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.
Not yet, but I live in fear.
I did make the mistake of mounting a drive while I was in the middle of formatting another one. It just halted the operation so it wasn’t too bad, but I try to be more careful now.
