No go when I tried to add 1000 books at a time to my Glo HD - I therefore removed the Kobo add-ons and then added them back again. It seems the problem is (according to the job list) getting the list of books on device - that always ends in an error.
IOError: disk I/O error

Traceback (most recent call last):

I have since (without re-starting Calibre) just tried 399 books and got an error. So for the book transfer, it seems the problem is a corrupted file (which I have removed). I can't figure out what the issue getting the kobo's book list into Calibre is though.
ADDITIONAL INFO: I removed the file that was corrupted according to the error message and got the same message with the next file in the list when I tried again... My Glo is now only good for 300 or so books - so disappointed - it's been used very sporadically and with kid gloves and now seems "broken" because of this update.
