After fdisk creating partitions try,

dd if=/dev/zero of=/dev/da0s1 count=16

Then disklabel -r -w and disklabel -B

Tru64-UNIX has a disklabel -z option which zeros out the disk label.  
Compaq and Digital before that recommended disklabel -z prior to laying 
down a new label.  Should we consider a -z option for our disklabel?
