My son's CD drive occasionally throws errors saying that it cannot read CDs in the drive. Usually the message says 'please insert a disc in drive D, although sometimes the PC will appear to freeze. The problem appears to be intermittant except with certain CDs which it refuses to read at any time. With some Cds it will happen occasionally, whereas I can read them fine on another PC.
Thinking this would most likely be a faulty drive I tried replacing the drive with another (working) DVD drive. However the problem still exists. Any help please?
