I did a manual factory reset as per the user guide & the problem book still comes up; & this time one of the light novel books did not show up on the book list but is seen using the usb connection & file explorer!

So, a factory reset and when you connected to the PC, the book was still there? In that case, the factory reset didn't happen properly. And that is wrong.

Doing the KA1 remove just reboots; the book never disappear. Do not know how the book resurrects after a reset since it is not loaded. I never use Calibre to delete a book from the device nor do I delete a book from the device when connected to Calibre.

I found a problem in that it KA1 changes or truncates the title if it is considered "too long"; the database setup get confused or mangled.

e.g. "Risou no Himo Seikatsu Volume 05.epub" is listed on the KA1 as "Risou no Himo Seikatsu V05" in the book list. but "Risou no Himo Seikatsu Volume 06.epub" got listed as "Risou no Himo Seikatsu Volume 05.epub"

For "13 Mahouka Koukou no Rettousei #13 - Steeplechase Chapter (B-T)(Roah)-v2.epub", KA1 book list truncates to Mahouka Koukou no Rettousei #13.epub"

For epubs, the device reads the metadata from inside the book. It will only use the file names if there is no metadata in the book. If you are getting those names in the books lists, then there is something wrong with the metadata in the books. Either it is missing, or it set incorrectly. When you send a book from calibre, the metadata should be updated to whatever is in the calibre library. This can be disabled,

Looks to me like KA1 has a limitation on file name size. Will have to do another factory reset & not load my light novels as the KA1 is unable deal with long file names like an Android tablet. Or perhaps it is just the nickel app.

The file name limitation is the same as the path limitation for the file system in use. In this case, the files system is FAT32 and the name length is 260 characters or something like that.

Calibre will massage the file names and paths to keep well within this limit. This is taking into account the directories in use, so it can give much shorter file names. But, that does not affect the metadata within the book.

The file name massaging that calibre does is to also remove characters that might be a problem. It will replace these with an underscore. The "#" in the above file name makes me uncomfortable, so I have just done a test on my Glo HD to check it is handled properly.

There is a bug with the forums as if one takes too long entering a reply, one is evidently logged out as the msg say I am not authorized to enter a reply or anything. I forgot to set the login to do the "remember me" thing.

If I'm taking along time to write a response, I hit the preview post occasionally to reset the timer.


The only thing I can think to suggest at this point is to format the book partition using Windows. This would normally be something I would never suggest, but it might work. Connect the device, and format the partition that is presented to the PC. The format needs to be FAT32 and use all the available space. Do a full format, not a quick format. When that is done, eject the device. It will then take you through the setup. After that, sideload a book and see what happens when you delete it.

If, after that, it still isn't working, then I think it is warranty replacement time. The last thought is that the storage is failing and needs to be fixed. And that can only be done by replacing the device. Hopefully it is still covered.
