I just lost the entire contents of my external hard drive. It was just my Time Machine backups and about 90% of my Plex media. Fortunately, I have a list of all the things I need to re-download, but my Plex still shows the lost items as being part of the library. I tried to force refresh each library as described here: https://support.plex.tv/hc/en-us/articles/200289306-Update-or-Refresh-a-Library but the deleted items are still showing in library!
I will eventually re-download everything, but in the meantime, I do NOT want to see the stuff that I can't play! How can force Plex to basically rebuild its database from scratch, since a force refresh isn't doing what I need?
