Calibre has been crashing the database on my Kobo regularly (about every 3 weeks or so) for about 4 months now. It's usually after hitting the 'eject device' button that I get an error message saying that it was not properly ejected, but once and a while I don't see anything wrong with the eject process. Then the next time I plug it in, I get a "cannot communicate with device" error message because the database is corrupted.
Then I have reset my Kobo, re-download all my books from the Kobo store, connect them back up the matching books in Calibre, then send the rest of my books to the device. Then I have to unplug it, plug it back in, send all the metadata again because none of the series or other info updates when it originally sends, then I have to update all the reading positions... etc. etc. This is a good 4-5 hour process and is extremely frustrating. Especially having to do it so frequently. I found an option to back up the database, but since there's no option to restore the database from that backup, it's basically a useless feature.
How do I stop Calibre from ejecting incorrectly when hitting the 'eject device' option?
Or alternatively, if that's not an option, how do I restore the database from the backup?
This is the current message I get when trying to update the metadata:
Code:
