Restoring the Full Capacity of an SD Card

During my projects with single board computers with embedded Linux like the Raspberry Pi, the Beaglebone Black, pcDuino or the Cubieboard, often happens when I need to use and reuse SD cards to install Operating Systems into the boards. However, if later you want to use that same card as a normal storage unit, you might be surprised when you find out that a few MB or even GB are missing and worst, a simple formatting just won't fix the problem.

This happens because the card was formatted to be used with a Linux partition and Windows simply doesn't know how to deal with that. Fortunately there's a tool for that.
