The answer would be yes. Issuing a @CPn where the value for 'n' is extracted
from the system partition (offsets $e2 & $e3)pointing to the default
partition value is sufficient for a FD-2000 disk image to be properly logged

A native partition can be created on a DSDD 800K disk by the FD-2000. Maybe
it should be called the D1M format? :) Unfortunately, it doesn't seem that
1581COPY supports that kind of format. The system partition is still on
track 81. If you really want to boggle your mind and muck up your
cross-platform project endeavors, the FD-2000 can format an ordinary 1581
disk and add the system partition onto track 81! The 1581COPY program
probably would not detect this 81st partition on an ordinary 1581 disk.
