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...
