That's obvious. You have the same effect on any other OS, too. If the drive is in use, which is the case if it's mounted, the CD can't be ejected, because the CD-ROM drive locks its tray. If you haven't mounted the CD then the drive is not in use, so you can open and close the tray as much as you want and the way you want. I don't know exactly why eject can open the tray if the CD is mounted. Maybe because it first umounts the CD. Heiko
