RN422 reboot destroyed both my Discs

Hi,

replaced my RN104 with a RN422 - the 104 seemed to be very slow and was constantly rebooting randomly when ever more than one person was accessing it.

I used a 6tb WD Green HDD (from the 104) to Disc 1 position, formatted and restored the data from backup drives - ended up as Blue and Healthy on the Graphic. Was shown as JBOD and as Flex-Raid. Added one more 6tb the same as Disk1 to disk 2, Formated and made a global spare (Green Coloured on the graphic).

the Unit went to recovering and sync mode so i left it the 48 hours to sort itself out. I added a new USB Drive to backup data at a later date but that disc wasnt seen so after the Sync was completed and both Discs showing Blue i rebooted the unit so the new USB external drive could be seen.

There seemed to be no isue with the reboot at first but the USB Drive still couldnt be seen and Disc 1 was showing RED & Disc 2 Green on the Graphic. The only option for both was to DESTROY the volumes.

Any ideas what has gone wrong and what can i do about it ??

Looks like the options are to Format both disks and transfer all the data across again ?
