My guess would that you only counted the size of the visible files. There's also hidden files/folders on your disk. Try counting with a different operating system like a one on a live disc.

I would use WinDirStat to detect which stuff are taking most of the space.

Are you sure it's detecting hidden files?

It's probably restore points or system images that windows has hidden, I'm not sure of a good way to find them though.

Apparently this is a bug with some gigabyte motherboards with an Xpress Recovery BIOS,  Some users have fix it updating the bios of the motherboard.

 

http://www.users.on.net/~fzabkar/HDD/HDD_Capacity_FAQ.html

 

"When the drive is first in the boot order, Gigabyte's BIOS will write a backup copy of itself to a small Host Protected Area (HPA) at the end of the user area. It then hides this image by reducing the capacity of the drive by a corresponding amount. Unfortunately a bug in the BIOS incorrectly adjusts the drive's capacity after creating the HPA. 1TB drives are reduced to 31/32/33MB, 1.5TB become 500GB, 2TB become 1TB, and 3TB become 2TB (not 2TiB). Smaller drives appear to be unaffected by the bug. (Note that if a 3TB drive is detected as 746GB or 2TiB, then that is a different problem, possibly a 32-bit limitation in the OS or BIOS, or in the driver for the motherboard chipset or SATA controller, or a 32-bit limitation of the firmware in an external enclosure.)"

Mystery is the source of all true science.
