I plugged an identical HDD to the controller and it works, so I think 
it is either 'sticktion' or bad electronics. My feeling is 
electronics, as something may have gone poop with the power-outage. 
Now, has anyone tried swapping either the platters/electronics from 
one disk to another? If so, what what should I do, and should I AVOID 
doing?

TIA,

Guillermo
