My mother has a number of CDs that she has purchased directly from musicians at their shows. Some of these CDs are CD-R. She can read them on the home CD player and in the car. Now she intends to get a new car which has no CD player but a USB input. I am ripping her collection of CDs using ExactAudioCopy (EAC). These CD-Rs cannot be read by EAC, nor any other program on my laptop. ImgBurn claims that the CD-Rs are empty. There is no way to determine what was used to write these CD-Rs. I am tempted to use ImgBurn's Close track/session/disc feature but am hesitant to do so because I might stuff up her discs so that they do not play at all.
Does anyone have any ideas? Is this just bad luck and nothing can be done?
