ROCK keeps deleting all music in local storage

[BlackJack]

From Roon OS Data Directory:

Note: You cannot store music on the Roon OS system drive.

If your Roon OS device has internal storage or a connected USB drive, you should see a folder in the /Storage directory:

If your /Storage directory is empty, your Roon OS device does not have media storage available. If you think something might be wrong, let us know.
