[Kobo] IOError: disk I/O error

Manucv7 · 04-02-2017, 02:19 PM

Hello Evryone,

I've connected my Kobo Glo HD for the first time in a couple of months and when I open Calibre 2.82.0 (64bits), I have the following error :

Quote:

IOError: disk I/O error

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 88, in run
File "site-packages\calibre\gui2\device.py", line 511, in _books
File "site-packages\calibre\devices\kobo\driver.py", line 1707, in books
File "site-packages\calibre\devices\kobo\driver.py", line 167, in get_database_version

File "c:\cygwin64\home\kovid\sw\build\apsw-3.8.2-r1\src\statementcache.c", line 386, in sqlite3_prepare
IOError: IOError: disk I/O error

I've search this forum and found a few mentions of such error (database is corrupted) and possible fix (reset factory settings) but it didn't solve it.

So basically, I can't add any books to my Kobo using Calibre and I don't really know any other way

If anyone can help, it would be greatly appreciated.

The corrupted database error has to be fixed with a new database (either sign out of the account on the device, or a factory reset) or restoring a backup. If the corruption happens immediately after a factory reset, then something else is going on.

A likely reason is the internal SD card in the device is failing. If it is, then any update to the card could fail and be lost. That sounds like what is happening. But, you should also check what happens when you don't use calibre.

If you connect the device to Windows, does it show the device properly? Does it get mounted as a drive? Can copy a book to the device manually? When you eject the device, does it get processed an appear in the library on the device? Is it still there after restarting the device?
