I'm working through a problem with the second drive in my DuoDisk unit. Specifically, it spins up, but the head doesn't read the disk.
This leads me to suspect two possible culprits: the read head or the stepper motor.
Is there any troubleshooting tips? Any way I can rule out the stepper motor at least?
I take it back. I didn't realize it, but the characteristic chatter when a disk drive starts is the stepper motor. So presumably it's fine. That leaves the read head...
