Kobo Forma possible database corruption, books keep "disappearing"
I think this is a just-me problem and not a bug but I could use a hand fixing up my Forma.
FWIW I'm a senior software engineer, so throw technical solutions at me if that will help me get things fixed.
My Forma contains exclusively books side-loaded via Calibre, with the Dropbox and Pocket integrations active.
A few weeks ago, my Forma froze up. It sometimes does this when I have charged it and usually a hard restart (hold down the power button) resolves the issue. This time, it took longer than usual to restart and when it did, almost all of my books had "disappeared".
When I plugged it into my machine (MacOS) I was able to open up the DB and still see all the books listed, but when I looked at the stored files, they were all gone.
I did a factory reset, then bunch of clean up via Calibre, resynced the books and it seemed like everything was okay again for another week.
Then last night, when I had to do the hard restart again after charging, the book I was reading had disappeared along with a bunch of others. I read a short story and when I closed that, it also disappeared from the library.
I'm going to reopen the device on my laptop again later today, but I'm wondering if there's something corrupted in the file system or the DB that would cause this.
Is there a way to completely reset the entire device? Like reinstall the OS and reset the entire DB?
Is there any chance this is a irreparable or is there hope here?
Like I said, I'm comfortable poking at the innards, running SQL queries, etc so I'm open to all solutions.
