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.
When you delete a file, the operating system does not really remove the
file from the disk; it only removes the reference of the file from the
file system table. The file remains on the disk until another file is
created over it, and even after that, it might be possible to recover
data by studying the magnetic fields on the disk platter surface.
There are several problems in secure file removal, mostly caused by the
use of write cache, construction of the hard disk and the use of data
encoding. These problems have been taken into consideration when Eraser
was designed, and because of this intuitive design and a simple user
interface, you can safely and easily erase private data from your hard
drive.
