I have a 2nd Gen Drobo (w/ Firewire). It has 3 drives (1.5TB, 1.5TB, 640GB). I added a 2TB drive (3 months old - previously only drive in a Mac Pro). Put it into the fourth bay and after a few minutes of nothing happening, the light then turns red. I have the lastest firmware and Drobo Dash. Anyone have any ideas what might be happening?
Please advise. Thanks.
