Unless that rescue disk has old filesystem tools on it, then it has the
potential to do more damage than good. If you can still boot from the fs
going in/or down to single user mode and remounting the fs read-only
(mount -o remount,ro <fs>) and running a fsck shouldn't cause anymore
damage. It's wise to check you kernel messages and make sure it isn't
puking out DMA errors etc before you go running fsck to make sure that
broken hardware isn't going to corrupt the data further.
