At Storage -> File systems, when i press on hdd in question. Unmount button is still grey.
And on the right side there is still sign to be refferenced.
At
Storage -> Shared Folders Delete Bin is also gray color.
Prior to this i have deleted shares for smb.
First disenabled(pen icon) and than Delete/Bin icon.
I supose, bin icon was my error.
Is there a way out of this mess?
