    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Actually, they only hold about 500,000,000,000 bytes (more or less) which when divided by the size of a gigabyte (1024x1024x1024 bytes) produces 465.66GB, which is close to what Windows and Linux show. Since drives are a fixed number of cylinders of N sectors of M bytes each, you will never get exactly 500,000,000,000 bytes, but a bit more in all likelihood. IE, in disc marketing terminology 1 gigabyte < 1GB
    Sometimes, real fast is almost as good as real time.
