Hmm, then there is the issue that an active scanner will avoid me from removing the media again. Most annoysome when the machine won't promptly give back the disk. Imagine me browsing through a stack of unmarked dvd-rw media trying to find the one with the right file on it, but having to wait every time for the whole media to get scanned..
