Hi guys, I'm typing this (really slowly) from my iPod, because I can't get on my MBP right now, so if you have any advice at all, please lay it down. I upgraded to snow leopard when it was released. I was already getting the occasional question mark, but after the upgrade things got worse. I was told at beat buy that my HD was shot. One week later, I had a new HD....and a month later, more freezes and question mark folders. I read online that I should do a clean install...do I did that. About two weeks later, the question mark folder was back, and worse than ever. I don't know what to do. My HD is practically new, it can't be failing already, right? I'm at a loss for words, and I'm frustrated beyond belief. Help!
