I am trying to get a 321 working with 2 1.5TB seagate drives in RAID 1 mode. I have upgraded the 321 firmware to 1.01. After doing everything, I can only map the network drive on 1 computer. When I attempt to map the network drive on another computer, I consistently get "Failed to map drive" error. I have tried several permutations of users/volumes and I am still getting the same problem
