Some time ago I managed to destroy my /home (ran mkswap on it....). e2fsck
also failed on it and suggested to do a -b 8193 which also failed. After
reading the manpage I found out that since a few years the position of the
backup superblocks depend on the blocksize. For filesystems with 1k
blocksizes, a backup superblock can be found at block 8193; for
filesystems with 2k blocksizes, at block 16384; and for 4k blocksizes, at
block 32768. Maybe using -b 32768 will help ??
