These left over books were books that the device didn't fully process, and thus didn't put them in the database. This is why calibre didn't recognize them.
Most likely, these were corrupted books. It would have been interesting to make a list of those, and then see if they are in calibre, and if so, check if the file on the device is the same as what is in calibre.
There's a number of possibilities I can think of:
- These books are also corrupt in calibre, in which case your problems will reoccur as soon as you transfer them
- These books were corrupted during transfer but somehow didn't get noticed
- These books were added to the device by some method other than calibre
- These books were corrupted after being transferred, possibly by bit rot on the sd card or something, and the database was reset, forcing them to be re-imported
- Somehow, the book was sent to the device from calibre more than once, but only one copy is corrupted.
If this happens again, it might be useful to check and see if there are books you sent to the device from calibre, but calibre doesn't show as being on the device, indicating it didn't scan correctly when importing books. Then, you'd have to hunt down where the corrupt file is on the device and manually delete it.
