First Thing to check would be if you have the device in the list. If you are not showing any "DVD/CD-ROM Devices", there is a problem with the computer hardware. This may or may not be fixed in the System Bios during Boot.
Second thing to check would be if there is a yellow icon on any of your devices. Windows Update usually repairs the devices with this yellow icon. If there is a yellow icon on any of your devices then assuming you have run Windows Update, Windows Update is not sure what to do. Remove the device and then reboot. After rebooting windows should try setting the device back up. If windows cannot setup the device automatically you will need to provide drivers.
Control Panel > System and Security > Administrative Tools > Create and Format Hard Disk Partitions
Third thing to check would be if windows is assigning a drive letter to the drive. If there is not a drive letter assigned to the drive. Right click on the drive and then choose "Change Drive Letter and Paths" to assign one for the drive.
