Hello Pablo, Here is an explanation from Wikipedia of what you're seeing.
Cheers, Anne Since the early 2000s most consumer hard drive capacities are grouped in certain size classes measured in gigabytes. The exact capacity of a given drive is usually some number above or below the class designation. Although most manufacturers of hard disk drives and flash-memory disk devices define 1 gigabyte as 1 000 000 000 bytes , software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by 1 073 741 824 (2 30 = 1 gibibyte ), while still reporting the result with the symbol "GB". This practice causes confusion, as a hard disk with an advertised capacity of, for example, " 400 GB " (meaning 400 000 000 000 bytes ) might be reported by the operating system as only " 372 GB " (meaning 372 GiB). Other software, like Mac OS X 10.6 and some components of the Linux kernel measure using the decimal units. The JEDEC memory standards uses the IEEE 100 nomenclatures which defines a gigabyte as 1 073 741 824 bytes (or 2 30 bytes). The difference between units based on decimal and binary prefixes increases as a semi-logarithmic (linear-log) function—for example, the decimal kilobyte value is nearly 98% of the kibibyte, a megabyte is under 96% of a mebibyte, and a gigabyte is just over 93% of a gibibyte value. This means that a 300 GB (279 GiB) hard disk might be indicated variously as 300 GB, 279 GB or 279 GiB, depending on the operating system. As storage sizes increase and larger units are used, these difference become even more pronounced. Some legal challenges have been waged over this confusion such as a suit against Western Digital Western Digital settled the challenge and added explicit disclaimers to products that the usable capacity may differ from the advertised capacity.
