Hello Everyone, I am an old Zidoo user, I started with Z1000, then Z1000 pro and just last week I got my new Z2000 Pro . I have updated the fw to newest one v1.0.75. Now when I connect my WD external HD 4 Tb my book (the big old one comes with Charger and USB ), as soon as zidoo begins to scan movies on HD then turns the zidoo off, I tried this many time and always the same. I am sure the problem not from my HD coz it works super on my PC and on my old z1000 pro works great . I tried to connect an smaller size and capacitate HDD Toshiba 500 GB and it works on Z2000 pro . Please Help me I had never like this issue in old devices of Zidoo
