Two tips I'd like to add to this method:

1. You will most likely have to run this with 'sudo'. Mine gave a permission denied until I did so. So, you would enter sudo asr -source /Volumes/source -target /Volumes/destination -erase -noprompt

2. If you are copying your main HDD and it's name is Macintosh HD you will have to type it as Macintosh\ HD. The backslash let's Unix know that the space is part of the name, not the end of it.
