Ah, that was it. They made the "R" model narrower to make it easier to
fit them side by side in a rack.
I'm guessing that the 9.5" size might match the size of the genuine IBM
33FD, 43FD, or 53FD drives. Although I have some 53FD drives, I've
never taken them out of the equipment they're installed in, so I haven't
had occasion to measure their dimensions.
