I have a Fujitsu M2551A, 360K floppy drive. I want to use it for writing images to disk using my Greaseweazel device. In fact, I did successfully write one disk with it, but now I can no longer get the spindle motor to turn. I can still make the head seek just fine.
Other drives still work fine on the Greaseweazel.
The Fujitsu still works fine when hooked up to a regular floppy controller.
I thought maybe I did something to damage/weaken the Greaseweazel's Motor-On output, but just using a multimeter, I can see that pin 16 drops from 5V to zero when the motor is supposed to spin. Perhaps there is there a different signal I should be looking at?
Could this be a symptom of capacitor aging?
