Read some of the stuff here regarding wiping disks and securely deleting files. From what I've understood, after deleting (not securely) files they become part of the unallocated(free) space of the HDD. So if I want to securely delete the deleted files should I wipe the free space only or by keeping this link in mind What's a good secure file deleter take image of the C drive and then wipe the entire drive and finally restore the image??
