Another method of obtaining a formatted disk for the Pro-3xx, is to
use an image copy program called Teledisk (shareware) for the PC.  Not only
does this program allow you to do a disk-to-disk copy, but it can also
store a disk into a file (on the PC).  This way, it is possible to keep an
image file of a blank P/OS formatted disk, and then crank out new copies
easily.
 
In my experience, low density disks (360k) on a high density (1.2m) AT class
drives seem to work out best.
