You can also zero-fill a drive on Linux, UNIX, or OS X by using the built-in 'dd' command. Assuming the drive you wanted to zero fill was designated as /dev/sdc:
Code:
dd if=/dev/zero of=/dev/sdc
dd is an extremely handy tool. You can even use it to make copies of CDs, DVDs, video games, even whole hard disks. Let's say we have a disc we want to copy in /dev/cdrom:
Code:
dd if=/dev/cdrom of=/home/donkey/MySweetDVD.iso
