My Tiki 100 (Norwegian machine with CP/M 2.2 compatible os) has two floppy drives: Epson SD-521 (5.25 inch, 40 track, 360k). But only one of them works. So far I've done a visual inspection, as well as a visual comparison of the drives in operation. Both drives spin when accessed (with a floppy in the drive), but on the faulty drive the head doesn't move. Nothing looks wrong with the faulty drive, and when it is without power, I can easily move the head assembly back and forth. With power on, I feel the resistance from the stepper motor.
Before I dig further into this, does anyone have service manuals or repair tips for these drives? I didn't find anything when searching, so it is probably a long short, but still.
