I had a little issue with my Aura. I connected it to calibre, removed some books from the main memory and added them to the card. When I disconnected it, it took forever to process the new books (probably around 150), and at the end the database was corrupt: couldn't connect it back to calibre, no "currently reading" books, no cover thumbnails...
Fortunately, the Kobo utilities plugin had saved a backup of the database, so I could copy it back to the device and now at least everything looks normal, and I hope I can recover my annotations.
Anyway, since I removed some books in the last session, I expect the restored database contains references for these books, which are no longer in the device. So my question is: Is it possible to fix this? Rebuilding the database will probably take forever again, but can it be done? Or will the device it fix it by itself? I guess the books in the card will be reprocessed again, if needed, when I insert the card, right?
