My friends computer does not show his cd or dvd drive in my computer. The icons are not there. It shows them in device manager but thats it. And they have a exclamation point next to them that says the device is not working ect and the driver may be wrong. So when I try to install the driver it says no device was found for that driver and it will not let me install it. The jumpers are set correct, one on slave and one on master. But for some reason nothing wants to work. Any ideas on how to get these drives to work? Or show up in my computer.
