As many of my peers out there I happen to be the “computer” guy in my family and friends circle, there are of course different levels of dependency among this crew but since I work, eat and breath computers they always assume I am up to date with the last piece of technology or the last software. Many a times I have been asked the same question; Why is it my newly installed Hard Drive of 250 Gb says it’s only 237 Gb? where did all my other Gigabytes go?. To my credit I have always explained something similar to the truth, but not quite. So it is my pleasure to find this explanation and pass it on, and by doing it I get the double benefit of setting a reference point for the future inquirers and a place of mine to send them to.
