Comment 31 for bug 28835

@Scott Not every optical drive has an eject button: some are under software control (but may have some little pinhole into which one may insert a paperclip: I don't think this sends a software-detectable event). Also, my use case (A): rewriting rewritable media may require the ability to unmount, but not eject optical media.

@dael Thanks for the extra use case for unmount-without-eject (multiple partitions). The current UI to remount unmounted partitions is a little odd in nautilus (visit "Computer", activate parition icon, wait), so I'd argue there's no need to add a special "mount" feature (it's either already there, or we confuse the current distinction that "Places" or "Computer" may contain unmounted volumes, while the Desktop typically contains only mounted volumes). That said, making this more discoverable may be interesting.
