First of all thanks to @crieke for his work on this. I have been able to get Roon working using a USB connected SSD drive and it runs really well.
I would like to use eSATA instead but I can’t get this to work. I’ve tried 2 different eSata cables/enclosures and followed the instructions I’ve found.
This screenshot shows I changed the description to RoonServer but roon throws an error whenever I run it and then works again if I go back to USB. The screenshot shows an old roonserver I setup internally 1st.
