Tried to send a book to my wireless Kobo today using Calibre and got this error message:
database disk image is malformed
Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 68, in run
File "site-packages\calibre\gui2\device.py", line 310, in _books
File "site-packages\calibre\devices\kobo\driver.py", line 167, in books
DatabaseError: database disk image is malformed
Before I do anything I wanted to check that resetting the Kobo to the factory default state (using the instructions given above) is what I should do to fix it.
