Hard Disk recording at higher elevations

["mike.rosenlof" mike.rosenlof]

Hard drives and their mechanical moving parts may be different, but
the usual reason for specifying a maximum operating altitude for
electronic devices is that air cooling works less well when the air is
less dense.  This is "typically" only an issue when you're close to
the upper limits on ambient temperature as well as altitude.

YMMV, of course.
