My liteonit Cd writer will only work if the speed is set to 8x. This is a new development. If any other speed is chosen, you can hear the drive spinning forever. Task manager shows nothing running to stop. Only remedy is to shut down in order to open the drive door. I have Win XP, Pentium 3. Upgraded to Nero 6 in case it is a software problem--same outcome. Any suggestions would be welcome.
