Apparently it's nothing to do with that and originally comes from "data definition" though.

- GTP 6y agodd is also known as "Data Destroyer", because it's easy to make a mistake and overwrite the wrong device. This actually happened to me once, but I still use it when I need to write an ISO to a USB drive anyway.
- RMPR 6y agoAn advice that was mentioned many times in this thread to avoid writing to the wrong disk. Use the symlinks in /dev/disks/* instead of /dev/sd* directly. Since they are more intuitive, using them will likely reduce the odds of you making a mistake.
- MaKey 6y agoJust avoid using /dev/sdX, use /dev/disk/by-id/ instead.
