This is also true for the Dragon Data version of OS9, the Dragon 
supplied ddisk, was not capable of using double sided disks, as I guess 
it was written to use the Dragon Data supplied drives, whcih like the 
CoCo ones where SS40. It could however be tweeked with apropreate 
descriptors (or dmode), to use 80 track disks.

Cheers.
