My Metadata file seems corrupt

gandor62 · 03-13-2010, 10:41 PM

I had trouble after I reinstalled my Vista Operating system and when I reinstalled Calibre and used a backup of the folder with all my Ebooks, it seemed to have lost a lot of data. I renamed the Metadata database file and reloaded all the Ebooks from the Backup folder to try to rebuild from scratch. All the Books seems to come in OK but on a better inspection a lot of the covers are wrong. When I view the book in the inbuilt reader the correct cover shows up ok, but in the main window or cover viewer that shows all my books, the incorrect cover is shown. But not all are incorrect.

Is there a way to rebuild the metadata file index or some other solution.

I still have the original folder backed up with the original metadata file intact.

One thing I did try was to edit metadata for a book and re download a cover, which went OK and showed the correct cover in the title viewer. But when I went back to it after editing a few more titles the cover had gone incorrect again.

I thought it may have been due to modifying my entire Mobipocket collection to enable me to read on my kindle and iPhone using a plugin, but when I inspected non DRM titles they had the same problem.

Any clues anyone. I cant start from scratch as there are over a thousand titles and so much time invested in doing the library.

Thanks in advance

Ok solved the problem in a way.

I deleted everything. Uninstalled Calibre, then reinstalled Calibre and added books from backup directory to a new folder. Seems to be all ok now.

That didn't repair the database file. It just replaced the corrupted one with a backup. I would like an answer to the original question on how to rebuild a database file.

Preferences > Advanced > Check database integrity. That checks the database and fixes any errors.

However, if your database is badly damaged, you can lose data that then needs to be re-entered.
