Well First of all scandisk, defrag, and anti virus arent gonna do shit for you having a burner problem. Find out the manufactuer and model # of your CDRW. Lookt it up, make sure its compatible and get the XP driver. Completely remove it from your device manager then install the driver. If that doesent work, make sure you have all the jumpers set correctly, cables are plugged all the way in, etc. Also, make sure the material your trying to copy doesent have copyright protection on it. If that is the case I would suggest using better burning software. cloneCD is good. nero is too.
