Isn't there some way to disable the positioner drive (either by pulling a
plug, pulling a PCB, or an internal switch)? The RK05 has a switch on the
servo power amplifier for this, for example.

If you can disable the positioner (and if the drive logic doesn't care!),
you can then run the blower for half an hour or so without the heads
trying to load.
