Eraser Portable 5.8.8
securely erase your data
Eraser Portable is a secure data removal tool that runs directly from your iPod, USB thumbdrive, portable hard drive or any other portable media. You can plug it right into any Windows computer and use it just like you would on your own. It is a repackaged version of the popular Eraser utility designed with portability in mind, so it has all the same great features of Eraser, but there’s nothing to install.
