In a clean install of Win 10 from an upgrade from Win 7, File History was functioning on a 3rd internal drive I use for backups.
Because of a great deal of useless installation data being collected, I wanted to reset File History. Windows, from the Backup page of Settings, said I had to turn off the service first (do not remember specific wording as I was not troubleshooting then). I turned it off.
When I went back to turn it on again (without actually doing any editing to the file history file set), I attempted to Add a drive. Add a drive gives a "no usable drives found."
Using various diagnostic tests, including SFC and Troubleshooting from Control Panel, I found no problems with the system. I reformatted this 1TB drive (quick with default settings.
How can I convince Windows that this internal drive is good for File History?
Many thanks!
