We cannot do these things macroscopically, no. I will repeat my protest which you ignored from the previous comment. 1) We have never reduced even a single atom to absolute zero. Practicioners debate whether it's actually possible. 2) Your discussion of bose-einstein condensates is neat and all, but the explicit context is a hard drive. Nobody has ever condensed a macroscopic object (the breathless article about condensing a tardigrade isn't actually correct.) There has never been a superfluid or superconductive hard drive. Please focus on the question being asked, in the context being asked, if you must reply. How do you propose to reduce a hard drive to actual non-almost zero degrees? Not a few particles, not electron pairs. A hard drive. Once it's at absolute zero, formally, so what? Yes, I saw you guys handwaving "spooky stuff happens," but in reality, we've had hard drives within a tenth of a degree kelvin and nothing happened. If you're going to propose effects, please have a specific mechanism in hand that creates the specific effects asked about, in a context that is the hard drive and not two electrons Thanks

The CERN CMS magnet is a 10,000 ton superconductor. 6-meter diameter and 13-meters long. For the vast majority of materials (of any size), strange things do happen when you hit the critical temperature. You can take any amount of mercury for example and when it hits 4.1 K it loses all its electrical resistance. Hard drives are not the only items that can contain information.

  A third time: 1. We've had hard drives within a tenth of a degree of kelvin, and the effect you're asserting did not occur 2. You're offering no explanation for what would actually cause this 3. The weight of a random superconductor is an irrelevant detail added for fake technical acumen We have had these devices at these temperatures, and the thing you're talking about did not occur. Until you can say why it would, there is no reason to take this seriously. We've already done this. Your speculation is invalidated by experience and data.
