Which is of course why I asked if the processing screen was shown. But, I did forget to mention that if there are errors in books that the firmware rejects, then the other books in that batch will not be be processed.

You could try deleting the files manually from the file manager in your OS and try again from within Calibre. The safer way though is logging out of your device completely, setting it up again and starting with a fresh database as there could be residual info from writing to the database with Calibre that could cause problems in the future...
With Kobos, it is *really* important that you *always* wait for the device to disconnect itself after ejecting safely,
Yes, it is important to safely eject the device. And wait for the OS to tell you that it has been ejected. After that, it is safe to unplug the device.

that is the only way the software will start looking for new books and handle them properly.
I'm pretty careful about ejecting properly, but I've never had any problems with books not being recognised because I unplugged a bit quickly.

Also, never delete books that *have* been recognized other than from the device software itself! Even though you could do it with Calibre (but never from the file system!), it is safer as that will definitely be registered in the database.
The rest of this post (the bits I didn't comment on directly) is complete BS.

Unless the database is already corrupt, logging out of the devices and back in is not going to help with this problem.

When sending a new book to the device, calibre doesn't actually update the database on the device. After the send, if you have the collection management options enabled, the books are put into collections. If for some reason the book is not processed, these will still be there, but they are completely safe.

It is perfectly safe to delete books from the device using calibre. The KoboTouch driver does exactly what the device does. I have spent a LOT of time making sure of this. And if anyone does have a problem, please tell me. I'll try and work out what is going wrong and fix it.

It is even safer to simply delete sideloaded books from the device. The firmware knows how to handle this. It will remove the missing books from the database in exactly the same way as if you delete the books through the interface. Some very old firmware didn't do this. But, when you tried to open the book, a message about the book missing was displayed, and the details were removed safely.

@johnnyb: Please don't spread misinformation about something you obviously don't know anything about.
