*Windows-Problem*
use of binary-filesize, but shows decimal prefix.


Examples:

250 GB-HDD, Windows shows 250*109 / 230 = 232.83 GiB

2 TB-HDD, Windows shows 2*1012 / 240 = 1.819 TiB

16 TB-HDD, Windows shows 16*1012 / 240 = 14.552 TiB


(if your Windows displays, that your 1TB-HDD has ~931GB, everything is all right)
