If so, have you changed the send-to-device template? Or used some other software to load the books? What I am really wondering is whether the book is in fact on the device twice, but in two different places. If this is true, things will get confused. Calibre's author and title matching will match both to the same book, probably creating two lines that could end up pointing at the same file. The Sony software will find both and create two records, but its collections will likely get messed up.

If you delete one in calibre then disconnect, the other should come back on the next connection.

Bottom line: if you change naming conventions, it is best to clean all books off the device and reload. If you use more than one piece of software to manage the device, ensure that the same book is not added by both of them.

Here is an example:

1. Send new book to device - result: one entry on the list in Calibre for Card B.
2. Send the same book to device again - result: two entries on the list in Calibre for Card B - both showing the book to be in the same location on the device. Confirmed only one book present on the actual device.
3. Disconnect device
4. Reconnect device - result: the book is still listed twice in Calibre.
5. Delete one of the entries in Calibre - result: error message as follows:
   

   =====================================
   ERROR: Error: Error communicating with device
   (3, 'The system cannot find the path specified')

   ==========================================

   The book is no longer present on the device but there is still one entry in Calibre's list for Card B.
6. Delete remaining entry from Calibre's list - result: everything now back to normal.
