The rotors I have are the ones that came stock on my Rockhopper. The front is just barely warped and I was able to adjust the caliper so that it doesn't rub at all. The back, not so much. I've tried adjusting the caliper but it is still rubbing just enough to annoy the crap outta me. I haven't had any impacts on the rotors so I don't think that'd be an issue. Could improper bolt tightening sequence warp the rotors? They've rubbed since day one.

Those Hope rotors are fantastic but, I don't think they work with my calipers
