I think I got it figured out....can someone confirm that the following code will mount my external hard drive ("Macintosh HD Clone") prior to running SuperDuper, and will also unmount the drive after the cloning process has completed...

on beforeRunningCopy()
	tell application "Finder"
		if not (exists the disk "Macintosh HD Clone") then
			try
				do shell script "diskutil mount `disktool -l | grep 'Macintosh HD Clone' | sed 's/.*\\(disk[0-9s]*\\).*/\\1/'`"
			end try
			
			repeat while not (exists the disk "Macintosh HD Clone")
				delay 1
			end repeat
		end if
	end tell
end beforeRunningCopy

on afterRunningCopy()
	delay 2
	
	tell application "Finder"
		if (exists the disk "local_home_backup") then
			eject "local_home_backup"
			delay 2
		end if
		eject "External HD"
	end tell
end afterRunningCopy

Thanks!
