I've just tried this dd'ing /dev/zero over the front of the disk
first to no avail (the probed geometry is the geometry that fdisk
used anyway).  I also tried your much loved ficticious geometry of
255H 64S and that didn't work.  It's a RPITA.  In the end I dangerously
dedicated the disk and that works.
