We had 10" drives in our test rack tied to an HP 1000 minicomputer that had
both removable and fixed platters. They weren't crash proof but were
replaceable in the shop, no dust room since there was positive airflow through
the drive unit. You didn't dare sweep the floor though! As far as head
calibration you were looking at a very expensive set of instruments for this
and the platters alone were costly.
