I'm fairly sure that there's no program using the cd-recorder, since cdrecord finished with an error code. Furthermore, the disk isn't mounted, so nothing could be disiplaying the content...
On exiting cdrecord says something about ...scsicmd: prevent/allow opening...
or the alike. I guess this has something to do with it.
Is there a way I could find out if an application uses the cdrecorder?
Even if so, is there a way to just eject the thing, no matter what? like eject --force ?
