    You can use DBAN, ErACE, etc. They will over write whole hard drive. So it is impossible to recover data with any recovery tool

    Delete partition, recreate partition, reformat. That will deal with a lot of it, but 256bit or higher dod wiping is best for the paranoid, but really over the top for most uses.

    I have to agree with @n0tiert , disk destroyer (haha) is probably the best free tool to use imho, however I wouldn't use /dev/urandom or /dev/random as they add overhead, /dev/zero would probably be faster.
    Code:
    sudo time dd bs=1M if=/dev/zero of=/dev/sdx
