KOBO Elipsa error communicating with device

[Sandor]

For some days now I have problems when I connect my Kobo Elipsa ereader to my computer. Seemingly nothing has changed so this happened out of the blue.

After connecting the device and opening Calibre 7.4 I get the following error message:

calibre, version 7.4.0
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 558, in _books
File "calibre/devices/kobo/driver.py", line 2028, in books
File "src/cursor.c", line 240, in resetcursor
apsw.CorruptError: CorruptError: database disk image is malformed

Anyone seen this and what can be done?

Thanks in advance

Welcome to MR.

The fix is the same for almost all modern Kobos.

Sign out on you Kobo, then sign back in. You will lose your reading position and stats.

In general, I found :
1)Always have the Kobo showing its Library screen before connecting (not reading a book)
2)Wait for Processing on the device to complete (after ejecting in Calibre) before unplugging. (that works for both of my models. YMMV with others)

All that, and 'My Books' or 'Library'.

I also don't tap connect too quick after adding cable and I don't unplug cable / or reconnect till also the added ebooks appear at the top of unread, which is a number of seconds after the black screen with bargraph. I 'eject' from Calibre.

Also make use WiFi & BT are off.

SideloadedMode=true may also help, however with multiple Kobos here I've not had database corruption since I started that regime some while ago. I checked database on lat two Sages connected and OK.
