What's the cheapest way to protect an external HDD from things like solar flares and EMP pulses? I periodically save all my data on an external HDD, so I may as well make it a proper digital doomsday vault. I have shittons of tinfoil, if that's any good. The HDD won't need to be opened more than maybe once a year, so it doesn't have to be as sleek as the expensive commercial bags.
I built a shed out of car batteries. The door was difficult, but works, and the roof required a large number of I-beam support columns spaced at 24". One awesome aspect is that it's way more soundproof than anything I've tried before, so I pretty much live in there now.
Initially it was only one row of batteries, but I found that I needed 3 walls to stagger them correctly so that it could block the EMP from a nearby thermonuclear blast.
how cool is that? as close as i ever came to that was building a car battery out of sheds. similar, but not really an apples to apples comparison, though.
>a shed out of car batteries
How did you acquire them? Pulling them out of the ocean? Offer $10 a head or something?

I can't answer your question, BUT...
Don't save data on a (single) HDD. Drives are mechanical devices and will eventually fail.
Get a small two-drive USB RAID enclosure and throw two HDDs in it
Then if one fails you have redundancy
I use a four HDD RAID NAS as my primary file server, then a two HDD USB (pic related) backup for important things in case the NAS fails.
Of course, if my house burns down, I'm screwed ... that's why a cloud backup is also a good idea.
a microwave unironically
let me guess thats a 10 cent mylar bag sold for 25 freedom bux.
Ammo can. As long as it's metal and grounded and the contents aren't electrically connected to it (should be putting foam in their anyway -- and NOT antistatic foam, because that IS conductive,) you're good to go.
Faraday cages need to be grounded?
>Faraday cages need to be grounded?
No. But you're looking for EMP protection. It will be more effective if grounded.
Better to burn any critical data to disc; like a DVD or Blu-Ray. I have around 12TB of data on my hard-drives but really only a fraction of it is irreplaceable. A single BDXL M-Disc can store 100GB, would be impervious to solar-flares and electro-magnetic pulses, and is supposedly "lifetime archival".
