YEs. While the model number is a good guide, it's not always reliable.
Particularly not when some mad hacker (like me) has been swapping bits
between drives to configure the unit he needs. I might well move an 80
cylinder head and stepper assembly onto a chasssis that once held a 40
cylinder unit, and then not change the model number label.

The onyl way to be sure is to test the drive!
