I have no idea where the original AC adapter went for my WD Elements Desktop hard drive (model WDBWLG0030HBK-NESN) so i got a third party one from amazon with the same specs. Now the hard drive won't turn on at all, and I have no clue why. The new AC adapter is 12V, 2A, and center positive polarity. I tried multiple outlets, and wiggled the port even though it fits nice and snug. Any idea what's going on or is there anything else I should try?
