I bought another dvd burner and once its in my old one doesnt work anymore. screenshot Should says NEC not OEC, Shows up this way in the BIOS as well. Lite On works just fine but the NEC doesnt work when lite on dvd burner is plugged in. So I have it disabled right now it makes the system run slower with it enabled. why ? I was thinking its cause they're on the same cable but ive had dozens of other drives on same ide cables without problems but never had dual dvd burners so maybe thats the difference?
