OK Cool, I would be interested to know what the technique for that is
(raw copy).  There is a dw command to create the images on the fly.
There are no tracks in DW, just linear sectors, but since sectors per
track is usually fixed I guess it doesn't matter?  It seems like while
you could create the image from the disk, and create a disk back from
the image, you still would not be able to actually mount the image via
hdbdos, since it is 35 track only.  could probably use the toolshed to
turn those > 35 track disks into regular 35s though, either splitting
across 2 or looking for disks that fit on 35 in the first place.
