Hi I have just got a new OLED B7 TV and would like to know if I can use my old USB HD that I was using with my old LED LG TV that was using the LG time machine 2. When I plug the USB HD into the new B7 TV it says I need to format it. I see the new TV's need a NTFS drive and on the old LED TV it was using a linux system. Is all lost are any way to view the old data on the new OLED TV ? Thanks Paul
