cover.jpg did not exist when this move operation was started

[canpolat]

@BetterRed, @theducks and @kovidgoyal thank you for your responses.

Here is what I did today: I deleted the whole library. Then, went back to the old PC and used the Calibre Export to export the library into the external HDD. Then connected the external HDD to the new PC and started a Calibre Import from there. Everything went OK. But when I tried to modify a title I got the exact same error: "cover.jpg did not exist when this move operation was started"

Then I went on to try @BetterRed's idea. I uninstalled the 64 bit and installed they 32 bit version. And the error was still there:

calibre, version 3.8.0

I only see this error in this library. I have two other libraries located next to this one and the work fine.

This does not look good. There is definitely something wrong with this library (after the transfer) and I cannot tell what.

I started thinking about adding this whole folder again but that will cost me a huge amount of time if I lose the metadata. I also need to keep the Calibre Id's in addition to the metadata (due to some workflow reason).

So I tried the calibredb command line interface. I think if I can keep the Calibre Ids intact, I can try putting together a script to move the metadata from the old database to the new one. But after some testing I noticed that the add_format function does not populate the cover:

calibredb --library-path $LibraryPath add_format --duplicates $Id $DocumentPath

Few of the PDF files also contain metadata as embedded XMP and the add function did not read the metadata either (when I add the document via GUI, the metadata is populated for those that have embedded metadata).

So, before losing all hope, my question is: is there a way to use the add_format function so that it reads the embedded metadata?

That should have resolved any Linux->Windows issues, as per Kovid's advice.

What about Safe Mode - although given next sentence I don't have much hope.

Well that must mean it's something peculiar to the problematic library - not Calibre or Windows. Here's a couple of ideas

• Move the Library folder with Windows to say C:\Calibre\<library name>, you'll need inform calibre of the new location via the Create/witch library tool.
  
  If that works then that would suggest there maybe something wrong with the NTFS MFT, if it doesn't work that would suggest there is definitely something wrong with the NTFS MFT. In either case I'd be worried about the drive.
  
• Try creating a fresh library and copying books into it from the problematic library - using calibre's Copy to library tool (by default it's in the book list context menu). First try copying just a few books. If the fresh library works, then copy and delete the rest.

Export / Import CREATES a Library. No need to add, it should be ready to go.
Once you are happy, you could combine (merge, AKA Copy to Library) with an existing Library, already on the system

Should be, but it wasn't was it - this is what he wrote in post #16

I haven't answered the questions he poses in post #17 because I am not sure of adding from an existing library via the command line and getting all the metadata from the opf files.
