We get 60MB on the DC600A cartridges at work. All my cartridges are DC600As.
No DC300s or DC450s. Got the same amount on a DC6150 I tried, too.

Nope, not sure at all.

Well, if someone comes up with info on that I'd like to know about it.
I would have assumed it'd use the highest density the tape supported,
and the MT02 is documented as being able to read the tape density info.
