The driver needs to be reloaded. It may still be in the Dell Utilities Program, the Dell Drivers File, or it can be downloaded from Dell's website. Go to Control Panel/System/Hardware Manager and drop down to CD Rom Devices. Right click on your product and click on drivers/update driver. If your device isn't listed there go to install hardware in control panel. You might want to swap the CD rom unit with a known good one. On three occasions I've had the CD Drivers be OK, but the Windows drivers were corrupted. Had to reload the operating system completely to make it all work again.
