Probably just as interesting as TrueCrypt, but more useful, is Eraser
, at least for Vista. This utility is also pretty slack when it comes to Human Interface Guidelines, but once you get into it, you can't beat the functionality: Securely delete files, folders, entire volumes, free space on volumes (including cluster tips), the recycle bin, etc. All just a right-click away in the Explorer.
Eraser implements Peter Gutmann's 35-pass file wipe
(and several other algorithms, some of them explained a bit in the docs.) Gutmann is the default mode for Apple Macintosh's secure file deletion, source available either from Apple, or from srm.sf.net
