Which power adapter - Specs?

Hello -
I have a collection of power adapters & don’t remember which one goes with my WD MyBook HD.
I can’t find specs…
I don’t remember what the capacity is (likely 3 or 4 TB)
It’s less than a year old.
The P/N is: WDBFJK00040HBK-0A

The unit indicates that it takes 12V.
One potential adapter is 12V - 1.5 Amp., the other is 12V - 2.5 Amp.
I don’t know if putting an extra amp into it would harm it, but it seems like better safe than sorry.

Thank you. Any help would be greatly appreciated.
