Modern drives (where "modern" means anything made in the past 10 years I think) are set up in such a way that the inertia of the spinning platters will 'throw' the heads onto the parking area if power suddenly dies. This is not the same thing as intentionally issuing a park-head command, but the results are more or less the same.
