I have loaded music on to the sansa device over the years from different computers. Now when I plug the device into my laptop it detects the device but it can see no music in any folder. Folders are there but empty. Music is in the device, i can listen to it fine with headphones and it desplays fine in the sansa screen on the device. But it shows no music on the laptop. I have the latest firmware and I have tried the msc v mtp thing and nothing either way. Any more ideas?
