No need for that, I think it would make things inconvenient... especially if it's your root filesystem! Don't confuse spindown with parking of the heads. Spindown is just normal power-saving and happens all the time if you own a laptop or any modern consumer-grade hard drive... some of them don't even allow you to disable it anymore!
