The problem that we were referring to was due to the physical absence of
hardware to check for a media density hole. What BACKUP could/would do
was to read what was previously recorded. Once formatted, the density was
easily recognizable by whether a read was successful. But the lack of a
sensor meant that FORMAT did not have a clue.
