5.25" drive identification

I guess you missed the irony.

  Yes. It is rudimentary and almost totally useless. If you've handled
as many hundreds of drives as I have, you'd know that color, shape,
size, door-type, whatever, has no bearing.

I mean, you can guess from experience and be right more often than not,
but if a customer called me by phone and described a drive, I wouldn't
venture to say 40 or 80 track, high or regular density etc without
testing the drive myself. Barring a test, a model number would be the
only other way I'd swear to a drive's capacity.

Regards,

Jeff

Boy, I'm so glad that is settled. Now I know how to identify any 5.25"
mech just by the color of the faceplate and soldermask on the pcb.

Wow. Why didn't I ever think of that?

Until this moment, I've been using silly things like model numbers,
testing, and something no one has yet mentioned:

        The step rate marked on the stepper in degrees. Sometime this
can yield a clue.

Regards,

Jeff

The beige faceplate on 360K is yellower than on 1.2M

360K has jumpers for drive 0,1,2,3; 1.2M has jumpers for A,B

360K has a screen that is usually white on black; 1.2M has a screen that
is white on blue. (If it bluescreens, then the drive is a 1.2M)
