Try fsck -b 32 <filesystem>.
If that fails, try fsck -b <another number> <filesystem>. To get
the other block numbers for alternate superblocks, use newfs -N,
which will go through all of the motions of creating a filesystem,
e.g. print the superblock numbers, without actually creating a
filesystem. If this fails, you're pretty much hosed.
