Can not mount copy of image file (ddrescue): "can't have a partition outside the disk"

Question

I'm struggling for days now moving my old Windows XP installation to a new hard disk, because the old disk is failing.

Long story short:

I successfully created an image of the entire (failing) disk and was able to mount it in Linux. I now want to copy it (the image file) to another disk, but the copy seems to have an error (see below)

What I did

(among many other things)

I found this excellent tutorial: https://www.technibble.com/forums/threads/guide-to-using-ddrescue.48269/

cloning failing drive to .img with ddrescue -d

• installed Linux Mint 17 on another drive in the PC
• bought a new 3 TB hard disk
• cloned the entire failing disk (Seagate, 500 GB) with ddrescue to an image file on a partition of the 3 TB hard disk
  sudo ddrescue -d /dev/sdc Seagate500GB_ddrescue3.img Seagate500GB_ddrescue3.logfile

Result:

tested the image and was able to mount it in Linux

sudo mkdir mountpoint

sudo mount -o loop,ro,offset=70605834752 Seagate500GB_ddrescue3.img mountpoint

Copied the .img file to another disk (hfs+ volume)

In the Linux file explorer (Nautilus?) I copied the .img file to another disk. Unfortunately I only had enough space on a disk formatted hfs+ (journaled), so I had to mount it with write permissions in Linux (like described here ) and copied the .img file to it.

now parted can not list the partitions of the copied image:

still on the Linux machine with the hfs+ drive mounted after copying:

with sfdisk I can list the partitions:

the original image shows one more partition!

Question

What have I done wrong? Is the copied image file damaged?

Can I fix it or do I have to chose another method to copy it somewhere else (maybe with dd=?
