 Was your filesystem on /dev/da0s1 "UFS version 1?"
 
 See "man fsck_ffs":
 
      -b      Use the block specified immediately after the flag as the super
              block for the file system.  An alternate super block is usually
              located at block 32 for UFS1, and block 160 for UFS2.
 
 If you had UFS2, which is the default since 5.1-RELEASE for almost 4 years,
 you should have used 160, instead.
