    Loss hard drive capacity


    Hi everyone.

    I'm using a notebook ASUS A43S that comes with HDD 640GB. I recently formatted my notebook and surprised that the hard drive capacity loss (40GB) and left only 596.07GB. I used EASEUS Partition Manager to navigate and divide the hard drive before formatting the notebook. What should I do?

    Nothing, it's standard, you lose quite a bit in formatting.... a 2TB drive formats to 1.8TB and change.

    It's a fun little game they have been playing for years.

    Really? That's weird, because usually it retains the volume capacity. Why it takes a quite amount of HDD after formatting? This is annoying

    Yep mate as Faladu says plus a lot of them come with their own add on software. Just done the same with a 320GB in asn old lappy and it was down to 298GB:)

    I meant to add ever noticed how many SSD's are 128GB??

    Formatting does have some overhead but that isn't the issue here.
    The issue is that most drive manufacturers define 1 GB as 1,000,000,000 bytes while in Windows it is 1024 x 1024 x 1024 or 1,073,741,824 bytes. divide 640,000,000,000 by 1,073,741,824 and you get very close to 596 GB.

    There is nothing wrong, no missing space.
