If your filesystem is corrupt, you can repair it
(when unmounted!) with e2fsck.

You also described your disk sometimes being
by the bios and sometimes not. Perhaps the drive is
flaky and that is the underlying cause of your 
filesystem problems? Consider getting a drive stress
test utility from your manufacturer's website?

Anyway, back to e2fsck!

If you have a problem with the first superblock,
try specifying a different superblock with e2fsck.

Check out man e2fsck, the -b option. Try a few 
blocksizes if you don't know what block size you

Good luck!
