Since your books work, I suspect your source of those others has applied DRM or otherwise damaged them.
(Calibre can store and deliver books via USB, with DRM, just not make any changes)

Thanks for your reply, I would have said "Never ending" .. sorry for my poor english.
OS is Windows 10
Actually, the books on which I got a never ending check doesn't appear to be DRM protected because
It can be opened and read into Calibre
If you try to convert it, the usual window saying "This book has DRM... cannot convert" doesn't apper
There is no suspicious file into it that could contain protection.
So I just wonder what makes the check running with no end.
