Ghost 14

I am lost on this one.  I run Ghost 14 both on my office PC and my laptop at home.  In both situations, I use a USB external hard drive for the image.  Both systems have a virtually identical drive configuration (3 partitions on the hard drive).  On the PC, there is no problem creating a recovery point set.  On the laptop, however, Ghost will not allow me to create a recovery point set, only an independent recovery point, making it impossible to add just the changes and forcing me to do a complete backup every time I want to do a backup.

 

I have looked through Norton Help for the program, the Norton posts and the Microsoft articles regarding mounted/unmounted drive, and can find nothing of use.  Any help on this would be greatly appreciated.
