Because Windows tells you the device is working properly doesn't mean that the Drive isn't damaged/broken or not working all it means is that the correct drivers are installed and there are no system conflicts. A dead Drive will appear this way if the hardware is correctly setup.
Now as to the current problem what Burning Software do you have installed?
Do you have more than 1 Burning Suite Installed?
What OS are you using there are many different versions of Windows that first appeared in 1995 so we need to know what OS is in use here.
If the Optical Drive is working the symptoms that you describe are what will happen with 2 or more Burning Suites Installed as they tend to conflict with each other and stop the Optical Drive working at all.
Also have you rebooted the system since this started? You haven't said one way or the other. You could have a Software Issue that is causing this and until you restart the software remains working in the background. Windows needs to be cleared by a Complete Stop and power down before it works properly again. So power down unplug the NB and pull th battery for 30 seconds. I don't think this is the problem but it's worth a try before doing anything else.
