Comment on If I wanted to bury a hard drive for archival purposes (e.g. Country becoming Dictatorship), how to keep the contents from being damaged and where is the safest place to bury it?

How much better medium would be tape back up, or possibly Blu-ray discs. Either one would last a lot longer than a hard drive.

A so-called M-disk is rated for 1000 years. Artificial lab tests could at least ‘confirm’ a few hundred years. Amazing shit.

Add encryption to it, keep the keys safe (perhaps on another M-disk) and you’re set!

  Those are used by US government agencies, such as the department of defense for archival purposes. They are rated for 100+ years.

    Wut? They’re not extremely expensive, and they commonly have blue-ray capacity, so 50 GB
