Calibre "forgetting" what books were sideloaded

[glazedbelmont]

Hello,

I've been using Calibre to organize my "fairly big" book and manga library but recently, it's been seemingly corrupting the metadata on my BOOX Go Color 7 which causes it to check for every book in the folder then report that 90% of them aren't On Device, see image:


This has happened countless times and I have to re-send to the device, is this a known issue or am I doing something wrong, I always eject the device and don't unplug it while it's writing, Calibre seems to see it on the "Card A" view though, see image:
.

I have tried deleting the driveinfo and metadata files, restarting the device and the computer but it's happened again, this has been going on over the course of a few days.

If you match a book on the device manually to a book in the calibre library, does it stay matched? I'm wondering if the multiple titles being the same are causing the issue. I haven't noted that issue on a Kobo but then I would use Attack on Titan Vol. 06 as the book title and then repeat the title as the series name and the volume number as the series index.

There might also be an issue with how the actual file name on your Boox is being created. Do you have a save template set in the Boox driver?

Bounce a query off my daughter and she has read some of the series and uses Hajime Isayama as the author.

Edit: added image from one book series I have with the identical titles.

I do have a template in python to export, I think I can see the issue now.

Here is the template for info sake:


Calibre is trying to grab the author from the filename but since my stuff is named:
Series - Vol. Series_Index "- Title" (this part is optional), it's importing it incorrectly when it has to rebuild the database.

Is there a way for Calibre to not do that or am I just SOL due to how I'm naming my exported files? I'm guessing the easiest way would be to change my template but I would love to keep how I'm naming my files so it's simpler to organize.
