There should be multiple superblocks.
UFS filesystems always have another superblock at 32. Then one per
cylinder group. You need to know the disk geometry to calculate the block
numbers of the remaining superblocks.
Its always a good idea to save the output of newfs, which lists the
superblock block numbers, and print it out, or put it on another machine
in case you need it...
