Optical drives never require a driver when used in any Windows OS beginning with Windows 95. And I believe the same holds true for Mac OS's. Since you think the OS is not applicable, I don't see any way to help you. Begin by saying if it's Windows and what version. And if it is Windows, please say whether the drive is listed in My Computer and Device Manager.
