hi I can see my device (MyCloud3Tb) in windows file explorer but I can’t open it. I can click right and select “open” but nothing happens. I’ve tried restart an all te software from wd but nothing works. pleas help

sounds like the overall_share issue, if you are pretty comfortable with Linux you can manually fix it or you can do a system only restore, this leaves all data & shares in place and resets everything else like new
