I have an Acer Aspire 5732Z this has a DVD RW drive which I have used regularly but for the first time in 13 months I have trie to use the CD drive. When I insert a CD it is not recognised, the laptop operates under Windows 7.
Come on, we need a little more than that, none of us has a crystal ball.
Does the drive read DVD's? Have you tried other CD's? Does the drive show up in your device manager? What is on the CD you are trying to read?
