You previously said the partition indicates a problem and you are unable 
to even run fsck on it.
If the superblock is damaged you can use fsck and tell it to use one of 
the backup superblocks from the partition to  do its checks.  Man fsck 
for more information on how to do that.  Doing it this way also fixes 
the corrupt superblock.
