Full reinstall of WD software?

No real answer from Dell after several days, I’m resigning from using the unit and will return it. Anyway, I’ve understood that a NAS RAID is for acting as sever, and that its usage as shared storage is dangerous because deletion errors are instantly mirrored. Since my iMac is always on and uses Time Machine, its preferrable to directly connect instead an external disk and serve part of it from the iMac itself. Cheers - José
