Has anyone had an issue setting up a Buffalo 2TB (2x1TB) Drivestation duo on their MAC? I'm trying to figure out if the bus is bad, or the enclosure is bad. I don't thinks it'a drive, both drive lights are green. I recently bought one and want it to work with TM as a raid1. When its connected, only 1 drive shows in disk utility. It doesn't matter if its connect to a USB hub 3.0 (hoo too w/power supply) or into a 3.0 port on the iMac. Im current on all updates, running 10.9.1, iMac 21 late 2013. Buffalo instructions are non existed for Apple (step by step though if your Wintel).
