A word of warning. High capacity external drives require quite a bit of juice to run them and you could end up damaging the tablet. I have had a 1.5tb NTFS formated drive running on this. Haven't tried FAT32 formatted large capacity drives but USB sticks have worked great. You either don't have enough power to run the drive or its not formated correctly. The files should appear in the file explorer app under the USB1 icon or within whatever video or audio apps you have installed.
