Todd Wallace helped me verify this yesterday.  I never knew this, but
you can in fact copy files and entire disks between real floppies and
DriveWire disks by using the DRIVE OFF command.  Once entered, drives
0-3 will be your real floppies and drives 4-255 are DW disks.

HDBDOS for DW maps coco drive #s to DW drive #s strangely.  It maps
all requests to DW device 0 and offsets the sector requested by (coco
drive # x 630 sectors).  This means that all requests will come in as
if they were for drive 0, even though you want to use drive 4+.

DW4 has a special mode that maps requests back to the proper drive #
based on the sector, basically the reverse.  This allows you to easily
map files into the proper position for requests from HDBDOS.  To
enable this mode, specify:


in any <Instance> section of your config file.  Please note that this
mode will cause awfully strange results in NitrOS9.  Of course, in OS9
you can access real floppies and DW disks together very easily in the
standard mode.  Todd is working on a tool for duplicating entire DW
disk images to real floppies.

Hope that helps some folks, I've been asked about copying between real
disks and DW disks several times and never knew a good answer for DECB
