This won't help.  The superblock wasn't affected; it was in good
enough condition that dumpe2fs and e2fsck didn't barf.  The problem is
that 0xFF was written on every other byte in the inode table, and
there isn't a redundant copy of the inode table.  (Every so often,
it's been considered, but doing so would close to double the metadata
overhead of ext2, and keeping a backup inode table up-to-date would
also significantly slow down the filesystem.)
