen or in the above response. Wait until it is done.

    Run it again. until it finds no problems.



    When it reaches that point, type rb at the prompt or bye and the computer should restart normally.



    :-)
