No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

So I learned that if a MicroSD card gets snapped in half, its unrecoverable.

Okay, so suppose you were in war, and enemy soldiers were about to raid you. You just snap the cards in half and the data is un-recoverable, right?

Why are you so concerned about the destruction of data? This is the 3rd post in 2 days from you along these lines

Lol, sorry I just get obsessed with data archival and related things. ๐Ÿ˜‰

Whatever floats your boat, I suppose. To answer the question, removable data storage is fine in general, but in my experience microsd cards can be a little unreliable for the long term. Just make sure the silicon breaks to destroy e

No, but you can smuggle them by eating them.

Recoverable. And this makes your situation a lot, lot worse.

As long as the silicon got snapped and not just the softer plastic around the silicon.

If it's actually important data that a nation state would want, most of the data could still be read off with an electron microscope.

So what you're saying is that, its recoverable, just not by the average data recovery company.

Your best bet would be to shred the data multiple times (for example with the shred command) and then break the card physically. But shredding takes time so I guess that's not very applicable to your case.

If you have a lighter, you also can try to melt the SD card's insides. That should be impossible to recover.

In any case, you should keep it encrypted all the time and only decrypt it on the fly. For example with LUKS2.

At that point chewing on it might be your best bet

Soldiers don't look for your sdcards, they shoot people. If you are planning on moving through block posts where your things are cheked it's better for you not to have weird sdcards either broken or not. But you can have one in your phone. There are ways to hide encrypted data so it won't be detected e.g. veracrypt hidden volumes.
