Clonezilla is a great tool to migrate data direct from your old device to your new device. In some cases you may experience the following error in Clonezilla:

read image_hdr error=0

You can find the reason of the error in `/var/log/partcloned.log`. Often, the original file system contains error. Running fsck may help you out:

fsck /dev/sda1
# Replace /dev/sda1 with your device
