My Bolt, model #TCD849500, worked perfectly until the hard drive crashed completely last night (those flashing lights look like the precursor to an explosion of some kind, attention received, thank you very much)... I replaced it with a 500GB Seagate I know works perfectly, but the lights on the front are still all flashing. My understanding is that the unit is supposed to automatically format a new drive when installed. I've checked, cleaned, and tested the connectors, the motherboard, and everything else I can think of. Since there is absolutely no satisfaction in throwing something out of the window when one lives on the first floor, can someone tell me what the problem might be?
