That only got added post 3.0

If you hexdump the start of the disk, the label is (probably) in sector
0 (or maybe sector 1, or maybe the first (or second) sector of a netbsd
mbr partition).  In any case writing zeros to the sector with 'dd'
will zap it (but you might have to use disklabel -W to make the label
unprotected [1]).


[1] run 'sleep 9999 </dev/rwdxd' in another window (or with &) to keep the
diak open.
