Data Wiping Tools
If you need to remove sensitive data totally from your harddisk, simply deleting these files is not enough! Using advanced methods, it is even possible to recover data that's been overwritten, unless it has been overwritten using carefully selected platterns!
Operating systems usually do not totally delete the file, but just mark the file as being 'deleted' so it can not be accessed when you view the contents of a directory. This means that you can not see the file anymore with normal tools, but specialized recovery tools can still access your data.
To prevent this from happening, you need to totally erase your files, using one of the specialized data removal tools you can find in this section. These removal tools totally erase your data by replacing the contents of your files with effective data-patterns before deleting them the normal way.
