I do not know, why this doesnt work...
Is it possible, that amrd0 (or a partition/slice of it) is mounted somewhere?
U could try the same dd command with sysctl kern.geom.debugflags set to 16:
sysctl kern.geom.debugflags=16
dd of=/dev/amrd0 if=/dev/zero bs=512 skip=286746623 count=1
sysctl kern.geom.debugflags=0
That should clear the unwanted meta data...
