Have you tried to run with backup superblocks?
Don't forget to use -n option, that will mount file system read only.
If yes than you can try to define different cluster sizes, but please see
#man e2fsck
first; there is a lot of options that you may try.
Don't forget to check mke2fs(8), tune2fs(8), dumpe2fs(8), debugfs(8).
Each of programs can give you more ideas what to do.
