The Need to Resize GPT Disk Partition

GPT is the abbreviation of GUID Partition Table. Compare with the Master Boot Record (MBR) disk, GPT disk have many advantages:

  • GPT disks can support the partition size larger than 2terabytes(TB), while MBR cannot.
  • GPT disks also allow up to 128 primary partitions, not just the 4 primary partitions of the MBR.
  • In addition, GPT keeps a backup of the partition table at the end of the disk.
  • GPT disks provide greater reliability due to partition table replication and cyclic redundancy check (CRC) protection.
  • In addition, GPT disks offer greater reliability. It can be used as a storage volume on all x64-based platforms.

If you are the one who are using GPT disks, it is very likely that you will encounter a situation that you need to change the size of GPT partition in your computer.

For example, when you find the distribution of your partition capacity is unreasonable: a partition has too much free space, and a partition is about to run out of space. At this time, it is important to master how to resize GPT disk partition effectively.

Tip: please keep Using Enhance Data Protecting Mode checked by default since it provides data protecting.

Step 4: Save the change.

When you see the changed result of the wanted partition on the GPT disk in the main interface, don’t exit now. Because this is just a preview, you need to click Apply to save the change.

Open the drop-down list of Take Free Space from and choose a partition to take free space from. You can choose any partition (if there’s no unallocated space) or unallocated space in the same disk without worrying if the unallocated space is continuous to take its free space.

You can decide how much space to take by dragging the sliding handle leftwards or rightwards. After that, click OK to continue. Here the demonstration chooses J partition to take free space from.

Step 3: Perform the pending operation by clicking Apply button.

How to Shrink GPT Disk Partition

To shrink a GPT disk partition. You just need to choose the Move/Resize Partition feature. The beginning and the ending are just the same as we mentioned before. So, we will not repeat the details here.
