Hi - Can anyone help please? My CD/DVD R/RW drive will open shop bought CDs (with programmes on) but will not open CD/Rs that I have written to in the past. Also, I cannot write to the CD anymore. What's wrong? I last used it successuflly with iTunes but then a second burn of music wouldn't work and it has been as described since. I have checked the driver and nothing better is available. The built-in Toubleshooter cannot help and it reports the drive working OK. Appreciate any advice. Thanks.
