How to preserve HDD longevity?
(alien.top)
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
Really nothing you can do except be sensible. Don't move them while they're powered on, and keep them in a mild temperature and relative humidity environment comfortable for a human. That's about it.
Just have a backup. And a backup of your backup. That way you don't have to worry about it.
