The Commodore 1541 floppy diskette drive is notorious for breaking down. The Commodore SX-64 floppy drive is no different. As I continue my Commodore SX-64 restoration, I find that the 1541 floppy drive doesn't read diskettes any more and makes a chattering sound when attempting to read a disk. In this video, I walk through how to diagnose the SX-64 floppy drive as well as possible remedies before finally replacing the 1541 mechanism with a standalone drive.
