Careful before formatting, as this erases all media from the device. By stating “I have nothing on my player”, do you mean that you cannot see any music files when looking from teh PC, or that the player is actualy “empty”, meaning that there are no songs available when using the device?
The Clip+ can connect in one of two USB modes, MSC or MTP. When you are connected in a different mode from the one used for music transfer, the files are not visible from the PC side, though the Sansa will display all files.
