I can't seem to get tapetype to agree to the rated capacity of my
Powervault 120T (DLT 7000 35G native).
The maximum uncompresses that tapetype registers is about 27G.
Running 'mt status' returns a density code for 35G.
Any ideas why I can't detect the full tape?
Here's the output from tapetype.

Not the faintest idea. I would believe amtapetype to be correct
for your current setup. Maybe you have to fiddle with some setting?
Or do you have the correct media inserted that has 35 Gb (some
manufacturers supply different tapes that just differ in length,
hence the capacity difference). But 27 Gbyte is really a weird number.
While tuning/testing know that it runs *much* *much* faster if you
give amtapetype a realistic estimate, like stated in the manpage.
