Hi, I have completley lost my /user disk.. Here is what I got from my log
files... Hope someone will help me... e2fsck resulted in mess in
/lost+found :~~~~~~((((( /dev/hdc2 was /user home round 4gb big :((((

It looks like from the errors that (a) the superblock was corrupted, and
(b) you're using some form of the e2compr patches.

It probably would have been better to use an alternative superblock
(e2fsck -b 8193), but depending on how badly your filesystem was
corrupted, it might not have made a difference, since some of the
evidence you provided at makes it appear that part of your inode table
may have gotten smashed as well.

You didn't say how this happened --- how your /user disk got this badly
trashed. That might help give further information about why this
happened, but it might not. The main lesson I would take away from all
of this is that any responsible sysadmin should always be doing
frequent, reliable backups of any data files that he/she really cares
about and can't easily reconstruct.
