Its been a while since i used Clonezilla but in my old job working for a schools IT dept it was used regularly to restore the OS on PCs after a HDD died from a master image.
I do recall that it couldn't restore a partition to another a disk smaller than what the original one was you were cloning from, even if the actual amount of data to copy was lower.
Eg if you had a 250GB partitions with 100GB of data, you could only copy it to a disk of 250GB or greater not a 200GB disk even though the data would fit on there, as Clonezilla couldn't resize partitions on the fly.
This was a slight issue if you used a different manufacturers drive where one was actually 250GB and the other was only 249.9GB. So we started leaving the last couple of GB unpartitioned on the drives to get around that problem.
Biting the hand that feeds IT
