WD external hard drive WCAV

Need your help guys, I recently had my drive in pawn and got it back with the cords missing. I need to find out what type of ac wall adapter would fit. They gave me one but it fits but doesnt turn on the unit…Please let me know if anyone of yall knows the size…Thanks a million!!

WCAV is not a model number … well, not a complete one anyways. (partial model numbers don’t help in identifying a product)

Anyways, without knowing what external hard drive you have, look for it in the link below and what power supply it uses.
