First, try not using cable select. jumper the DVDrw as the master at the end of the IDE cable and the other as slave. Make sure they are connected to IDE secondary channel and use Ultra DMA 80 wire cable. If it still fails, go into device manager from system in control panal and find the secondary IDE channel and delete it. Don't worry, after you reboot the system will find the channel and rename the dvd drives. If that doesn't work we're are going to have to remove the upper and lower filters in the registry but not yet. Try that first an see what happens.
