Hello, I popped the case off of a Seagate external FreeAgent HD. Inside there is a thin metallic silvery strip running along one of the edges inside of the case. 6" long. Has a black and red wire going from it into the drive PC board. And a yellow and black wire connecting both ends of this strip. Any idea what this strip is, or is for ? The label on the HD says: Seagate Barracuda 7200.11 750 GB P/N 9BX156-568 Thanks, B.
