746 Gb=3TB disk

I just bought a ReadyNAS Ultra 6 plus, and 6 3TB Seagate Barracuda disks. I had the same problem. ReadyNAS identified each of them with just 746 GB. I did factory default reboots with all six drives in them, and with just one, and none worked. They kept coming up with just 746 GB per disk. Finally, I updated to the most recent firmware: RAIDiator 4.2.21 (http://www.readynas.com/?p=6469). I had to do this as a local update, because when I tried to do it as a remote one, it was also giving me trouble. So I downloaded the image from the link in the page I posted the url for here, and then used the local update option in the Frontview.

I then did the factory default reboot with just one disk, and set the volume to X-RAID when prompted by the setup software, and It identified the space in the disk as 2794 GB, which I'm assuming is the 3TB Seagate claims, and allocated 2790 GB to it. Now I've just added the second drive, with the machine still on, and is resyncing the volume in the background. It has also identified the second drive as 2794 GB, and I'm assuming it will allocate 2790 GB to it as well. I say I'm assuming bc this process takes like 3 hours, so it's still in the middle of it.

I did not have to remove any partition or do anything to the disks. I know some time has passed from the last post in this, but I hope that this info is still of use to anyone buying a new ReadyNAS.
