I recall there was some software for overwriting blank disc space. I am
selling a computer and want to leave the OS on but make anything else on the
computer such as old SSN's, Credit Card info etc unrecoverable. Thanks in
advance.
Eraser can do that. Abandonware, but works fine.
"Eraser is an advanced security tool, which allows you to completely
remove sensitive data from your hard disk by overwriting it several
times with carefully selected patterns.
You can drag and drop files and folders to the on-demand eraser, use
the convenient Explorer shell extension or use the integrated
scheduler to program *overwriting of unused disk space* or, for
example, browser cache files to happen regularly, at night, during
your lunch break, at weekends or whenever you like.
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 the magnetic remnants from the
hard disk making it impossible to recover the data.
Other methods include the one defined in the National Industrial
Security Program Operating Manual of the US Department of Defense and
overwriting with pseudorandom data."
