Just bought one of these off the and installed 4 1TB WD drives. After going through the boot process, it seems that the unit is only using 2 (1 and 2) of the 4 drives. Drive status shows all four drives though, 3-4 are not functional. I don't know what I am doing wrong, can someone point me in the right direction?
1) make sure you update the firmware to the latest. They don't always ship that way
2) only use validated HDs
