Mycloud share folder disappeared

After completing a firmware upgrade (v04.04.05-101) of my mycloud, I’ve noticed that my share folder is missing? I had only 800Gb storage remaining and now I have 2.7tb so I’ve lost 1.7Tb of data??? I’ve no backup as I’ve only just copied the files across in the last few days

I’m running windows 10, I’ve no problem networking and seeing other files under other share folders except one.

How can I restore the share folder? or recover the data

I have not written anything to the mycloud since

Try performing a System Only reset on the device from the dashboard.
