I think you are taking the original querent's "exact clone" too
seriously! 

Using "dd" will copy every sector on the disk, whether used or not!

This will take "forever" on a large enough disk.

It may be better to use some sort of _file_ copying tool like "cp",
"rsync", "cpio", "tar", "unison", ...
