Have an xp Corp system with a yamahaa burnner and an ncr ro/cd. The burnener is always searching for what I have no clue.Doesnt matter if there is a disk in or not, doesnt matter if any programs are open or not. About 15 mins after start up it just starts searchin and slows or stops whatever program you are in. I have already lost my hair trying to figure this out. My head is next, Can someone help please
