My friend recently gave me a music disc and I inserted it into my laptop just like any other cd. Only this time, it didn't show up in my computer and It did not even recognize that a disc was even in the drive. To make matters worse, I cant even eject the disc. I push the Fn+F7 keys (The eject sequence for my laptop) It shows the eject image on screen, but the disc doesn't eject. Please help!
