What are the differences between the two machine? Do they have the same 
controller?
Have you checked if putting the cloned drive in the original machine as sda 
works? That would confirm the clone process worked? If it fails you clone 
process failed. 

Are you 100% sure the sdb disk is as large are larger?
How did you run the dd command? Did you boot from a live cd or what?
Did you use a clone program like g4u, g4l, clonezilla?
