Just for info - I have a WD EX HDD (two years old) for which the power supply failed, 3 months or so ago. I tried to get a replacement power supply but as this one had a 5 pin (like a din) socket I could not source one. Two weeks ago I read an article regarding lots of issues with the power supplies given out with this unit. To cut a long story short I followed the advice given, this was to get onto the WD website and using their forms email them with the problem. End result is that they sent a new one totally free of charge. I received the unit today..well done WD..
