>> I¹m looking for some advice/whatever on engaging the motor when needed.
Forst if you running motor only when needed you need a delay in software
for the motor to come up to speed (1 sec does it).

It's possible the connector is upside down. The other is the drive in
use has a jumper for motor always on.
Also DS0 (thats a zero right?) needs to be selected to read or write
to the the zeroth drive.
