Recover erased NAS RAID

I am using Mac and WD PR4100 NAS. I seem to have completely wiped out my 2x8tb (RAID1) NAS. I may have deleted a file by accident and then began (what looked like a reformatting) of the drives. (I’m not even sure I did anything wrong) Anyway, I wasn’t aware of what was going on until it was over. Now I have 0 files left and none of my shares. The Recycle Bin is not there either. I can access the MyCloud screen but cannot connect to NAS with Finder.

Is there a chance I can recover my files?

Hi dr.mesmer,

Did you check your My Cloud data from

Yes I just did. Is there anything in particular I should be looking for in

Did you get any files stored on My Cloud when you signed in on
If not, then it is required to contact WD’s Technical Support about this.
