I was using Nero 8, trying to copy a DVD; I interrupted the burn by pressing "cancel", but it seemed like it was still burning, and ejected the destination disk. If I put another dvd in the destination drive, would nero continue to burn to it, thereby, damaging it?
Don't use Nero anymore, but if you cancelled the burn and Nero kicked out the disc, it should be safe to put another blank in the drive... If you are worried, close Nero and reboot your PC.
