I tried the 2*2TB solution with HD-WIU2, after upgrading firmware but didn't work. Got only 1.8 TB.
I am surpised since the previous upgrade fron 2*500 to 2*1TB was working fine.
I could get a 4TB RAID using MAC OS capability but it was not very stable.
Any other comment or help available?
2TB hardisk are Seagate, I am using Snow Leopard and connect HD-WIU2 with Firewire.
