    Absolutely nothing to worry about.

    I have a 123gig hdd, and after formatting, it shows up as 115gig.

    It`s to do with the way hard drives get measured. Take a look HERE.

    Regards Howard :)

    its a simple case of marketing..... 80 gigs in geek speak is ....

    1 bit = 8 bytes

    bit bit 0 or 1
    byte B 8 bits
    kibibit Kibit 1024 bits
    kilobit kbit 1000 bits
    kibibyte (binary) KiB 1024 bytes
    kilobyte (decimal) kB 1000 bytes
    megabit Mbit 1000 kilobits
    mebibyte (binary) MiB 1024 kibibytes
    megabyte (decimal) MB 1000 kilobytes
    gigabit Gbit 1000 megabits
    gibibyte (binary) GiB 1024 mebibytes
    gigabyte (decimal) GB 1000 megabytes

    in sales and marketing the gig has been rounded off to the thousandth, where as a true gig is 1.04 MB's. in a 80 gig drive, that is the number rounded off in thousands and not in geek speak. hope that helps a bit.

    business arithmetic: 1GB=1000MB
    Actual arithmetic: 1GB=1024MB
