[qanda]This thread is about the Western digital My Book Essential Edition 320GB. Click here to see full specs[/qanda]I have Model WDH1U3200N. I have lost the power supply adapter, and need to know where I can get another, or a technical description of one that will work with the unit. The connection on the back is a male connection for a female plug, and it says DC IN. Can anyone help me with this?
