I got a new WD My Book 1130 3TB and connected it through USB 3.0 onboad Fresco port to my Asrock mainboard running Windows 7 64bit. When I use the Windows copy function I get CRC errors on every big file. This is a common problem, so I use TeraCopy and this works.
But after around 20 minutes my drive disconnects and connects one second later and the file transfer stops.
I have installed the latest drive firmware and mainboard drivers etc.
Anybody have a clue?
