After 6 hours of testing my patience (and the missus) i finally got my Q10 to accept my WD3TB, here is what i did (hope it can help others)
1: Connected my HDD to my Macbook pro and formatted the HDD to exFAT (GUID)
2: Turned on the Q10 after I inserted the HDD
3: Plugged in at 3.0 USB cable ind the Q10 and a normal USB in my Macbook, then the HDD got visible on my mac and then i formatted it again with the same format while connected to the Q10 (the HDD was inside the Q10)
4: After formatting I ejected the HDD on the MAC (not psychically) and then the HDD stopped spinning. Then I removed the USB cable from my Macbook and the HDD started spinning again inside the Q10 and it showed up in the media center. VOILA.
But it still leaves me with some problems and I hope someone can help me

1: It shows 2 discs in media center ( E(sda1) and F(sda2)) even though there is only 1 partition made when i Formatted the HDD
2: I can't transfer files wireless from my Macbook to the Q10, when i turned on Samba the shared folder automatically showed up un my finder menu, but when i transfer files to the sda1 or sda2 folder it tells me not enough disc space even though the it says 3 tb of space when I go into storage at the menu of the box. small files of 4 MB it transfers OK, but not big files.
There is no problem transferring via cable to the HDD and playing them, but I don't want to plug my cable in every time I want to transfer a file.
Hope there is help out there.
