External HDD USB drive: A change in approach .
The LG oled Smart TV does not handle USB external drives very well. I often get false error messages. This is in part, I think, due to the fact I have often exceeded the 6TB limit on external USB drives. I have tentatively removed the drives and taken a different approach, for the time being. I have catalogs of the drives' contents that can be browsed and searched. I will use the catalogs to decide what I want to watch, then attach the drive(s) required for viewing. If I limit myself to the 6TB limit, there may not be any problems, but I suspect the Western Digital 4TB Passport is not completely compatible with LG software. The drive seems to work fine most of the time. I've not done exhaustive testing for a conclusive observation. One option not tested is the use of six 1TB drives, four on the TV and two on the router's USB drive inputs.
