Hi, I'm not sure how to explain it, but basically, many times when I'm transferring music onto my Sansa, out of no where, I'll notice that it just stops transferring, and I'll look at the player itself and it's completely "dead", and I have to unplug it from my PC and press the power button for a long time to get it to come back on, and then I have to reconnect and start the process all over. First I thought maybe the battery was low, but it does it regardless of how charged up it is--plus, it should be getting power just from being plugged into the PC anyway. Eventually I'm able to get everything transferred but it can't be normal for it to behave that way. Any ideas what the problem could be?
