click on folder options, and turn on visability for hidden and system files...

sometimes system manufacturers use a partition for a system restore function also.

You also need to allow for the formatting of the drive.

Depends on what it's counting.

Also depends on the sizes of files on the system and what units of disk space are used for allocation. (So if a file takes so many 32K allocation units with 16K left over then you have 16K wasted - so lots of small files means lots of wasted space).

And then you have the space allocated to directories/folders and the file meta information (dates, access rights).

And on top of that NTFS will maintain a journal of transactions on part of the logical disk.
