I am trying to mount an image of a macbook pro obtain with dd. I have use this strategy to adapted the syntax of my mount command.
I have use the following process
- create the image:
sudo dd if=/dev/sdc of=ddDisk bs=300M status=progress - obtain the property of the image with
fdisk -landtestdisk(see below) - create an empty directory:
mkdir test - try to mount the main partition (
ddDisk2) with the following command:sudo mount -v -t hfsplus -o sizelimit=498887294976 ddDisk2 test
I obtain the following error message: mount: test: failed to setup loop device for ddDisk2. I am not sure I well understand this message.
Results of fdisk -l

Mount only the partition, not the whole image.
losetup -f /dev/loop4 ddDisk -o 209735680 mount -t hfsplus /dev/loop4 test (209735680 is the first byte of the partition)
