I recently acquired a Seagate Barracuda 7200 SATA hard drive. I bought an adapter to install it into an IDE system. There were no instructions. It came with an adapter board that plugs into the motherboard, a jumper for power to the adapter board and one flat 7 pin ribbon cable to go from the adapter board to the drive. Is this all I need or is there a cable for power to the drive that I’m missing.
