I need some help with the cd drive on my pc. I am burning new disc on the system but it fails to read by the system. I am having a dvd drive which is not very old. I checked in device manager. There is no issue with the driver or any hardware fault. i am using Windows disc burner to burn the cd/dvd. After burning the drive when insert them back in the system it not readable at all. What should I do. I had already wasted around 4 dvd's just in testing. What should I do here.
