I.  Installing drive into the HDD Duplicator 
Note: Make sure that the capacities of the target hard disks 
are equal or larger than the source hard disk.
For example, on the label of the hard drives, it might identify both 
drives as 80GB but the actual size differs. And when this type of 
drives are used on the HDD duplicator, when you start 
duplicating, you will receive a “Target Not Ready” error. To 
resolve this issue, you need to decrease the drive size of the 
source drive. To do this, navigate to: 8.Setup > 8.2Copy Size and 
use the button arrows to decrease the drive size of the source 
drive by increments of 1%.
