instructions to suggest the power requirements. Simpletech has not answered

Can you open the case? If so, then identify the power pins on your
drive and check for continuity with your power socket using a
multimeter. That should give you the required voltage(s) and the
correct polarity.

Another guide would the polarity and rating of any electrolytic
capacitors.

A photo might help also.

Good idea. There are enough competent people here to
interpret that. Post a photograph of the insiodes and
a close-up of the power inlet.

Look at the pictures of the PS at www.newegg.com

Most likely a 12v DC 2.0 amp

I may just have to check the configurations of the candidate supplies and
hope that their polarities are all the same then check which power plugs fit
the drive (when it's off.) After that, flip a coin maybe. Or buy the exact
same drive again at Fry's Electronics, check the power adapter used then
return it.

First you can check whether polarity on all your PSUs is the same.
On the 12V only supplies si Have, all have ground on the outside
and +12V in the center.

You can also open the drive and look which pin is ground. Typically
ground is wired in black. You could also use a multimeter and
measure resistances from obvious ground points on the inside.
Often the drive case is ground. With a traditional 4-pin
molex connector, the wires in the middle are ground.

Arno

Why in the hell would you suggest that he/she open the drive and find the
polarity when it shows right on the back of the drive that the TIP is positive
and Sleeve is ground???

http://www.newegg.com/Product/Produc...82E16822100032

Right.

I wasn't sure of the power supplied on a USB port, so I looked it up. The
standard is also 5V, at no great level of current. I agree that a 5 to 12
volt converter in an external housing would be improbable.

The link from another poster (Gman) for a newer model (with both USB and
Firewire interfaces) shows what may be a single-pin power connector (not
counting ground).

I have several external drive enclosures with varying levels of cheapness.
(No rampant stallions in the lot.) All use multipin connectors.

Sorry to be unhelpful.

Not really! The drive you link to is their portable one which is
considerably smaller than mine - mine is a 3.5" desktop drive while their
portables are 2.5" ones that require less power. I'm almost certain mine
takes 12 volts.

All current 3.5" drives take 12V and 5V. It is relatively easy to
use only a 12V supply and generate 5V from the 12V inside the case.
While possible, generating 12V from 5V is far more expensive and
not done for this application.

2.5" drives typically only take 5V.

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, the OP stated "But this drive has nothing either on it or in the
instructions to suggest the power requirements." I take that to
include polarity, since it is the only thing non-obvious.

Apart from polarity, this will be a 12V 1.5...2A psu.
