Asus P8z68-V/GEN3 board. Installed 2 new 4tb drives, went into the raid setup and it sees both drives as 3.8 something and added them to the array, start windows went into disc management and it shows drives but as 2 2tb drives. Whats the deal here? Is this actually the 4TB drive showing up as 2 2TB drives? Now this shows as 2 2TB not one full drive partitioned into 2 2TB. The raid array is set to mirror.
