Release: 2.63 [22 Jul, 2016] doesn't work with Kobo Aura

[Waldo Espinosa]

When I connect my Kobo Aura, I get the following message:

Error communicating with device

CorruptError: database disk image is malformed

Traceback (most recent call last):
  File "site-packages\calibre\gui2\device.py", line 87, in run
  File "site-packages\calibre\gui2\device.py", line 503, in _books
  File "site-packages\calibre\devices\kobo\driver.py", line 1748, in books
  File "c:\cygwin64\home\kovid\sw\build\apsw-3.8.2-r1\src\cursor.c", line 231, in resetcursor
CorruptError: CorruptError: database disk image is malformed

calibre, version 2.48.0 Operating System: Windows 10 Home User, device works perfectly well, previous versions worked well.

Thanks,

Waldo

That error means there is a problem with the database on the device. It is corrupt in some what that is seen when calibre reads it. Depending on exactly where the problem is, this might not be noticeable when using the device. The device largely works using an in-memory copy of the database, problems like this are mostly seen when the database is reread. The problems are usually noticed as the reading status being lost or books disappearing from the home screen.

Unless you have a recent backup of the database, the only real fix is to sign out of your Kobo account on the device and then back in. This will create a new copy of the database. Unfortunately, you will lose the reading status and annotations for sideloaded books when doing this.

Problem solved, did as you said, thank you very much,

Best regards,
