Auto swallow and eject cd (from the commandline)

I am trying to close and eject cd from the commandline. The purpose is to rip a lot of audio cds with abcde . I use eject and eject -t commands to open and close the cd drive. I mount my cdrom with this line in /etc/fstab: /dev/sr0 /media/cdrom0 udf,iso9660 user,noauto 0 0 The problem is that ejecting the cd means also to unmount it. After the unmount, there is no way to close it. When I start the computer, eject -t works and closes the tray. But if I open it again (with eject) eject -t does not find /dev/cdrom because it is not mounted (the tray is open and there is no cd mounted). Someone sees a simple solution? P-S : Debian (unstable) system.
