Aura HD Ghost meta book entries in collections

booklover6 · 09-19-2014, 09:10 AM

Weird problem, here. I have multiple Kobo readers, all set up the same way.

Okay, just noticed it is on my Aura, too. Both are running 3.8.0 with collection management handled by Calibre. All are side loaded kepubs. In a collection, there are hundreds of meta data entries for books that are not on the device. I went through 500 pages under the "books" heading, and none of them show up there. I then removed all of the books, via Calibre, from the collection. Now, for example, one collection, which is empty and so shouldn't even be on the device, has 60 metadata entries.

These were all on the device at one time. I add and remove books frequently, depending on my whim. I've never had this happen before. I checked my Glo and it is not doing it, although I haven't connected it to Calibre recently. I updated Calibre to the latest today, and no improvement. Still tons of ghost listings. And sometimes duplicates, if I have re-added the book at another time. The book is there, and so is a separate ghost metadata listing.

Metadata is set to automatic management.

Both of these devices had SD cards with books on them not long ago, but no longer do.

On my Aura HD,I've just hand deleted collections full of empty metadata listing, and reconnected to Calibre. Cycled with out adding/removing or doing anything, ejected. The collections with only metadata are gone! So that worked.

Any idea what could have caused these ghost entries?

Do you ever do WiFi (or Desktop) syncs with Kobo? There have at times been issues with shelves reappearing, or getting garbage contents. Do you have the option selected on the Kobo to just display downloaded content (Library Settings | Only show downloaded items).

I'm sure davidfor will chime in with more ideas.

Something similar happened to me, I think it was last year, I went crazy trying to remove the entries that had no books, I think it had something to do with a problem in the database because since I couldn’t solve the problem with caliber If I remember correctly I logged out on the glo and it solved the problem, but I think I lost all the statistics and had to send all the books to the glo again.

I don't normally turn on wifi or sync with desktop. I don't believe I have done so with these 2 devices recently.

Also I did run a data base check on the HD, all ok.

Well at least removing the collection and then allowing calibre to create a new collection solves the problem.

Mine used to mirror first entries in collection on last page, with same title and unknown author. I never could figure why or how to get rid of them.
