Hi

Sometimes the unit will reboot once in a while & sometimes it will do it 2 or 3 times in the same day then it will continue to work fine for awhile does that mean the SD card is going bad? and how can i copy the files over to a new one? before it stops working completely. would it be as easy as taking out the old one and putting it in a PC copying the files or is there more to it then that?

Let me know thanks
