Readynas duo larger hdds

I just recently bought a readynas duo as i alread6 have a readynas ultra home.
This one has 2 hdd slots.
I have all my nas set up as 0 in raid as i need most storage and arent really worried about loosing any storaged files.
This unit came with 2x 750gb hdds and i took them out and stuck in 1x 3000gb hdd and 1x 4000gb hdd. But one drive only show 1600gb and the other 750gb.
It doesn't make any sense. I have used both of these hdd in my ultra and i have tried resetting everything 4 times already. Tried hotswapping and disk quota and files check etc.
But it seems i cannot find out what the f. This problem is.
Yeah i know its a old unit, but its upgraded with 1000mb ram and surely it should be able to read a simple harddrive and get the storage available correct??
Thank you for all suggestions.

    The other labels can be confusing - that's why I posted the way to distinguish the models.  What you have is hardware revision 2 of a Duo v1 NAS.

    The chipset / hardware architecture goes back to ~2005.  There isn't any way around the 2 TB limitation (firmware, software, what have you).  You'll also find it can't access USB drives that are bigger than 2 TB.  

     

    So you are limited to 2 TB of RAID-2 or 4 TB total of jbod or RAID-0 (2x2TB drives).

    I think you purchased a used Duo v1.  That would

    • say Duo on the front chassis
    • run 4.1.x firmware

    A Duo v2 would

    1. say Duo v2 on the front chassis
    2. run 5.3.x firmware

    The Duo v1 is an old design that was discontinued in 2011.  It never supported GPT formatted drives - so the max size you can use is 2 TB.  This has nothing to do with the amount of memory, and there is no way to fix it.

     

    So you'll either need to use 2 TB drives or you'll need to return the NAS to the seller.

      but there doesnt say V2 on the front.

      I cant return it to sender as i bought it used obviolsy and he sent it to me so to send it back it will have costed me more than the NAS itself. So ill guess if i cant update it in any way i just resell it to someone else just as stupid and unlucky as my self.

       

      But is there no unofficial software or firmware anywhere?
