That is my fear with carbon forks. I hear too much about them disintegrating. Yeah, a good carbon fork is supposed to feel like steel. The benefit is the weight reduction. If I want to feel like steel, I'll ride on steel. Weight doesn't matter that much to me. After all, I weigh a whole lot more than the bike anyway.
Like Mr. Bontrager (can't remember his first name, sorry) says: "Cheap, strong, or light. You can have 2, but not all 3."
I'm more comfortable physically and mentally with a steel fork. (which my Kona has, and my Waterford has.)
My biking gurus at my LBS say steel can break, but it generally fails slowly enough that you can tell something is wrong and stop while aluminum and CF do "catastrophic failure". (these guys are crazy mountain bikers and really trash their bikes, your results may vary...)
