about 50% of the time after starting my machine my cd burner isnt recognized. so i go into device manager and hit the scan for new plug and play devices then windows finds it. or i can go into add new hardware but sometimes it says that another device is being installed but it never recognizes it. it is a plextor 12x10x32a and i am running a 1ghz pIII and a full install of xp. this is my second install of xp and the first install did the same exact thing.
