Can't mount filesystem -- HELP!

[Greg Shonle]

[]
I'm having a problem mounting my second hard disk (under XENIX 3.0, on an
IBM AT).  Mount says 'mount: bad file system (65536)'.  This disk is a
non-standard disk (for an AT), but I've patched up XENIX to talk to it.
I haven't had any problems with the user partition (until now, that is),
although the root partition got mysteriously corrupted once (and I never
got around to putting anything on it since).  But now, I can't mount
either file system, and there are some files on there that I haven't backed
up.

So, if someone could please give me some ideas as how to mount the disk
again, I would really appreciate it.  I've tried fsck, including the -c
option, but to no avail (I haven't tried the -s option -- it looked too
dangerous).

(If it's of any help, I noticed this problem after a single user login,
of which I'm not sure that I shut the system down properly, since I couldn't
see what I was typing (my enhanced color display wasn't set up correctly)).

						Thanks in advance,
