Unable to shrink volume or expand volume in Server 2016? Try 3rd party tool Partition Resizer that can help resize any drive in Windows Server 2016 when disk management or server manager failed.

Use the Diskpart Command Prompt to Expand Partition Size.

Here is a step-by-step guide to resize a partition using Diskpart in Windows Server 2016:

Step1: Open Command Prompt as administrator: To do this, click the Start button, type "cmd" in the search box, right-click Command Prompt and then select Run as administrator.

Step2: Start Diskpart: Type "diskpart" in the Command Prompt and press Enter.

Step3: List the disks: Type "list disk" and press Enter. This will display the list of disks connected to your system.

Step4: Select the disk: Type "select disk X" where X is the number of the disk you want to resize. For example, if you want to resize disk 1, type "select disk 1" and press Enter.

Step5: List the partitions: Type "list partition" and press Enter. This will display the list of partitions on the selected disk.

Step6: Select the partition: Type "select partition X" where X is the number of the partition you want to resize. For example, if you want to resize partition 1, type "select partition 1" and press Enter.

  • Shrink the partition: To shrink the partition, type "shrink desired=size" where "size" is the amount of space in MB that you want to free up. For example, if you want to free up 100 MB, type "shrink desired=100". (Shrink volume option is not available for diskpart on FAT32 drives)
  • Create a new partition: After shrinking the partition, you can create a new partition using the newly freed up space. To do this, type "create partition primary size=size" where "size" is the size of the new partition in MB.
  • Assign a drive letter: Finally, assign a drive letter to the new partition using the following command: "assign letter=X" where X is the drive letter you want to assign. For example, if you want to assign drive letter F, type "assign letter=F".

Note: Before you start resizing partitions, it's a good idea to backup your data as resizing partitions can result in data loss.

Note: Extending volumes using Diskpart is not easy since it requires the following conditions:

  • The target drive is NTFS, not fat32
  • There is unallocated space on the right side of the target volume
  • The disk is not dynamic

No such conditions? Try Partition Resizer Server that can do the job when Diskpart failed.
