Erm -b doesn't mean that (I don't think it ever has!).
Starting the fs anywhere other than 8k is a PITA - you need to be VERY
careful to ensure that any old superblock (eg from an FFSv1 fs) is
overwritten. Otherwise mount and/or fsck WILL treat the disk as FFSv1
with the expected consequences for your data.
