Preparations before cloning disk:
  • Make sure that the capacity of the target disk is equal to or larger than the source disk. The extra space of the target disk will become unallocated space, which cannot be recognized by the system, so you can create a new partition with the partition management function.
  • The data on the target disk will be cleared, so if you have important data on it, please make sure to make a backup first.
  • The data on the source disk will be cloned to the target disk intact, and the data on the source disk will not be changed or lost during the cloning process.

Clone Hard Disk to SSD/HDD:

  • Step 1:Connect an external disk to your computer after downloading and installing 4DDiG Partition Manager on your computer. Then launch the application, select “Clone Disk”.

    select Clone Disk
  • Step 2:Select a target disk to receive cloned data from the source disk and then click on the Continue button. (The target disk defaults to the disk you connect to the computer).

    Select a target disk
  • Step 3:Please note that cloning will overwrite all data on the target disk, so after you confirm that everything is correct, click on the Sure button.

    click on the Sure button
  • Step 4:Then, you will see a preview interface showing the effect of the cloned disk. After confirming that the preview is correct, click on the Start button to start the cloning operation.

    click on the Start button
  • Step 5:Wait for the disk cloning to complete. The speed of cloning depends on the size of the source disk. Please wait patiently and do not perform other operations or interrupt the current operation.

    wait

    Now you have successfully cloned the data from the source disk to the target disk.

    successfully cloned the data

Clone Partition:

  • Step 3:Then, select a target partition to receive cloned data from the source partition. After you make sure that your selection is correct, click on the Continue button.

    click on the Continue button
  • Step 4:Please note that cloning will overwrite all data on the target partition, so after you confirm that everything is correct, click on the Sure button.

    click on the Sure button
  • Step 5:Then, you will see a preview interface showing the effect of the cloned partition on the target disk. After confirming that the preview is correct, click on the Start button to start the cloning operation.

    wait
  • Step 6:Wait for the partition cloning to complete. The speed of cloning depends on the size of the source partition.

Extend/Shrink Partition

4DDiG Partition Manager allows you to extend a partition to make it bigger or shrink a partition to make it smaller in size. When your disk partition runs out of disk space, you can expand the storage of the partition by taking free space from unallocated space in the same disk or shrinking any other existing partitions.

Note

The Extend/Shrink feature will be unavailable when there are more than 4 partitions on your disk. Besides, you cannot extend or shrink a partition with free or unallocated space in another separated hard disk.

Merge Partitions

Merging partitions refers to combining two partitions of one hard drive into a single larger one or combining unallocated space with an existing partition to expand the available space on a partition. Partition merging is quite necessary when you have multiple partitions on your hard drive and you want to reduce the redundant ones for better management, or when one of your partitions is getting full but other partitions are nearly empty.

Format Partition

Formatting a partition is the process of deleting all data on a chosen partition and installing a file system to prepare available space for the operating system. There are many situations when you need to format a partition:

  • When you want to delete all data on a partition without deleting the partition, you can format it for rearrangement.
  • A partition that is newly created should be formatted before it can be used to store data.
  • When the file system of a partition is not supported or gets damaged or corrupted, you can format the partition with a new file system like NTFS and exFAT.
