Hello. Hi. My Big Disc Quadra 2T drive is not recognized by my mac. It had happened a couple of times before but plugging in and out seemed to fix the problem. I tried all your solutions. I was connecting it via Firewire800 with my mac. The drive powers on but is not recognized. Any idea what to do? I've emailed them but in France. I tried contacting them through a web form but the only country i could choose was US which is lame cause i live in Greece. Any ideas on what to do? Should i open the case to get the two drives out? But then will i loose the data because of the raid configuration (sorry, i'm not into technical stuff).
