c.d. and dvd. drives to show

I installed a dvd drive as master and changed my c.d. drive to slave. They are on the same IDE cable. In the ‘My Computer’ window, it shows only my dvd drive. drive and I can’t get anything to play in my c.d. drive, but in the ‘hardware profiles’ window, it says both drives are working properly. Any help would be appreciated.
