hard drive - Program to wipe HD?




What is a freeware app i can use to wipe a HD?
I have two


1) My external which is <1yr old and is reported 'failure' on disk health checks (maybe i wont bother wiping this?)


2) My laptop which i may send in for repairs or get it replace. It currently is under warranty.
