Resize mode is used to copy between Source and Target drives of different capacities. Resize copy supports the following file systems: FAT, FAT32, NTFS. If the Source is not formatted as a supported file system, then the duplicator will automatically switch to Disk copy. When duplicating in Resize mode, Target drives should all be the same capacity.

All KanguruClone HD SATA Pro duplicators support copying from a smaller Source drive to larger Target drives. Duplicators running firmware version 6.10 or later have the ability to copy from a larger Source to a smaller Target. This is extremely useful when cloning an operating system from a larger capacity HDD to a smaller capacity SSD.

In order to clone from a larger Source to a smaller Target, the following two conditions are met:

  • The Source drive must be a Windows OS drive, formatted NTFS or FAT32. Large to small resizing is not supported for Mac or Linux operating systems.
  • The total data content on the Source must be smaller than the total capacity on the Target (e.g. if the Source drive is a 500GB HDD with 100GB of used space, then the Target drive capacity must be greater than 100GB.

Other things to be aware of:

  • Encrypted partitions are not supported by Resize.
  • The exFAT file system is not supported by Resize.
  • Hidden/boot partitions are supported, as are multi-partitions as long as they are formatted NTFS or FAT32.
  • In a multi-partition situation, hidden/boot partitions are not resized. NTFS and FAT32 partitions are resized proportionally.
  • There is an option “Resize Last Partition” that can be enabled which will instruct the duplicator to resize only the last FAT32/NTFS partition on the Source drive.

Note: When using Resize Copy to duplicate a drive with multiple partitions, each partition will be expanded equally in proportion to the remaining unallocated space. If you want to resize only the last partition on the drive, you will need to enable the Resize Last Partition setup option.
