See TrueCrypt, a free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux.

You can use Truecrypt in portable mode, Bitlocker to Go if you have a version of Windows 7 that supports configuring a drive with it or if you want hardware protection you can get something like an Ironkey

I didint know about the TrueCrypt or Bitlocker softwares, but i used to use WinRar and protect the rar file with a password... This dont disable the acess to files, but disable weird people to open your files..... You could use Winrar + Truecrypt for a high level of security.....
