    My computer's specs state that the HDD's capacity is 320GB. However, when I go to My Comp and Right click on my two partitions, the total GB actually comes to a little under 300GB.

    Why does it show up like this? Just curious.

    This is normal. The hard drive manufacturer Uses a Decimal 10 math when they advertise the size of of their drives. When they say 320Gb they are using the 10base number. How ever your computer doesnt use a 10 base number. It uses a binary number which is reallyonly 2 digits. 1 & 0 1 represents on 0 represents off. When figuring the size of a hard drive using the binary system, you have to remember that 1 Meg is actually 1024 Kb. do the math that way and you will see that your drive is actually showing up the correct size in binary. Also a certain portion of the drive size is used as overhead for the file system formatting.
