Scenario:

You have a computer it can be running windows server or windows xp / vista / 7 doesn’t matter. You suddenly notice that your CD/DVD drive is missing.

 


Problem:

You have done what any IT guy/girl would do and uninstalled the CD/DVD ROM from the device manager and rebooted, yet you still get the same code 39 error. You have tried swapping for a new CD/DVD ROM and you get the same error.
