Version 1.21.1.3842
I got a new external HDD and copied all library contents across as per the articles.
No issues with 2 of my 3 folders, Movies & TV Shows worked without issue
Having confirmed that all the data was successfully copied across to the new disk I formatted the old one, and did a library scan, the old data still remained,
I also tried copying in one album folder to the old location, still not working.
I can delete each album individually without issue, but how to I get rid of the albums that are now orphaned?
You cannot remove the last storage location of a library. Add the new location first, then remove the old.
Sometimes it helps to reload the web app in your browser (F5) before editing libraries.
Never point Plex to the root of a drive. Always use subfolders.
You don’t appear to have Artist folders in your music storage. This won’t work for long.
Always use this folder hierarchy: Music -> Artist -> Album -> tracks
That’s the new one, with all the artist folders in the Music directory,
The D:\ was the old formatted location, that I could not remove after adding H:\Music
So I copied one folder back in to the previously empty D:\ and did a scan again, thinking that would remove the old references to anything in that location, but no cigar
Or inspect them yourself. Take a look at the Plex Media Server.log file and seek for messages about database corrupt or malformed.
If you find these, you may have to repair your database.
