Could just be the rounding up of half full sectors, etc. after the reformat.

If you check around, lots of people complain about that when they purchase a new drive and find out that their 320gb drive doesn't seem to really have 320gb listed as free space.

Some of your drive area may not be actually full of data but there ya go.

You could try a defrag on the drive and then compare, but I doubt it will change all that much.
