I would just like to say I have had plenty of Samsung DVD-ROM drives that worked OK 1 minute and Broke the next with various symptoms .
No bios detection being one of them, another drive being recognised as Samslung ¬/$ in bios (or similar) to not being able to read DVD,s but Cd's being fine, no power at all on another one clicking noise could go on for a while as I have had about 20 of them go off their DVD -Roms do not last long IMO.
That command must also be in the samsung utils they release so If your convinced take it up with Samsung.
