Re-copying data and want to re-write parity in General Support Posted February 19, 2020 I went to MicroCenter and bought a new USB3 external hard drive dock. I figured I'd be wasting my money so I unpackaged it very carefully. Not ONE problem copying files back ever since. There's no reason why two older docks shouldn't work and this one does. I can only imagine, somehow, there's a limiter on the size of the hard drive or on the NAS end of it. We're talking only 6TB. AND the really sad thing was, all because a couple of movies weren't playing correctly. KODI playback configuration needed a change and everything plays as it should. I went completely stupid TWICE.
