After the problems I had following changing my email (see https://www.mobileread.com/forums/sh...02&postcount=1), I reinitialized the Forma - on November 17 - and started the painful process of loading my circa 5000 books on the reader. It was even more painful than usual, and I only finished it yesterday, to discover that 78 of them had transferred as epubs instead of kepubs. I really prefer kepubs (many of those books have notes), so eliminated them from the reader, and started loading them again piecemeal. I tried to convert them to kepubs in Calibre to help the process, but only 35 conversion were successful. I unplugged the reader, and saw that there were only 41 epubs, so 2 of the epubs were converted on the go.

But when I plugged it in again to update the metadata I had an error message

Then I turned the reader off, replugged it and got the same error message

Spoiler:

I hope without hope that it is not a problem with the database that would mean I must reinitialize again, and restart the whole painful process.

Can someone tell me what the error message means?

EDIT: I tried a third time, after turning off both PC and reader, and it worked. Pity I can't change the title to "solved". But I would still like to know what the error message means.
