John/Jason,

The GetLogicalDriveStrings function will only return a list of drives available. You will next need to use GetDriveType function, again in Win32API to identify the type of drive. If it returns DRIVE_CDROM, you then have the drive letter of the CDROM. It may be quicker just to scan drives A to Z with this function - need to manually test to see if error occurs on non existent drive. Then stop when you find CD.
