As to why you are having books disappear, you might want to check in the calibre forum. That was a known issue where file/directory locking prevented calibre from removing a book when, for instance, the author name was changed. A search for 'file locking' in the calibre forum will come up with more information. A couple of threads that might be helpful are Calibre deleting files after edit metadata and Books missing from library but showing metadata?. |
