Since you have to write a little device driver, you also have to take care
of the media change state. If you return 2 all the time at Mediach() calls,
TOS should not keep old information it it's caches.

BTW: Do you address the drive on file or on block level? If you write some-
thing that intercepts the trap #1 vector, you don't have to do anything
like this, since *you*'ll get all calls first...
