[Kobo] Having database corruption issues?
This keeps coming up again and again, so I'm making a thread for easy linking. If a moderator is inclined, feel free to sticky it.
The current Kobo firmware has an glitch in which it occasionally fails to close the database while connecting to PC, often resulting in database corruption. If you look at the .kobo folder in your file manager, you may see an sqlite write-ahead log - which indicates that it exported to USB while the sqlite database was open. I've personally had it happen under two circumstances:
However, other users have also had it happen under other circumstances, including "at random." If you have Kobo Utilities installed in Calibre, you'll get an error about a malformed database. If you don't, you may notice if metadata fails to update or the reading position keeps resetting back to the same spot. Ensuring that you're on the home screen before connecting often (not always) helps with preventing the issue, but rebooting before connection is the most reliable way to keep it from happening. This NickelMenu config will add an easy-access reboot button to the main menu: Code:
menu_item : main : Reboot Device : power : reboot

I have made the observation, that using the option to completely shut down the device after X minutes helps to prevent any database corruption. I set this to 60 minutes and I also make sure to shut down the device and only start the device after connecting it to my PC, and I haven't had any database corruption for months.
Even though this is anecdotal at best, other users also seem to have good experiences by shutting the device completely off before connecting to a PC. EDIT You've already made the suggestion to use a reboot option in Nickelmenu, good idea. Last edited by rantanplan; 05-19-2024 at 01:28 PM. |

Would a moderator consider pinning this? It's happened again.

Then people who come to the Calibre forum are less likely to see it.

By that logic, we should also move this thread and this one. After all, it only matters for Kindle books.
