Corrupting an SD Card

>>59533040
Give it back Tyrone.

>>59533040
sudo dd if=/dev/urandom of=/dev/sd*

replace the * with the letter for your SD card.

this'll basically write random data to the whole thing.

>>59533040
Couldn't you just shred the device file?

>>59533040
Toss it in the microwave for a few seconds. That should do the trick.

>>59533040
You don't just want to delete all data on it by writing random numbers to it? If so, just use bleachbit or whatever. That will actually delete all data on it.

If you really want to corrupt, try looking at the hardware spec sheet for your SD card and providing it 5V higher than the max? Then do that to each pin?

Couldn't a format fix that?

...why?

What kind of effect you want to give? you want to still show the files but make them fail to open or do you want to make it look like all the information was lost?
If you want the first one try with a program that encrypts files to give an effect similar to ransomware, this way when the person opens the file there'll be just gibberish.
If it's the second one >>59533058 is a good answer, you can use /dev/zero but it'll be obvious you did it on purpose.

basically I haven't been keeping up with some medical stuff I was supposed to keep up with and they are requesting i turn in the sd card that collects data on a medical machine so they can pull it. I dont want to hear a big stink about it so i just want it to look like the data was corrupted or card broken so i can start fresh.

20KB, 600x300px

Just what kind of data do you have on that sd?

>>59533040
heat it up to 150C for an hour

Download torrents to the sd card. Broke quite a few doing that.

open the card and cut all the traces on the PCB with an x-acto knife. they'll plug it in and nothing will show up.

Write data to it continuously. Memory-card flash is good for under a thousand write cycles.

>>59533040
sudo dd if=/dev/random of=/dev/sdcard bs=512

>>59533549
Yeah, someone else posted something like this earlier, I have no clue what that means. You guys wanna talk guns, or air traffic control then I'm all for it, but this is foreign to me.

>>59533580
TERRAIN PULL UP

either use a hex editor to corrupt one file at a time, or write random garbage over all sectors at least 3 times

>>59533603
LOL, that's more of a Resolution Advisory(RA) from a TCAS, that would go to the pilot from an on-board computer but yes, its ATC related.

>>59533040
for most normies this will do the trick
just fire up linux and make more than one partition on the card

>>59533040
If you want to destroy it smash it with a hammer.

If you want to erase it then erase everyone on it then fill it up with who gives a fuck to overwrite the data.
