I had a problem with bad superblock last night (using lvm though)
To find an alternate/backup superblock do mke2fs -n <device>
the -n instructs mke2fs to just do a dummy run and not actually change
the disk contents, so this will list where the other superblocks are.
then you can do e2fsck -b <number> <device>
Hope this helps
