error connecting with ereader

[Odyssee]

When I try to connect calibre with my kobo sage I get this error message:

calibre, version 6.22.0
ERROR: Error: Error communicating with device

CorruptError: database disk image is malformed

Traceback (most recent call last):
File "calibre\gui2\device.py", line 104, in run
File "calibre\gui2\device.py", line 556, in _books
File "calibre\devices\kobo\driver.py", line 2045, in books
File "calibre\devices\kobo\driver.py", line 1913, in get_bookshelvesforbook
apsw.CorruptError: CorruptError: database disk image is malformed


I already deleted the metadata.db file and then restored the database. To no avail. Any help is much appreciated.

[edit] I also did a reset to the factory settings on my device. Didn't work, again the error.

The database on your Kobo is corrupt. Unless you have a recent database backup, you will need to log out and log back in basically starting over.

If you haven't done so,take time after you fix things and set kobo utilities to back up the DB. I bumped the default copies to 10 as I frequently connect. YMMV a device (restore is a manual file copy+rename)

As you can see, it also supports multiple Kobo's, even if they are not the same model (No, don't think of using a db from a different serial. I have no clue how bad things will get )

I used my database from my Aura H2O on the Libra 2 and nothing bad happened. I did it when I was setting up the Libra 2 so if something did happen, I could reset everything and start over.

Not a good idea with a Sage to just overwrite from a Kobo that has no note taking. The config file has extra stuff, though I don't know how it tracks notebooks. It can actually import a notebook from an other Sage or an Elipsa.

I did have an original Aura HD H2), a version c Touch and a Nia. I still have Libra, Libra 2, Sage and Elipsa.

Just because copying a database from one Kobo to another Kobo worked for Jon, doesn't mean it will always work or ever work for someone else. You'd need to have at least the same files the database refers to copied also and the same config.

I think I did everything to solve this problem:
- sign out/sign in
- another (new) USB cable
- another USB port on my laptop
- downgrade of the Kobo firmware just to be sure
- factory settings reset (twice)
and nothing helped. As soon as Calibre 'sees' my device, there is the error message. When I try to see what is in the main memory on the device, there is nothing (although there are books on the ereader).
Strange thing is, I can still upload books to my Kobo Sage via Dropbox but I don't like that method, I vastly prefer Calibre.

I copied all the eBooks as well.

Update and Behold.
I couldn't resign myself to the horrible situation with the communication error. So third time lucky, I tried another reset to the factory settings. Everything is okay now. I transferred my Calibre database of 2000 plus without any trouble. Why it didn't work the previous 2 attempts, I can't fathom.
