I remember a case some years ago when they had a CD burner and this one would react to some standard ATAPI flush_cache command with a flushing of its firmware and brick.
Iirc Mandriva used that command to check if there was a burner or normal cd reader, and LG loudly stated "we do not test our hardware with linux" and things like that.
Seems to have changed since then. Well, I see that with confusion but also some joy. (umm, there, it was 2003, okay, 7 years to change their mind, well, why not.)
Stop TCPA, stupid software patents and corrupt politicians!
