  1. Windows calculates space differently that most hard drive manufacturers.

    In Windows:

    1GB = 1024^3 bytes

    Hard drive manufacturers:

    1GB = 1000^3 bytes

    So a 120GB hard drive will only have 110GB of usable space in Windows. There must be a hidden partition on your hard drive for the manufacturers diagnostics or something similar.
  2. also remember that once a drive is formatted the File Allocation Table will take a space relative to the size of the HDD.
