I tested it with other SD, and the problems continued. Then I flashed and install PRS+ and it continued with the problem, so it is not a problem of calibre, the card or maybe the reader, but a problem with my books.
I noted I have 50 books with more than 5MB (even 12 books > 50 MB), basically pdfs with scanned images I usually dont use in the reader, so what I have done is to select 230 books, slow file size and more commonly used at the reader and they all now are showed in the file list.
Conclusion: a max nodes directory problem, as you said, or problems handling so many big files. I suppose.
Now, just only as curiosity, do you know what are the max nodes you told??
Thank you again,
