Description sworddragon2 2013-05-17 10:55:26 UTC

I'm trying to lock the tray of my optical drive to prevent any ejecting if I'm hitting the eject button. This is the current state:

root@ubuntu:~# cat /proc/sys/dev/cdrom/info
CD-ROM information, Id: cdrom.c 3.20 2003/12/17

drive name:		sr0
drive speed:		102

Can open tray:		1
Can lock tray:		1
Can change speed:	1

root@ubuntu:~# cat /proc/sys/dev/cdrom/lock
1


On pressing the eject button the drive will still do an eject. I remember earlier my drive was successfully locked from an apllication so the entry 'Can lock tray:		1' seems to be correct.
