As I did write _many_ times, this was done by the program "cdwrite" on Linux in 1995 and as cdwrite did not check whether if actually got a CD writer, cdwrite did destroy many hard disk drives just _because_ the /dev/sg* is non-stable.
People did not believe this and did write shell scripts with e.g. /dev/sg0 inside and later suffered from the non-stable /dev/sg* <-> device relation.
