Research and experiments

Beyond simply describing the tools and methods, I wanted to perform experiments where possible to learn how difficult (or easy) they are to employ. The details given are my own experience (unless otherwise cited). For these experiments, only open-source and free software was used to show that the tools needed to hide information are available to everyone. The Windows-based experiments (for FAT and NTFS) were carried out on a Windows 7 virtual machine running under Oracle VirtualBox 4.0.6 for Linux. The Ext and HFS experiments were done under Ubuntu 10.04, which has a grand ability to handle non-Linux file systems.
