Optical drives never require a driver when used in any Windows os from WinME & up. Windows XP, Windows Vista, & Windows 7 all provide native support that allows an optical drive to read a data or music disk and to burn a cd-r disk. No support for playing dvd disks, avi or mpeg video files, or for burning cd-rw or dvd disks. For those tasks, compatible 3rd. party recording & dvd decoding software is required.
All modern external USB optical drives are plug and play in all Windows OS's beginning with Windows ME. All that's required is a working drive and working USB port.
