As i've been using it i've noticed my ipod has been working fine for the longest time, but reciently there are 2 things I notice that happen occasionally. 1. Once in a while when I plug an ipod into the comptuer it freezes, though this hasn't happened in about a month now. 2. Sometimes I hear clicking sounds like what you hear a lot on like older mac laptops that usually occurs when the mac has to process a lot (kind of?)anyways reciently I hear that on my ipod but it hasn't before. So I just wanted to know is there anything I should worry about that could happen in the future or will it likely work just fine?
