I don't think the 400K drives will work on the SmartPort.  Then again, I
don't think they'll work on the Superdrive card either.  IIRC, only
third-party controllers supported them.

The technical issue with the 400K drive is that they need a PWM motor
speed signal which the Mac hardware generated.  Unidisks, 800K drives,
Apple 3.5 drives, and Superdrives generate their motor speed control
internally.
