My computer is about 6 months old. It has one cd drive (which is working fine), and one dvd r which i was previously only using to burn music cds from itunes and copying cds using a quick burn program. This last 2 months though it (DVD R) wont even read a cd. If i put a music cd in there, (or a blank cd) it wont show up that there is even a cd in there. as soon as i put a dvd in there it is fine and starts playing the dvd. I have completed all the troubleshooter ideas, I.e deleting the driver and restarting the computer so it installs it again. Tried to update the driver, etc. It shows that the driver is working fine. Any ideas please?
