partclone does not include the NTFS's backup boot sector, which is the last sector of the partition. The reason is because NTFS defines its own size has "1 sector less than partion's size" (see [1]). This prevents us from mounting the image with recent version of mount (or could it be the NTFS's "driver"?).
It would be great if partclone_imageinfo could help us to detect this situation.
