Hello.

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
in.

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.

Enjoy.
