Jay has a Mac Mini and wants to know if he can run an app that can "break" his hard drive. Leo says that's an interesting thought. There isn't really a way to do this other than just by exercising the hard drive more. There's MacDrive Testing software that can do it. MicroMat makes an app called Tech Tool Pro.
But why not just buy a new hard drive? It's not hard to replace. He'd just need a putty knife to open it up. Let the hard drive fail and then replace it. Another option is that the hardware manufacturer has software that can diagnose it, and he could use SpinRite.
