Well, I am about to run KillDisk - so wish me luck. Hopefully all will go well, if not, oh well. No SHO for me.
Kill disk is a great utility, especially if you want to start your harddrive from scratch. It writes over every block with a 0, then a 1. Then there's nothing left.
you can find it here, if you are gonna do the same thing:
