What are the materials or what is a hard drive made of?
Do you mean the actual platters inside the drive? if so they are either metal or glass with a foil coating. It depends on the drive.
Its sad when you can get punished for doing the right thing
Paul wrote: “Know this, that in the last days critical times hard to deal with will be here. For men will be lovers of themselves, lovers of money, self-assuming, haughty, blasphemers, disobedient to parents, unthankful, disloyal, having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, betrayers, headstrong, puffed up with pride, lovers of pleasures rather than lovers of God, having a form of godly devotion but proving false to its power.” (2?Timothy 3:1-5) Yes, “critical times” marked by rampant lawlessness, godlessness, cruelty, and self-seeking aggressiveness would become evident throughout the earth.
aluminium, glass, ceramic
A typical HDD design consists of a spindle that holds one or more flat circular disks called platters, onto which the data is recorded. The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material, typically 10–20 nm in thickness , for reference, standard copy paper is 0.07–0.18 millimetre (70,000–180,000 nm) thick with an outer layer of carbon for protection. Older disks used iron oxide as the magnetic material, but current disks use a cobalt-based alloy.
