Hi...

a week ago I bought a new computer, all week I have been installing programs and such that I had recorded some CDs and DVDs, and now I've finally had time to put music on original CDs had, but the problem is that there are many original CDs that I did not recognize, do not know why, but the truth is desperate, specifically happened to me only with CDs of Madonna, nose if it has something to do, I repeat are original, and when I put in the PC drive D apreço me empty, as if there were nothing, however the original DVDs I have read with no problem.

My OS is Windows 7.
Would greatly appreciate your help, because I see no logic to this that I read some CDs and not others that are original
