    I ran fsck on /dev/rdisk0s2 this after a power cut and received the following error:
    I recieved the same error in Single User mode, so I tried booting off the Snow Leopard Cd and running the same command, it said everything on the drive was fine, so after rebooting back into OS X for one last check I ended up with the error above again, any idea on how to solve this problem?

    Also, according to the Boot CD I have about 300mb more free space on the disk than I do according to the file system

    I don't see where you tried running disk utility to repair the problem. Did you?

    Disk utility reports no errors either from the install cd (where both fsck_hfs and disk util report no problem) or from the computer (where both Single User fsck_hfs and regular fsck_hfs reports a problem, but disk utility does not.

    After repairing permissions I get the following:


    ** /dev/rdisk0s2
    ** Root file system
    Executing fsck_hfs (version diskdev_cmds-491.6~3).
    ** Verifying volume when it is mounted with write access.
    ** Checking Journaled HFS Plus volume.
    ** Checking extents overflow file.
    ** Checking catalog file.
    Invalid index key
    (4, 15379)
    ** The volume HDD cannot be repaired when it is in use.
    ** The volume HDD could not be repaired.

    Whats REALLY odd however is this error doesn't appear if I use Disk Utility or Fsck on the rescue CD

    Hey, I used this as an excuse to only run from Lion banishing SL from my Mac, however after following this procedure:

    1. Using diskutil zerodisk disk0
    2. Booting from a USB image of Lion Installer
    3. Installing Lion
    4. Installing Updates
    5. Repairing Permissions

    I'm getting the same errors.
