Is this of any help?
http://linuxexpresso.wordpress.com/2010/03/31/repair-a-broken-ext4-superblock-in-ubuntu/
Summary:
Says to do:
mke2fs -n /dev/sda1
to discover where the superblock backups are stored
then to replace the bad superblock
e2fsck -b block_number /dev/sda1
'block_number' being the first backup block number in the mke2fs -n
output.
Excuse me if this is all off the mark.
