I disassembled that broken roctec external floppy drive to see if I could fix it. It turns out that it's not a direct drive motor. The hub is driven by a belt. The belt had stretched way out so that the motor was just spinning. That's where the buzz was coming from.
So I managed to make a new belt from a rubber band. I had to cut it length-wise so that it was 1/8" wide instead of 1/4" wide. It just happened to be exactly the right length. That worked like a charm. So if you have a roctec drive with a stretched out belt, this is a good fix.
Now the bad news, it still doesn't work. The OS detects the drive and detects a disk insertion, but doesn't recognize it as a valid format. I tried to format a disk, but it failed on the first cylinder. It wouldn't read disks that would read in another drive. I even tried the other 2000, so it's definitely the drive. Luckily, the lady i bought it from is sending me another one for just the cost of shipping.
Oh, and the switch on the back, 0, I, II, it's not a drive select. That seems to happen automatically. The switch performs other functions. II seems to write-protect the drive. I lets it write. I can't figure out what 0 does.

Most likely it disables the drive.
