    the nas sees the 80gb, its recognized when i hit the disk icon but also says corrupt root , the nas also sees both hard drives and displays them also when i hit the disk icons but stills says corrupt root. 


    Did you try doing a factory reset using the boot menu?  This is done with the disks installed:

    1. Power off your system.
    2. Using a straightened paper clip, press and hold the Reset button.
    3. Press and release the Power button to power on the system.
    4. To perform a factory reset, continue to hold the Reset button until all Disk LEDs flash twice (once at 5 seconds and then 25 seconds later), and then release the button.

    Make sure you hold the reset button down long enough on step 4.

     

    The reset button is recessed and is on the rear panel:

  • What does RAIDar say with no drives installed?  If it simply says "No drives", then that message likely being caused by drives that were formatted outside the NAS and a factory default is the solution.  See How-do-I-access-the-boot-menu-on-my-ReadyNAS-Duo-NV-NV-X6-or-600.   If it's something else, you'll likely need a USB restore.

     

    4.1.8 is very old (not that the most recent 4.1.16 is that new), but I recommend you try to get it going with what's already on there before you update the OS.

        What happens if you power down the NAS, put the 80 GB drive back in, and then power up?

    FWIW, you actually have the original Duo (called a v1 here).  The labeling is quite confusing.

     

    The system boots from the disks, and the corrupt root means that there is something wrong with the OS on the disks.

     

    As Sandshark says, the usual solution is to do a factory default.  Instructions are on pages 15-16 here:

     

    I imagine the disks are old, and might not be healthy.  You might want to replace them - Seagate Ironwolf drives would be a good choice (don't use desktop drives).  Either 1 TB or 2 TB will work - your NAS can't handle anything bigger.

        Nobody said there is anything wrong with the drives.  The drives must be formatted by the NAS itself, and the message you are getting is usually because there is some "foreign" partitioning/formatting on the drives.  That you tested the drives with a partitioning tool makes me think that even more.  Use that tool to remove all partitions, then return them to the NAS.
