Floppy Disk Drive Stepper Motor Alignment
Support Noel's Retro Lab on Patreon: https://www.patreon.com/NoelsRetroLab
Join me in this episode as we fix a 3" floppy disk drive and then realign the stepper motor. This is a fairly common fault in these kind of drives (present in Amstrad CPC, PCW, and Spectrum +3 computers among others) that results in the dreaded "Drive A: read fail" error, so you're likely to encounter it sooner or later. We'll look at what exactly it means to align the stepper motor, we'll see how to do it with an oscilloscope, and then we'll wrap it up by doing it by hand.
Chapters:
00:00 Intro
00:28 Problem explanation
01:05 Drive examination
05:14 Push test
07:18 Cleaning the guide rail
09:47 Disassembling the stepper motor
10:40 Disk structure
12:56 Preparing for alignment
14:46 Aligning with oscilloscope
20:30 Aligning by hand
23:31 Conclusion
