There's a book that can't be converted (neither viewed since it takes long for opening the viewing window and at the end is displayed with a mess of unreadable characters) so I'm looking for advice.
I was not able to convert that book using Mac versions of both Kindle and Calibre, neither with Windows versions...(but same DeDrm plugin version 10.0.2)
I don't realize why ONLY that book (till now at least, since I tried with just a few books...) can't be converted  |
First, I suggest that you rethink using PDF as your archival format. PDF locks you into a single screen size, font, and font size. You will be unable to change things later if your device or eyesight changes. EPUB is probably the best archival format for ebooks. Keeping the original format without DRM is also a good idea.
Second, there are several variations of MOBI format. It is likely that the garbled appearing book is actually a PDF with a MOBI wrapper. The KindleUnpack plugin can extract the PDF from it if this is the case. (Calibre handles this variant only if it has a AZW4 extension. DeDRM sets the wrong extension when run under calibre 5.x)
