Sounds like your drive was physically damaged.
This recently happend to a mail server of ours,
and I had to reinstall the whole thing.
(After long fsck sessions, only a small part
of the file systems was accessible, and there
was nothing of value that could be salvaged)
Sorry for the Bad News (tm) :(
