When you buy a disk it is usually not formatted, and cannot yet be used for storing data. When you format the device, you will notice that the free space on it is less than the original size. This is due to the fact that some space has to be used to make the device usable; this space is occupied by the filesystem. Also, disk manufacturers often use a different standard to measure disk capacity, which results in a further discrepancy.
