I‘m going to upgrade my FreeBSD 7.x server hard disks and going to send back the original 73GB hard disk to my vendor. I wanted to make sure that no one should able to use my personal data from old hard disk, especially files stored in /home/you/projects directory. I know how to use sDelete under MS-Windows to delete a file permanently. How do I permanently erase files under FreeBSD operating systems?
