Restoring Database effects ORIGINAL_EPUB format display

MartyTX · 08-13-2012, 09:29 PM

I noticed that after "Restore Database" is run, the main screen "Formats" column no longer shows ORIGINAL_EPUB as a book format.

The ORIGINAL_EPUB book itself is not deleted (it is still in the book folder), but it's "existence" is removed from the database.

Because of problems displaying some book covers on the Nook Simple Touch, the Nook forum recommends re-converting Nook to Nook. Seeing ORIGINAL_EPUB listed in the "Formats" column is an easy way to tell if the Nook to Nook conversion has already been done.

Why is the ORIGINAL_EPUB format removed from the "Data" table in metadata.db?

Thanks,
Marty

That is a bug in the restore process, fixed in the next release. You should be able to get back the original_epub entries by running a library check.

Thanks for the prompt response.

I'm trying to learn about the MANY features of Calibre, and keep a small "TEST" library as my sandbox so I can't do any real damage.
Restoring the database was with the TEST library. I just wanted to see how it works.

The more I learn about Calibre, the more I realize how little I really know!
