Hi Bob

I can't absolutely guarantee that every single PG Music case ever sold would be the same, but I just verfied that this works with one of the nice black PG Music pocket drives that came with BB 2010.5.

It works fine with a 5 volt DC wall wart power supply. Tip positive.

The little PS I tested claims 1.6 A current capacity. I suspect even a smaller one might work with the newer drives which do not usually require as much current.

I have bought a lot of different brands of 2.5" hard drive enclosures over the years, and every one which had a DC jack, was spec'd for 5 volts DC tip positive. So there may be odd ones out there with some other spec, but it seems pretty standard.

Some of the external enclosures I've bought came with such transformers, so there are several of em laying around in my house. They all look about the same, and there may be one factory in asia somewhere that makes em for everybody. Or maybe it is a very standard item that many transformer factories crank out.

The transformer I just tested with the PG Music drive is one of the transformers that came along with some random hard drive case from years ago.

Unless you are in a real hurry, maybe it would be a "little better" to order a small transformer from one of the computer webstores because the little transformers have the perfect size plug and do such a good job, and are no bigger than they have to be for the task.

You could get something from Radio Shack that would work fine, but unless they now sell one "special" for the little hard drives, a generic would be, well, more generic!
