Reading back, I hadn't noticed that the copy you took of this gave an different error. That makes me more confident that it was a file system corruption of some sort. Hopefully it isn't a failing SD card. If it happens again, I'd replace the card.

As to BookReader.sqlite, forget about it. It is completely and utterly uninvolved in anything that you have been describing. It will only be used if you have a Kobo Plus account. Calibre does absolutely nothing with it. It has absolutely no idea the file exists. If you think something is wrong with it, just delete it. The device will recreate it.


I don't think it is a software issue. I think it is more likely that the file system was corrupt somehow, or possibly the SD card is failing.
Actually, in the first post I said I did replace the SD card after the first time this happened because it looked like corruption. Also, I wasn't sure a factory reset would rewrite files that were corrupted, so I used the original image and let it upgrade through Kobo.

The fact that it's progressive, first not loading covers, next not deleting books, eventually not being able to manage at all with calibre looks like corruption. This time I did not look to see if I could access the drive, didn't seem like it mattered when a reset was inevitable.

Thanks for helping.
