    I have recently bought 160 GB seagate sata HDD. But after formatting it is showing only 149 GB, not 160 GB. Where has another 11 GB gone :-(

    No problem with his HDD dude.....

    Hard disk companys don't see things in quite the way u do.1KB is considered equal to 1000 bytes.The actual number is 1024(which is raised to the power of 10).Now consider your 160 GB hdd is equivalent to 160,000,000,000 bytes according to the hard drive.The OS calculates the capacity using 1024 (correct binary calculation).Therefore, if u thke 160,000,000,000 bytes and divide that by 1024, the answeris 156250000KB.Divide by 1024 again to get 152587.890625MB.Divide this by 1024 and u get 149.0116GB..Its just that the hard drive companys round off 1024 to 1000 (which is not an accurate way of displaying the capacity of the drive)
    SO stay calm and no need to panic........

    160GB real = 160 X 1024 MB

    160GB of company = 160 X 1000 MB = 160 X 1000 / 1024 GB = approx 156 GB

    anyway even mine is around 148 GB

    The "scraping off" starts at the very low levels i.e. from Bytes to KiloBytes.
    so, 160GB is therotically 1024x1024x1024x160 Bytes
    whereas it is 1000x1000x1000x160 Bytes

    so the actual space that you get is ( Cx1000x1000x1000 )/ (1024x1024x1024)
    where C is the theoritical capacity (160 GB in your case)

    so in your case it comes out to be 149.0116119384765625 GB
    in case of 80 GB it comes out to be 74.50580596923828125

    @cooldude: No, the loss in case of RAM is due to sharing for graphics. If it were the other way, it would have been 244.140625

    Hope this helped

    EDIT: sorry I didn't read wizrules explanation
