If the old drive has "failed" & you are just replacing it in the box with the new one, why are you asking about cloning it?
Drop in the new drive, start it up & redo guided setup & you're good to go! Obviously since the old drive failed, you WILL also have to reprog any SP's & other scheduled recordings, since those are on the HDD as well.
