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?
** 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.
** Checking multi-linked files.
** Checking catalog hierarchy.
** Checking extended attributes file.
Incorrect number of extended attributes
(It should be 175599 instead of 175599)
** Checking volume bitmap.
Volume bitmap needs minor repair for orphaned blocks
** Checking volume information.
** The volume HDD cannot be repaired when it is in use.
** The volume HDD could not be repaired.
Also, according to the Boot CD I have about 300mb more free space on the disk than I do according to the file system
