I don't think any commercial HDD can stand this range. There may
be militaty equipment with this range, but I doubt it. Possibly the
only choice is to add a heater that keeps the drive at or above 5C
or so. E.g. Maxtor says 5C...55C operating and 0C...60C operating without
massive impact on reliability.

On the other hand, non-operating most HDDs can stand your temperature
range. Again, Maxtor says -40C...70C storage temperature range.
Of course you have to look into the manual/datasheet of any specific
drive to be sure.

it may be possible to construct an elaborate gadget using thermometers,
a thermostat, and a compact heat/cooling source like peltier pads into
an enclosure for the drive that could bring it to an acceptable
temperature before turning on, and keep it there until it was off.
but that'd be a project for only the most die-hard geek.

If that's "storage temperature" most drives on the market will handle it.
If it's "operating temperature" then you'll looking at military
hardware--google "ruggedized hard disk" and you'll find a bunch of
hits--you'll have to call for pricing and you'll want to be sitting down
when they tell you.

There are a number of fairly inexpensive 12v cooler/warmers on the market
that use the Peltier effect, some of them sized for a six-pack--one of
those should hold a couple of drives nicely. You should be able to tweak
the thermostat on one to keep your drives in their normal operating range
without too much trouble. I'd want a dual electrical system in the vehicle
though, with a separate battery for the coolers and the like so they don't
run the starting battery down.
