Step 1: Parts List

You will need:

1. A 12v Switching Power supply capable of 1A.
2. A power plug that fits said power supply
3. A piece of wire (about 3.5" long)
4. An Xbox data transfer cable
5. A full size SATA hard drive
6. A hot glue gun with a stick of glue ready
7. tin snips or pair of heavy duty scissors
8. A little time
9. (optional) patience

Step 2:

A note on the power supply and plug.

I have stressed the word switching as it is very important. A normal "wall wart" is an unregulated voltage source. It will put out the correct voltage ONLY when it has about 50% to 60% of the rated amperage being pulled from it. Output voltage will also fluctuate with the line voltage. For a hard drive this spells disaster. A hard drive needs a REGULATED and CONSTANT voltage.

It's always a good idea to make sure the plug fits the power supply! XO

Step 3:

The two halves of the data transfer cable are glued together. I used a flat head screwdriver to split them apart. Be gentle.

Step 4:

You will have to remove the circuit board and the shielding case from the rest of the case for this step. Remove enough shielding material to accommodate the new power plug. Only take as much as you need to accommodate the plug but leave enough to solder to the plug negative pin.
