Empty 4TB Seagate Drive Has Quite A Lot Used

I couldn't work out the ideal forum here for this question so I have put it here in the Mac Pro forum because that is the nearest.

I have just put a new 4TB Seagate Desktop HDD.15 drive into my Mac Pro. The big 4TB hard drive is completely empty, but ProSoft's Drive Genius 3 tells me that 682.89 MB is Used. I know there is always some space already used but 682.89 MB seems like a lot to me. It is 0.02% of the total drive capacity.

I wonder if that is a normal amount of drive space to be already used up by one of these big drives?

Thank you.
