Hi, I have a 43uj635v running webos3.5, and a few external hard drives. I only got it 2 days ago. My 2tb Seagate expansion works with the TV, and also a 1tb works, but I try and use my Seagate 2tb back up plus slim, and it doesn't find it. Sometimes it says unknown usb device connected, and sometimes it says please reconnect after disconnecting, and that pops up quite a few times, until you remove it. I just don't get why one 2tb drive works, but another, newer one doesn't. But they both work perfectly with my old LG tv, and with PC's and my xbox
