Darik's Boot and Nuke (';DBAN';) is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.





DBAN is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a good way to totally clean a Microsoft Windows installation of viruses and spyware. DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.





The development and support of the DBAN software project is funded in part by GEEP International. GEEP is the largest, the most efficient, and the most environmentally conscientious consumer electronics recycling company in North America.
Short of re-installing XP you can't but that's not a foolproof method either I would say. Someone with enough knowledge still could pull stuff off your computer.





Probably your best bet is to nuke the drive using this program that I found at Lifehacker http://lifehacker.com/5090567/dariks-boo鈥?/a> and then re-install XP if you want to give it away with an operating system.





Hope that helps!
you need to use a back up storage drive / media (flash drive / dvd or cd data burning as backup file / external hard drive or use a multiple hard drive *drive c: and drive d:)


step 1: transfer all the files to the backup storage drive


step 2: format the drive that is needed to be formatted


step 3: transfer back the file being transferred earlier.

you need to reformat your hard drive, that way it will be mostly clear.
do a system restore to the earliest possible date
reinstall xp
