I've been using a duo dock with my 2300 for several months, and it had been ticking loudly the whole time. However, I put up with it because I needed the dock to network the duo with my other computers. I"ve assumed that the ticking was the dreaded "tick of death," and my dock was living on borrowed time. Several days ago the ticking briefly accelerated and then completely stopped. Whenever I've used the dock since then I've had blessed silence. No problems networking with other computers either using a crossover cable or a hub with regular cables. What a relief. Is something terrible lurking around the corner or did I just luck out?
