PLEX data file storage locations

Make PLEX store all data for each individual drive on each said drive. That is all data for drive D is stored on drive D. All data for drive M is stored on drive M. This would enable you to remove HDD and plug it in to another machine running PLEX and have ALL the data for each file so there would be no need for the new comp to scan the new HDD. Also enable a way to lock any data for a file so it doesn’t get changed in future scans. I am tired of changing a date for a movie only to have it change or not show up after the next scan!
