I have had problems for a long time w/ getting it to a. transfer files w/o the sd card being write protected. b. 50% of the time or more it will only play for about 5 seconds with a new battery and then turn off c. I did drop it in some water once and tried to dry it, but I guess it messed up the hard drive. It was after that, the SD card was working part of the time. I have checked and it's not locked or anything. HELP PLEASE!!!1
