| You can freely mix drive rotational speeds in either direction on ANY
machine.
Whatever happened "in the not too distant past", it had NOTHING to do
with drive rotational speeds. I'm not questioning your statement that
the BIOS wouldn't recognize the drive, but rotational speed was not, and
had nothing to do with, the reason for that. [the most likely reason was
simply the capacity (size) of the drive]
Similarly, you can mix data transfer rates (ATA/66, ATA/100, ATA/133,
etc.) without restriction, although the computer may end up operating
the drive below it's maximum speed for any of several reasons. But all
drives are fully backwards compatible all the way to very slow PIO
modes, thus there are no issues in mixing different speeds.
