Eraser is an advanced security utility, which enables you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns.

Eraser is FREE software and its source code is released under GNU General Public License.

The patterns used for overwriting are based on Peter Gutmann’s paper “Secure Deletion of Data from Magnetic and Solid-State Memory” and they are selected to effectively remove magnetic remnants from the hard drive.

Other methods include the one defined in the National Industrial Security Program Operating Manual of the US Department of Defence and overwriting with pseudorandom data. You can also define your own overwriting methods.
