Secure hard drive files erasure
To securely erase hard drive files is not just simply press the delete button on the keyboard, but to overwrite the hard drive with pointless numbers so traces of deleted files can be replaced.
Why a deleted file can be revered before new files come in? That's because Windows file deletion only removes the pointers or references of a file, not the actual contents of it, when data recovery program scans each sector on the hard drive, all the contents or the leftovers of original files are there to be recovered.
