What does “wiped clean” actually mean? Did that family relative do a “Full Restore” from the My Cloud Dashboard to wipe the device contents and set the device to factory defaults? Or did they physically pull out the hard drive and wipe the drive via their computer and then put that drive back into the My Cloud enclosure?
If they did the latter then you may have to use one of the various “unbrick” methods that can be found via a search of this subforum to configure the drive for use within the My Cloud enclosure. The following link is one such general guide for “unbricking” a WD My Cloud hard drive.
