There is an issue with steganos drives encrypted. Not showing after mounting, this happens only in few last updates of opus. and only after waking up after sleep. explorer shows all drives correctly, opus - no.
no opus elevated.
The drive icon appears in the toolbar at the end. Is it appearing after a delay or did you do something (e.g. a hotkey) to trigger that?
Does it appear in the This PC folder if you refresh it with F5?
On the toolbars, what are the Drive Button command(s) there? I suspect there are different commands showing the C and E drives compared to any others, as the icon sizes are different.
One has large images and the other small, which explains the icon differences.
Does taking out the ,hideempty make a difference to when the drive appears on the toolbar?
nope. all the same
i can even navigate in FileExplorer to this disk, create folders and files - no changes in Dopus (Toolbar and This PC)
dismount also does not change visibility, it stays visible until manually updated This PC
It's possible the drive-change notifications are either being blocked by something or aren't being generated properly (e.g. generated before the drive really exists, or not specifying the right device).
(The toolbars will notice when updating for other reasons, but This PC won't refresh unless an event from Windows tells it to do so.)
now, after few goings to sleep and awakenings, appearing of this drive has returned to normal, without any restart.
