Like I’d imagine there’s gonna be a lot of rain over time if I want this time capsule to last like idk 10 years? 30 years?
Is there like a box so tough its indestructible?
Can animals dig it up if I bury it?
How deep do it bury it?
Is the earth’s magnetism gonna affect the hard drive? (Or is there a better medium?)
Like I want this to be like very low budget, I don’t have millions to build an actual timecapsule like some organizations have done. Is there some cheap box that’s waterproof to protect a hard drive from damage for like 30 years buried in the ground?
I think if you want 10+ years with high assurance you probably want to burn the data to archival quality BD-R disks (not the dye based ones)
The right spinning platter hard drives might have a decent chance to make it 10 years but there’s a lot of possible failure modes and also a decent chance that when you try spinning it back up it gives nothing but read errors.
For cases for “only” 10-30 years I might pick a pelican-like case inside a makeshift wooden coffin-like outer layer. For longer I’d probably use a metal box like an ammo box inside the plastic case and a stone outer layer instead of wood
You would need to investigate the soil you put the wood in, in order to select the correct wood and wood treatment. The wrong kind of wood in certain soils can be broken down in weeks to months. Getting wood to last years is tricky and depending on the soil could even be impossible.
An ammo box is probably cheaper than a pelican case. I’d go for that no matter what.
