I've been working on loading books onto a new kobo aura from calibre. After I re-mounted the kobo, calibre's "On Device" column changed to empty for every book, sent or not.
In this state, I sent a new book to the kobo, and it arrived, but calibre did not set the "On Device" field for the book. Eventually calibre gave the "database disk image is malformed" popup. I didn't see any other indications of trouble while I was sending the books. I sent about 15 books at a time to the device, but did not disconnect the kobo between every set.
On the kobo side, it lists the books, but the collections are goofed up. For example there are empty collections for some series even though the books are present.
This happened once before. I deleted the book files on the kobo, reset, and started over. Thankfully, calibre held onto its list of added books.
My setup:
The calibre and kobo fw versions are less than a month old: mac 10.10.5; calibre 2.50.1; kobo aura fw 3.19.5761
All books are epubs. I have about 170 books in calibre. Added kobo Utilities plugin 2.1.0. I don't know what kobo device driver is being utilized, but I customized koboTouch and something produces kobo collections based on series. I believe I am always disconnecting the kobo properly.
I started calibre in debug mode after getting the "database malformed" message. Output is shown below. I ran the kobo db query shown at the end of the debug output from the command line. It worked fine. Is the malformed db Kobo's or calibre's?
I would very much like to have calibre coordinate with the kobo. That is, have the "on device" column work reliably, and secondarily have the kobo collections work. I don't mind coddling the loading process in order to have success or to help pin-point the problem. I'm already thrilled my books are organized with so much more info using calibre and the kobo. With the options I could access on my old color Nook with a bad screen I could only look up epubs by file name.
Any advice on a good way to start over and to transfer books to the kobo properly? Should I step back in kobo fw? I'm glad to provide any other information, and happy to accept any hints about things to try.
Thank you.
