| molex connector, the wires in the middle are ground.

The drive has the usual power pin configuration indicated as center pin
positive as expected. Opening the drive will void the warranty according to
a sticker I'd have to remove. Interestingly, the drive is assembled in the
US.

Well, so there is an indication of power polarity. Now look for
a PSU with the same polarity (marked in the type-shield) and
12V at 1.5...2A. That will do it.

Thanks to everyone for useful advice. Based on the pics at Newegg (linked by
GMAN) and the suggestion by Arno that the adapter would have 1.5 - 2A output
at 12V, I was able to narrow the adapter down to one which I checked for
proper polarity with a multimeter. That was it and I'm back in business with
my backup drive. I'll be printing out a label for the adapter shortly.
Thanks again for the help.

Very good and you are welcome.

Glad you figured it out!!!

Now i need to track down a replacement 12V/5V supply to replace a bad one that
wont output enough amperage to run my external case. It has a typical 4 pin
mini DIN

My PSU (model JHS-Q05/12-S335, 6-pin mini DIN) is rated at 12V/2.0A +
5V/2.0A while my Seagate hard drive is rated at 12V/0.52A and
5V/0.72A.

However the PSU's plastic case feels very warm, even when the drive is
idling. Somehow I think the PSU's rating is very optimistic.

The PS i have that is underpowered is a GFP252-0512


I have found replacements online but i am not willing to spend the $30-$50 for
one. I have found a 12V/5V 2A supply at a local goodwill type store. I will
just likely take the cable from the bad supply and solder it onto the
replacement supply at its PC board.
