Amazon removed books from my Kindle

[DNSB]

The books were actually deleted. I didn't look at the .sdr directories. I didn't make any annotations since these were not ebooks that I was editing/formatting which is my only use for annotations on my ereaders.

Where KF8/azw3, azw4, KFX, mobi, azw, etc. are used. In that use, .mobi is used for unprotected files and .azw is used for DRMmed files.

.azw is the file extension Amazon uses when KindleForPC download them.

Did you take the time to read my message before you posted your response? Pay special attention to the part that I bolded in the quote above. BTW, K4PC is another way of saying Kindle for PC.

Thanks again.

I think we can provisionally conclude that when books vanish from the UI but the book files remain on the device that the cause is something other than the cdetype in the EXTH header being set to EBOK by some non-amazon process. (And that when people report disappearing books they should be clear about whether the book file was actually removed from the ereader's storage.)

I seem to remember back when I first got a Kindle that sideloading a book, like a publc domain book, through a USB connection and the computer's file manager resulted in the Kindle treating the book as a "personal document". It did not show up in the book list and covers did not display. It went into wherever a random PDF document goes.

But I found out Calibre "fixed" the problem somehow and was able to sideload a book onto a Kindle such that it showed up in the "Books" list and covers were displayed. I have no idea how Calibre did it, but that's why I started using it.

My guess now is that's the result of the difference between EBOK vs PDOC.

Maybe that's not the way it works now, but I believe that's the way it worked back when I got my shiny new Kindle Keyboard.

MyClippings.txt is just a log file. The kindle only ever writes to it, never reads. The loacations of the highlights for a book are stored in a file in the .sdr directory for that book.


Copy the entire documents directory on the kindle to a computer, then delete or move all the books and .sdr directories in the documents directory on the kindle. Then copy the books and .sdr directories from the computer back to the documents directory on the kindle over USB. Then safely eject the kindle. The books should show up as "new" and when you open them the highlights should be there.

If you use any other method to tranfer the books, the metadata might change in a way that the contents of the old .sdr don't correspond to the book files then they might not be recognized as matching.


If the kindle is jailbroken, it might be possible to manipulate cc.db to make the books show up again, which would be easier for some and next to impossible for most.

Ah many thanks. OK, i should have clarified, Kindle is NOT jailbroken, but I did use Calibre to put the books on in the first place. This is probably why your suggested method above didn't work.

Is there a route I can take to try and get the Kindle to see the books and their highlights again in this case?

Thanks again
