I have this early 2010 model of WD My Book. I don't exactly remember what power adapter it used back in the day. Can anyone suggest the particular power adapter with accurate voltage requirement for this WD My Book. Images are included.
Connector size = 5.5mm x 2.1mm / 2.5mm (The inner spring inside the connector closes to 2.1mm and opens to 2.5mm)
Centre-pin Positive
12V DC and 1.3A
1.3A and above will be fine for your drive
