Yeah I think I will try to do that also. From all the answers in this thread, I came to a conclusion that I can will give time to use this applications for shredding, wiping, dban, and erasers, after doing that I will try and restore the disk, once I find out which one has done a much better job. That is what I am gonna post here so that many people can benefit from it. Thanks everyone!
Yeah that maybe one of the possible things to do, but I will need to buy a new hard disk and that's something I can't afford to do. But thank you very much for the link you have send I will try to read that so I can learn from it.
@valentino, I know how to back up or transfer all my file from a laptop to another laptop or to an external hard drive or in any other storage. What I am asking is how to totally wipe out a drive so that all the information from it that was erased or removed will not be restored by anyone. I don't need to go to a computer shop or trouble shooter because I do that, that is my forte, I myself restore data from corrupted hard drives by my costumers computers who they brought to me for fixing. That's why I know data can be restored, what I don't know is how to wiped everything out so no restoration can be done to the disc.
@Martinsx Maybe also look at this Video Editor you have bumped too, I am also sorry if I have not replied right away from all of your inputs on my question, I got in a household problem that I really need to fix. Though it is not yet fixed yet, I just need a couple of breather time that is why I went back to posting. Thanks to all!
