I haven't had any belt issues so far with my numerous Commodore 1541 disk drives, though I suppose it's possible.

I'm not saying that the belt went bad. I'm saying that the spindle on the other end of the belt might be stuck. The motor of the drive might be fine, but the spindle on the other end might not have enough lubrication to spin like it should, thus causing the belt to get stuck and smoke.
