best software to clean hard drive
By looking at your avatar I can only suggest that you ask them. If you really need to wipe your HDD I normally use Ubuntu and right click the drive I need wiping and format it. Its good enough for me.
If you really want to wipe it that bad just buy a new one and burn it… Should not be doing anything malicious anyways.

None of which are SOFTWARE :angry:
Anyways, IMO your best bet is to run a dd on your hard drive. The command to run a full zero drive is "dd if=/dev/zero of=/dev/sda bs=1M" http://en.wikipedia.org/wiki/Dd_%28Unix%29
