The hard drive duplicator copies the exact partition from the source drive to the target drive. Since it is required that you use a target drive that is equal or larger in size than the source drive a portion of the target drive appears as free space. You can append free space to the live partition on the target drive so that the full size of the drive can be utilized.
Note: A partition cannot be extended on an operating system drive that is in use. You must extend the partition when it not being used by the operating system, and ideally when it is still connected to the duplicator.
Note: Do not extend a System Reserved partition. Only extend the primary partition, which is typically the largest in size and formatted with NTFS or FAT32.

The primary partition on the drive now uses the entire drive area.
