Follow-up from "Dumbest Thing you have done distro-hopping?".
Here's mine - the laptop from which I'm typing right now has a broken touchpad that keeps jumping and clicking randomly, and does not work. Well, I can't afford to fix it, but at the moment, I was so pissed off I punched the touchpad really hard, and the machine panicked with all the lights blinking. A few more revival abuses, and the machine was back to life, but since I was running a nixos-rebuild switch --upgrade in the background, I blew off my boot partition. I think I just broke the unbreakable distro.
I had an old arch install about 7 years ago that stopped booting, so I booted into ubuntu, mounted the ssd, used a chroot to fix it, forgot to unmount the ssd, proceeded to rm the mount dir as it was "temporary". It took me mere seconds to realize what I did and by then it was a lost cause. I was able to use a file recovery tool to grab my precious memes, but thankfully there wasn't much else valuable on the drive.
