I’ve been getting into single board computers, and I’ve overwritten my external hard drive twice now trying to flash OS images to SD cards from my Linux PC using dd (good thing my important data is backed up). To be fair, it’s totally my fault, but I’m curious if anyone else has done this.
It never happened to me thankfully, I always check with lsblk first. Otherwise if you usually write distros to USB or SD cards, you should probably use safer tools, some have nice GUI.
