Power supplier lost

Hey

I lost my power supplier for my External Hard Drive.

the product Model is WD10000H1U-00( My Book Essential Edition 2.0 )

I tried to look for a new one, Universal or something but everyone is telling me that I should give them some specification about the Supplier. Like

Ampere(A) how many

input V( that should be about 100-240 VAC)

Input Frequency

and all other things that could help my to buy a new one.

There should be specification on the back of the power supplier, not sure thou

Thanks and excuse my bad English.

This link should show you your power adapter with the info.

However, if you want, you can contact WD to see if you can purchase a power adapter from them.
