Please tell me of the best thing to do to delete a data from my hard disk so that no one would ever be able to retrieve it. I would highly appreciate a way whereby which NO ONE can retrieve it but I STILL CAN. Well, if I can’t, no problem. I just want NO ONE ELSE to retrieve the deleted data.
Secondly, please tell me of the best way to recover deleted data that has not been deleted by means of deleting it for FOREVER, as I’ve asked above.
Urgent help required!

To securely destroy data you need to do more than format. DBAN will nuke a whole drive, Eraser 5.3 can wipe specific files or free space. Those are unrecoverable except for a handful of world-class experts. The only sure way is to physically destroy the drive. If you securely wipe some files but not the whole drive, there are other things you need to be aware of — temp files, swap space, etc.

For protecting your data, try strong encryption with PGPi. It uses asychronous key encryption. This application also has a shredder utility that can delete data on the disk by overwriting the sectors multiple times with random data.

Overwrite entire hard drive
Use one of the following methods. These will overwrite all data on the hard drive.
DOD 522.220-M requires 3 overwrite passes

Shredding and system restore will not work. And you should not sell the computer until you have performed a "secure delete" of the hard drive contents and free space. A secure delete encrypts all the information on magnetic media, thats your hard drive. Then deletes the information making it unreadable. It does this several times to make to make the information unreadable.
A secure delete is the on form of data removal endorsed by the US Department of Defense. I do work for a patent company we use Evidence Eraser. It cost about 25 dollars. There are only about six programs on the market that have past the US. department of disk santization. Its one of them. Here is a link for more info

You require following two software to effectively do your job.
For Data Wiping & Erasure, you require Data Wipe from http://www.recoveryourdata.com
And to recover deleted files you require most powerful data recovery software i.e. Recover Data for FAT and NTFS by Recover Data Labs. Get the software from http://www.recoverdatatools.com or http://www.recoverdatasoftware.com
