Oh common. I objected to you saying that all energy drawn gets transformed to heat. That's patently false, unless the system you're studying has either efficiency 0% or is indeed a heater of efficiency 100%. Anything in between contradicts what you said. In the specific case I've objected to is even easier to see the problem. The HDD platters spin. That's work done. Energy transformation from electric to kinetic. Whether its quantity is bigger or smaller than that that gets transformed to thermal energy is a matter of efficiency. Otherwise the kinetic one would be free and Perendev and Bedini would be inclined to post here.
