One might think that, and that plan works for an RK05, but an RL02 is
smarter. Unless the heads go on cylinder within a few seconds of the head
load signal, the drive logic just faults and spins down again. Not very
useful... What's needed is a way to stall or fake out the drive startup
state machine logic.
