We upgraded our external HD recently from an old 64gb Passport to a 4tb SeaGate. We would use our passport on the TV without a problem. I simply copied all of our information onto the new HD, and plugged it into the TV, but now it only shows an empty folder called "LG Smart TV", which isn't even on the HD. The HD was formatted on a mac, but the old one was as well. All the files show up on the computer when it is plugged in there. Does anyone know why this would happen and how to fix it?
