2nd catch, behind the power on time:
PWDIS drives: if you're not using them somewhere with sata 3.2/3.3, you need to use an adapter for the power plug, or some tape, to block pins 1-3 (3.3v) as supplying it to these causes them to reset.
Might be worth doing the taping anyway, if you're using an enclosure or cage (where you can't use the adapters)
