/dev/ad3: 38166.7MB (78165360 sectors) block size 16384, fragment size 2048
using 208 cylinder groups of 183.77MB, 11761 blks, 23552 inodes.
super-block backups (for fsck -b #) at:
160, 376512, 752864, 1129216, 1505568, 1881920, 2258272, 2634624,
3010976, 3387328, 3763680, 4140032, 4516384, 4892736,
....
After which you could do a fsck_ufs -b 752864 device_node (first time
with -n also) and see if one of the alternate superblocks fits.
