I am new to all of this and am running roon on a zen mini mk3 with a backup usb drive attached.
I have a small library 6k tracks, and noticed yesterday that about 1000 tracks, including whole albums were missing.
I was able to fix this by reinstalling from the back up on the innuous and then rescanning.
Today, I restarted the innuous and am missing the 1000 tracks again. I can’t seem to fix by reinstalling back up and then rescanning.
It’s the same tracks and albums that are shown as deleted by the way. Most were downloaded to the innuous but at least one deleted album was recently ripped.
