that is slightly strange, could the fact that the drives are variable speed have something to do with it?
Note that all Mac floppy drives are variable speed. The difference between the 400K and all the later ones is the speed of the 400K is directly regulated based on a PWM signal from the motherboard, while all the later ones automatically change speed based on what track they're on. (IE, they ignore/don't need the PWM signal.)
