Thank you for the prompt response. I do not get error messages. The drive is recognized in windows explorer. The grey add button will not let me add ANY watch locations - on the computer drive or external drive.
I also just noted could not edit the schedule backup fields. It seems an interface problem with the settings screen.
I m rubbing new Dell XPS 15 laptop with Roon on it. I have a 500 GB external laptop drive in a case connected by USB to a “Pluggable 3.0” brand USB HUB, which is concocted to one of the computer USB jacks, which works fine.
Thanks, Bill [Personal information removed by support]
