Labeling Accuracy

Hard drive manufacturers round off their numbers in stating the capacity of their hard drives. For instance, 1 gigabyte actually equals 1,073,741,824 bytes, but hard drive manufacturers round the number down. Similarly, a hard drive labeled as a 250 gigabytes (GB) drive actually holds only 232.88GB.


Determining Free Space

On a Windows PC, you can determine how much space you have available on your hard drive by clicking on the "Computer" or "My Computer" icon, depending on which version of Windows software you are running. On a Mac, you can find your available hard drive capacity by clicking on the hard drive icon and then on "Get Info."
