I have a WD 500G ext hard dish, but the power unit has got mixed up with a number of others. Can anybody tell me how I can find out if the centre pin is 12v+ or 12v- . I dont want to plug in power unit with the wrong polarity. Can someone tell me what 12v with broken lines under a continious line. 12 v ______ THanks
