Good evening, ZIDOO Z9S has finally arrived and I have provided to adjourn it to the last firmware 2.1.30. However in connecting my 5 hdds from 4tb from USB I have a problem. The first two hdd are recognized with the same files, so the same files of the first hdd are also in the second hdd. But if I turn off the mediaplayer and I restart it, there is the same problem but the files of the first hdd are the same of the second hdd, so with a reverse result. I can not understand where is the problem. I premise that with the mediaplayer himedia q5 4k I didn't have this problem. Who can help me? An anticipated thanks.
