I just got one of these, but I have a question. I'm trying to get the external hdd from my old media player to work with the nvidia shield. however, it seems like I can't do anything unless I reformat the drive. is that the only way to get the drive to work? will formatting the drive make it usable in windows 10? it's already in ntfs format. it's okay if I have to format, since I made a backup, but I don't know if that's what you're supposed to do. it seems like a pita for large drives. btw, my drive is 2TBs.
