Hi Dave,

thanks for the hint. As I was not sure I did again the whole process. So, I open the image with the "Open Disk Image" command of the File menu.
Then I drag the drive icon that appear a the bottom of the drives list on the left hand-side and finally the destination disk that needs to be erased and restored.

The process start and when almost finished (95%), DiskUtility throws the error.
Any other idea?
Thanks a lot
