I'm just curious, did you ever try to format the drive as one partition? Any change then? Also, and perhaps more interestingly, did you check for contents of the drive with a utility like Whatsize, GrandPerspective or some such?

PS, I briefly considered the difference between decimal and digital byte prefixes (GiB vs. GB) and the numerical difference that might cause, but the implied inconsistent use of those prefixes makes that seem unlikely, and besides, the numbers don't match.
