I have also had this problem, and a similar hardware configuration, BUT, it
has only happened once to me, Though I don't use Diga! or MWB.

I have figured out how to make RAD: and VD0: co-exist. It is actually fairly
simple: when you first load up the system from a cold boot, VD0: must be
loaded first, AND it must have stuff in it (MORE THAN one cylinder's worth
of data) BEFORE you mount RAD: for the first time (ie: create it). I copy
a small directory's worth of stuff (~6 files, >= 60k) into VD0:, mount RAD:,
copy stuff into RAD:, delete the stuff I copied into VD0:. This has worked
for me for several weeks (except for run-away programs that have clobbered
either/both of RAD and VD0). BTW, I only use a small (9 cylinder) RAD for
auto-booting my hard-drive (also a StarDrive). I recently saw a posting about
how to make 2 RAD: disks co-exist in memory at the same time, you might look
through recent posting history.
