The error message suggests a bad sector in the superblock, fortunately
fsck.ext[23] can use the -b option to specify the use of an alternative
superblock.  Try "fsck.ext3 -b 8193 /dev/hd??" this might work.  If the
1st spare superblock is not found at this location, fsck will not
continue so it should not make the situation worse.

Good Luck
