Re: HELP ! !!

I desperately need help ! ! !
I am using WD My Book ext. HD & My cloud ext hd. I’ve gone through about 3 or 4 in the last 7 years.

Recently due to unforeseen circumstances, the drives were separated from the power supplies. After perusing alot of forums and asking questions the wrong power supply may make the drive NOT work properly, including intermittent non readable.

Question: Is there a way to be able to identify the correct power supply to the correct drive?

Thank you in advance ! ! !

My Book: 12V 1.5A 18 Watts
My Cloud: the same

see the full list for all types of My Books and My Cloud power requirements.

Thank you !! !
now to trial and error everything
Maybe this Time I’ll label the power supplies?

Rated voltages are as stated-- Positive pin is center of barrel.

(Some universal supplies let you switch that up, so just covering that base as well.)
