	If a hard disk has been formatted with DOS version "X",
	what determines whether or not you will be able to read
	it when you boot DOS version "Y" from floppy.

	We just loaded 3.2 on our system (PC6300, 10 Meg).  If
	you boot version 2.11 or 3.1 from floppy, and try to
	access the C: drive, you get an "Invalid drive specification".
	I think that it may have to do with cluster size, but the strange
	thing is that another machine (also running 3.2) CAN be
	booted with a different version and read the hard drive just
	fine.  Any insight would be appreciated.
