If I'm reading this right, you mean you got one of those combination
drives with a 3-1/2" and 5-1/4" in a single half-height drive. Right?

That 5-1/4" drive is a 1.2 Meg drive and those will not work properly on a CoCo.
The drives are designed to spin at different speeds (among other things.)
Something like 360RPM vs. 300, istr.

You probably need to use one of those "really old" drives as CoCo drive 0
and a new 3-1/2" drive as drive 1. They sell kits (probably $5.00-10.00)
to mount a 3-1/2" drive in a 5-1/4" bay. This will include brackets and cable
adapters for power and the data cable.

Then you can use your PC to write CoCo floppies on 3-1/2" disks.

Good luck,
Bob
