Does drive wiper wipe the hpa and dco areas on the disk? If not is there any app that does?
Deleting or wiping a hidden factory partition is one thing. But do you really want to be messing around with the drive configuration overlay? Doing so could turn your drive into a very expensive paperweight.

"Yep, and anything messing with firmware that is not explicitly understood can result and in some cases will result in an aluminum brick with round discoid shiny things and a very powerful magnet inside." – Fiasco Labs
Nevermind, did some more searching and it appears drive wiper does not wipe those areas of the disk, but I found a couple of other apps that do.
All right Stonefish, I'll give you the answer to half of what you seek to do. But first, I want you to go back and reread the link I posted last night. Because what they are talking about is using the Linux command hdparm to reconstruct the DCO. Doing so is not without risk. Get it wrong and you brick the drive. What you are talking about is wiping the DCO. Unless the software utility you plan to use is 100% guaranteed utterly reliable, it sounds to me like you have a very good chance of turning your drive into a paperweight.
Edited by Derek: I removed the rest of this post. I gave advice that if misunderstood or misused could have had serious consequences. I apologize for that. I'll only say that factory installed partitions and the drive configuration overlay are things best left alone.
