Plug in the disk drive.
Now while holding down the windows key (between [Ctrl] and [Alt]) press the
[Pause/Break] key. Select the 'Hardware' tab and then the Device Manager
button. Now look to see if any of the devices have a yellow '!' icon over
them (particularly a disk drive or an unknown device). If you have, right
click on it a select 'unistall'. Close the device manager. Now unplug your
drive and after a few seconds, plug it in again. With luck it should
install as a new device. With a lot of luck, it should work.
