Hard disk drives are described andadvertised by manufacturers in terms of decimal(base 10) capacity. Microsoft Windows and otherprograms, such as FDISK, use the binary (base 2)numbering system.In decimal notation, one megabyte (MB) is equalto 1,000,000 bytes, and one gigabyte (GB) isequal to 1,000,000,000 bytes. In the binarynumbering system, one megabyte is equal to1,048,576 bytes, and one gigabyte is equal to1,073,741,824 bytes. Because of the differentmeasuring systems, you may see a differencebetween the size reported by Microsoft Windowsand the size advertised. The storage capacity ofthe hard disk drive is as advertised.Microsoft Windows reports smaller capacity in theWindows Explorer tool and in the computerwindow because it shows information about onepartition on the hard disk drive at a time. One ofthe partitions contains the System Recoveryinformation.
