I have an old My Book Essential and I lost the power adapter. The external hard drive is 2 TB as I remember and I searched in the market for power adapters but it looks there are many standards.
Does anyone know what is the size and amp rating for this hard drive?
WD My Book Essential USB 3.0 P/N WDBACW0020HBK-01
I saw in some pages the rating is 1.5A and 12V DC but it does not show the size.
There are several sizes e.g. 5.5x2.5mm , 5.5x2.1mm and 4.0x1.7mm which one suits this hard drive?
