I have a 3 week old NEC ND2510A dual layer burner that is no longer reading any type of disk. Windows is still recognising the drive. If I try exploring any CD or DVD the explorer window shows the drive as empty. My dvd player is still reading disks fine. I have made no hardware or software changes. I am running windows XP. Will this more likely be a hardware or software problem? Can a problem with the OS stop the NEC reading disks?
