I can't find any technical info on this drive in the online space... you have three options:
(1) post everywhere and wait for someone who has drive to give you an information
(2) look at the power connector, how many wires are in there, open the drive and logically identify what wiring is and what is required voltage
(3) go where you have taken the drive and ask for power adapter... even if it's damaged
Can you post pictures of the drive's power connector and internal PCB?
