    I have had this problem for a while, and finally after a while of not being able to figure out what's happening, decided to ask for some help.

    I don't know how, when, but quite often, if not always, Windows (XP SP2) shows incorrect numbers for free disk space.

    For example,
    for disk C: it shows
    Used Space: 17GB
    Free Space: 76MB
    Disk capacity: 20GB

    As you can see, 3GB are missing.

    What's strange, is the following. Anytime I see this, I make a copy of a file big enough that makes the size of the free space much lower (say 15MB). When I do that, instead somehow the missing space "gets found".

    Why is this happening?
    What's causing it?
    How can I get rid of it?
