ReadyNAS Duo issues

Basic info:

Windows 10 1803, Raidar Version 4.3.8, ReadyNAS Duo RND2000v2

I have a readyNAS Duov2 device. It's been in storage quite a while but I thought I's get it out and see if it will work.

I have two 2TB disk, each of which are fully working. I am running RAIDar 4.3.8 (I read it's the only one that supports RAID 0)

When I boot it up, the program finds the two disks, but it says corrupt image. I did some searching and most posts said to do a factory reset, which I did, powered off, held the reset button, powered on, waited for 5 seconds. Got into the program, same thing. All the while, my ReadyNAS leds are flashing, 3 long flashes followed by 3 quick ones. This time the reading says to go into the boot menu and do a reset.

So I turn it all off, hold the reset button and wait for all the LEDs to flash. Except they don't all flash, the blue power light is constantly flashing and the two disk lights flash once every 20 seconds or so.

When I do release the reset switch, I get the power light flashing and a solid green light on disk 2, which supposedly means memory check. OK, I leave it to run for an hour. Then reboot. I still have the corrupt boot on the RAIDar program.

Can anyone advise? Am i wasting my time trying to get this to work?

Thanks

David
