The problem I'm having with my Clara started a few months ago and despite all my efforts it keeps coming back.
My Clara was working fine for several months but sometime after the update earlier this summer it started having problems.
I added a few new books from Calibre and the covers did not load. Connecting repeatedly didn't make a difference, but when I used the Kobo Utility to force the covers, they showed up. This went on for a week or so until one day I finished a book and selected remove. It did not delete. I tried a couple of more books that would not delete either. When I connected to Calibre version 4.23.0, this message popped up.

ERROR: Error: Error communicating with device

CorruptError: database disk image is malformed

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 90, in run

CorruptError: CorruptError: database disk image is malformed

I did a factory reset, let it upgrade, applied patches and all was well. A few weeks later I started having issues with covers not loading again.

Since I had upgraded to 32gb micro sd, I installed the original image to a new micro sd, let it upgrade to the latest version, applied patches and all was well.

Earlier this week, covers quit loading and today when I connected to Calibre (still on 4.23 - KoboTouchextended driver) I got the database error again.

Since I've had this happen with 2 different sd cards, they should't be the problem.

Maybe I've done something squirrelly with the patching without knowing??

Any ideas would be appreciated.
Thanks!
