Here is a list of things you can do if your CD/DVD drive is not working correctly:

1. Check the power cable for the device and make sure it is securely connected.
2. Make sure that the disc is not scratched or dirty.
3. Check to see if the drive is recognized in your computer’s Device Manager.
4. If it is not, try a different port or try switching out the cables.
5. Uninstall the device from Device Manager and then reinstall the device.
6. If none of these steps work, you might need to replace the device.
