	Ack!  It should check the checksum.  If you do this, you won't be
able to read the rigiddiskblock from any RDB editor I know of, nor will
you be able to drop it onto another controller without losing your
partitioning information.

	Doesn't GVP ship _some_ sort of RDB editor with their HD controller?
Both Microbotics and Commodore do.
