      Eraser is an advanced security tool (for Windows), which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Works with Windows 95, 98, ME, NT, 2000, XP, Windows 2003 Server and DOS.
Eraser is Free software and its source code is released under GNU General Public License.
     Eraser 是一个Windows平台下的高级安全工具，它可以让你通过各种可选模式多次覆盖的方法彻底删除硬盘上的敏感数据。可运行在Win95/98/Me/NT/2000/XP/2003/DOS 等平台上。


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.


我实验用Eraser删除文件后，用FinalData2.0 无法恢复，连删除文件名都看不到。就是在删除的时候，有些目录会被申明为被占用而忽略，不知道为什么。比如windows目录。

当然,普通的删除，如果没有被覆盖，用FinalData可以恢复得很好。可惜是个商业软件。
