Following up, I have been using my Clara for about a week after a factory reset. Last night I finished a book and when I tried to remove it, it was not completely removed. The book still showed in the list but when selected, I get an error that I am not authorized to read the book.

I connected and tried to open the databases, KoboReader.sqlite opened and the test showed no problems but BookReader.sqlite gave this error.

Could not open database file
Reason: disk I/O error

When I did this after the reset, both were readable even though BookReader.sqlite required a password.

So I closed SQLitedatabasebrowser and opened calibre with no errors and calibre let me delete the file from the reader. When loading a couple of books, one loaded and the other threw an error. That book did show up in the folder on the reader but without a cover.

After the last reset, I made a copy of BookReader.sqlite, so I deleted the one on the reader and replaced it with the copy. This worked!

I know it's not the way to correctly troubleshoot and the disk I/O error points to the sd card, but after so many times going through this, I wanted to see if BookReader.sqlite was the culprit and it seems it is. Why it keeps happening is the real question and I guess I need to try yet another sd card.

So my issues are still ongoing.....
