A few minutes ago, I had a CD in my computer which I was listening to. I switched the CD for another one, and it didn't recognize that CD. I tried 4 other CD's, and my computer keeps showing a little icon oc a CD next to my mouse right when the CD is put in, but then acts as if there's no CD in there. I recently has to reformat my whole computer, but these are all CD's which I had copied to my hard drive in the past, and they work on my actual CD player, so I have no idea what's going on with this. Anyone have a clue what's up?
