I put the data CD, close the tray, try to mount it, but [karol@white ~]$ sudo mount /dev/sr0 /media/cd/ mount: /dev/sr0 already mounted or /media/cd/ busy
It's definitely not mounted, let's try again [karol@white ~]$ mount | grep sr0 [karol@white ~]$ sudo mount /dev/sr0 /media/cd/ mount: block device /dev/sr0 is write-protected, mounting read-only
OK, let's see if it's mounted indeed [karol@white ~]$ mount | grep sr0 /dev/sr0 on /media/cd type iso9660 (ro)
Looks fine, unmount it and eject it [karol@white ~]$ sudo umount /media/cd/ [karol@white ~]$ mount | grep sr0 [karol@white ~]$ eject /dev/sr0 eject: unable to eject, last error: Inappropriate ioctl for device
Despite the error, the CD got ejected. Using eject is the only way to do it - pushing the button on the case doesn't to a damn thing ... unless I push it and try mounting again - in this case, the tray will open.
Since when do you have those issues? It's probably a bug in the kernel (package linux 3.0.2 and 3.0.3). I just wanted to try what was explained in this thread and must realize that my DVD writer isn't detected anymore, no /dev/sr0 anymore. And my drive is hard locked, means I can't open the tray anymore with the drive's eject button. And the eject command doesn't work either, of course. Here's my bug report: https://bugs.archlinux.org/task/25649 Heiko
