Ah, the hardware manufacturers have brainwashed you well!  ;)  They'll be
so pleased.

Not brainwashed but not knowing what amtapetype was trying to do. Maybe we
should talk about physical and logical tape. The physical tape can only hold
~200GB, the logical tape can hold X depending on the data and the
compression scheam. Kind of like Nup printing, 1 physical page can hold X
logical pages.

No offense intended. It's just that for most *real* data I've seen, the 2X compression quoted by the industry is a fairy tale (never mind the 2.6X Sony quotes for AIT these days).
