That isn't supposed to work.  You don't write a disklabel to a hard drive on a
PC, you write a MBR using 'fdisk'.  disklabel ad1 auto should fail.  Right now
it does DD mode.  If you don't want it to fail, it should write a disklabel (not
a MBR).  (If this is a non-boot disk in a FreeBSD only system this would be ok.)
