They call it disk destroyer for a reason.

There's nothing specially destructive about dd. It's just a program that opens a file, and if you tell it to open a device file and it's got permission to write to it, it'll write to it.

You can just as easily overwrite a disk's contents with anything else that will open a file and write to it.

# cp /dev/urandom /dev/sda

will wipe your drive with random data in the same way that

# dd if=/dev/urandom of=/dev/sda

will.

Hahahahah I need to do that lmao!!!

Surely double checked is enough

Great advice. I rarely use dd, but when I do it always sends chills down my spine.

Lol, as someone who tried a bunch of different distros, I used the dd command a lot without ever realizing what could go wrong with it. I must have used up all my luck with that though, because somehow I ended up on manjaro of all things.

Did you triple check which device you picked?

I checked five times, actually. And then I check some more.
