At one point in Snowpiercer (the Netflix series)

a character sacrifices her life

to keep some hard drives warm (or room temperature) in a research outpost in the context of a snowy post-apocalyptic world where the average outside temperature is -100°C.

Was this necessary? Would the hard drives have been readable if they were simply left in the freezing temperatures (indoor and in a closed hardshell case)?

    $\begingroup$ After googling "can hard drives be damaged by cold temperatures", I found something that might interest you. Welcome to the world building se, be sure to make the tour and check the help center. A piece of advice: sometimes doing some research about what you want to ask can really pay out. You might even get the answers you were seeking in the first couple links you're shown if you're lucky. $\endgroup$ Apr 26 at 10:26
  • $\begingroup$ Are you asking specifically about how this works in Snowpiercer? Or for your own fictional world? Context please! $\endgroup$

    $\begingroup$ Hello George. Did you ask this on the right Stack? Here at Worldbuilding we help people develop the rules and systems of fictional worlds of their own creation. We specifically do not accept questions about 3rd-party or commercial worlds. Those questions are better asked at Science Fiction & Fantasy or Movies & TV. Keep in mind that when it comes to a story: character actions are chosen to drive the plot and science has little-to-nothing to do with it. In other words, when you ask "was this necessary?" the answer is "yes... the plot required it." $\endgroup$ Apr 26 at 14:50

    $\begingroup$ You would absolutely need to seal the harddrives from outside air. There might be problems with thermal contraction, but this is not likely for a device made to already survive more than 110C temperature range. the most likely is simple circuit board damage of the controller, and that would lead to easily repairable damage not data loss. The actual magnetic platters should be fine until they get superconductive, which will be under 2K. $\endgroup$
