Disk Clone retains the information and structure (including partition) of the backed up drive. During the restore process, it ensures that the image drive is recovered as is, and hence it makes the space on the destination drive to match its own size.
For example, if you restore a 100 GB drive / system image file to a 500 GB hard drive partition, your partition will shrink to a 100 GB drive after the recovery. To handle this storage shrink, create the destination partition the same as that of drive / system image file size that you wish to recover. You may refer to the below steps for re-partitioning.
Steps to re-partition the destination drive, before image file restore:
You can now restore your image file to the newly created partition.
