Did you use the -b altsuperblock option to e2fsck? You may need to
run the mke2fs command with the -n and -b blocksize options to locate
the alternate superblocks, and maybe the -c option to run badblocks
as well.

man e2fsck

Good luck!

Thanks Jim. I am probably being thick here but how do I find out what
blocksize to tell mke2fs?
