[Help] WD My Cloud Expert EX2 Ultra [Disk Recovery]

I have a WD My Cloud Expert EX2 Ultra and had Raid10 installed
I formatted it by mistake, if there is a chance to recover the files and what is the best way to fix it? Thanks in advance
Note: Since then one drive is completely intact (drive 6 wd Green)

How you get RAID10 on 2 disks?

You can try recover data via direct plug HDD to PC

yes! 2 disk
Will any important software be required?
Or will it directly see the formatted disk?

You need software like -R-Studio

Is there a free solution? At home?
