What brand are the drives? If they include Seagate, Maxtor or Western Digital, the free TrueImage from Seagate (DiskWizard) or WD (DataGuard TI WD Edition) will resize the partition as it clones. I've just changed the system partition size as I cloned between between my laptop's WD and a Vertex SSD. There just needs to be one of the relevant manufacturer's drives in the system, e.g. Seagate or Maxtor to use Seagate DiskWizard.
