...One issue I can see is that since both "drives" use the same head, stupid

shall see.
On the Pro, the software sees a fairly traditional CSR set with disk address registers
(sector and track). So an assumption like the one you worry about would be in the
controller, not the OS. If it works at all then that would say the controller doesn't
make that assumption.
