File/Directory Not Found, Device Not Ready

[rfajman]

I guess that I don't understand, or perhaps don't remember, while Retrospect can't find files, directories, and even whole devices even when it's running on the same PC that has the files, directories, or device it's trying to access.  And whether it's the client or server being backed up, nothing else seems to have any problem accessing the file, directory, or device.  It seems to me that Retrospect could at a minimum give error messages that contain some understandable explanation of the problem.  I'm currently using Retrospect 17.5 on Windows 10 Pro, but this has been happening for years, decades almost.
