You can make a
stand-alone controller for the task - called a "drive
exercisor" or "exOrcisor"
I was given a drive exerciser (darn useful it is too...). It's a simple
microcontrtoller application and a bit of TTL to generate f and 2f write
waveforms (there's no read electornics in the excerciser, you use a
'scope for that).
Alternitvely, some floppy drive service manuals include the schematics
for the manufactuer's exerciser and a suprising number of those are just
TTL chips (nothing programmable/programmed), so something similar could
easily be made.
