What do you do if your computer is not recognizing your CD Drive?

See if all the plugs are plugged in correctly. You could try to change the places of your hard drive and CD-drive since they use the same plugs, I it does not you should buy another CD drive and try, it still doesn't work? Contact the manufacturer of both your computer and CD-drive.

If you think that the id cable or port is damaged then try to check the cable or port in hard disk port.
