I am trying to load music onto my S3 and am having an issue, When I plug it it it shows up on my computer, I navigate to the Music Folder and try to Drag and drop the files into the folder, The Screen on the S3 shows synchronizing.. and on the computer it says Copying but then a message comes up that says The device has stopped working or has been disconnected Stop Copying or Skip file.. I have tried both options and still can not get any new songs onto the S3.. any ideas
