Thanks, but I'm still not sure how to go about creating the actual clone.
Does Carbon Copy Cloner see the Preview, for instance?
Most tools will see DW's preview. When it's in preview mode, it has mounted up the original volume as read-only, (if possible) and then creates a second virtual volume, a bit like a disk image, using it's rebuilt directory structure to point to the files on the original volume, also mounted read-only. So any tool that can work on virtual volumes (disk images), which most can, should be fine with that. Just so long as it doesn't try to unmount the volume (or write to it) during the copy/scan/whatever. DW freaks out a bit if one or both volumes are unmounted while being previewed. The two volumes will look very similar, so make sure you clone the correct volume.
