Lately, my G RAID mini using FireWire 800 can't keep connected to my Mac Pro 5,1. I don't know if the FireWire cable is now bad, or the FW port is bad on the G RAID, or the port is bad on my Mac Pro. I tried both FW ports that are in front of the Mac Pro. It will connect for a few seconds and then lose the connection. I'll get a "Did not eject properly" message. Any idea why this is happening?
