And potentially one more question from a list lurker, Ted. Where are the tools that allow us to check and/or adjust that? I ask since I have 3 of these terrabyte drives in this box now and have no clue how to either check to see if we're off, or how to fix it if it is. And I have called my self following this discussion without noting if the tools have been specifically named.
