Hello. Well every time I pop in a music cd or any kind of cd into my computer, it won't show up and play. I can't find the location of the drive or disk where it's supposed to be located. I open the windows media player, pop in the cd but nothing happens. So I try to open it manually by looking under the names of the drives and in the control panel but it's not there. It's been that way since I defragmented the files, but I'm not sure it caused it. Can someone help??
