I am going to send back a laptop that’s under warranty and I want to make sure all my private information is removed. How can I delete the hard drive with all my stuff on it. Anyway to do that?
If you have a copy of your Windows install/recovery disc you could use that to format the drive and reinstall Windows. By formatting the drive you are basically deleting everything on that hard drive and starting over.
If you do not have a copy of your Windows disc than you could use Darik’s Boot and Nuke to clean your hard drive. DBAN if free to download and use, you could put this program on a cd/dvd or usb drive.
