My laptop bit the dust and I got myself a PC. Rather than copying everything from the hard drive of the laptop to the PC, I just want to use the hard drive froum the laptop as a slave drive in the PC. Having watched some YouTube videos I now understand how to do it. I know that I need to get a data cable cause I don't have an extra one. I have One going to my existing hard drive and one going to the DVD drive. But I don't see any place on the board to plug in another data cable. The two existing cables are plugged into the only two ports that there are. Am I missing something?
