WD Word Edition II raid error

Hello all, i am using 2 WD Word Edition II NAS drives. Both with same disks.
One of NAS failed - on screen. So I cannot access files.
I can run web manager on it - but it is all.

I tried to swap internal drives to second one NAS, but no success.

Is possible to repair raid ? Is possible to get data from disks ?

Thanks for advice
