Comment 1 Don Curtis 2017-07-27 09:39:57 UTC

Forgot to mention that, the DVD-RAM was in the 2nd drive: /dev/sr1.
--------------------------------------
Only for the case of an ext2 DVD-RAM in the 2nd (sr1) drive, the Device Notifier doesn't eject the disk.
If the DVD-RAM is in the 1st (sr0) drive, "mount" and then "unmount and eject" via the Device Notifier works as it should do.

Comment 2 Don Curtis 2017-07-27 09:44:58 UTC

With the ext2 DVD-RAM in the 2nd (sr1) drive, "mount" and then "unmount and eject" via the Panel's Device Notifier, followed by a bash CLI "eject /dev/sr1", cleans up the mount point and ejects the DVD-RAM.
