I have had problems putting files of a curtain size and over onto my seagate hard drive, I then got told i needed to reboot it, which I did and now the files go on there with no problems. However, I have now gone and plugged it into my TV and the device shows up but no files on the device…. I have checked that the files are on there which they are. HELP! I have no idea why it won't work and seem to be a novis with this stuff. I have a seagate go flex is that is any help
