 Initialize and clone to the destination disk sdb?  (yes/no): 
 ```
+Note that if I had partitioned the 64GB disk with more than three
+partitions it would have been more difficult to clone down to the
+32GB card.  If there had been 4 partitions, then a smaller disk has
+to be large enough to image the sizes of the first three source partitions.
+If the disk is too small for that, then an initilize clone would be
+limited to a two partition clone as the next example shows.  The other
+alternative would be a manual partition.  The take away is that you need
+to consider how you would be cloning to smaller disks when you partition
+a larger disk for a Pi.

-#### 10) Cloning to manually partitioned hard drive with swap and extended partitions
-This is an additional demonstration of flexibility in partition structure
-when partitions are manually created.  The manual partition included a swap
-partition I might use later and an extended partition with two logical
-partitions. I run rpi-clone from a SD card boot and it will sync only
-the first two partitions:

-#### 11) USB disk clone to large USB disk
-A final example shows a clone from the hard drive set up
-in example 11 to another hard drive. For this example I'm
-plugging in a drive I happen to use for backing up my desktop,
-so the partition types won't match and rpi-clone will want to do an
-initialize.  rpi-clone duplicates the partition structure and makes
-the swap partition.  This example gives a clue
-how rpi-clone would work if run on a Linux desktop.
