Problem reading Kobo

ccowie · 12-22-2012, 04:50 PM

My kobo has worked fine up until recently. I now get the following error:

calibre, version 0.9.4
ERROR: Error: Error communicating with device

database disk image is malformed

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 85, in run
File "site-packages\calibre\gui2\device.py", line 470, in _books
File "site-packages\calibre\devices\kobo\driver.py", line 310, in books
DatabaseError: database disk image is malformed

Can anyone help me?

That means the database on the device is corrupt. It generally happens because it was unplugged from the computer without being ejected.

Unfortunately, there isn't a good fix. If you happen to have a backup of the database, you can restore that and everything should be OK.

You can try logging out of the Kobo account on the device. This should create a new empty database. Then log in again and do a sync with Kobo. After that, the sideloaded books should get added after restarting the device or connecting it to the PC.

If that doesn't work, you will need to do a factory reset. That will clean everything up and install the latest firmware.
