Introduction of Windows Diskpart Command

In the field of computing, Windows Diskpart Command is a partition utility presented by command codes, and it has been employed in the versions of Windows NT operating systems since Windows 2000. There are many command prompts to carry out corresponding partition operations. For example, “list disk” “select disk x” “delete partition” “extend” “exit”, etc. Thus the Diskpart Command can play a very significant role in disk management.

Diskpart Helps to Increase Partition Size

As a Windows built-in tool, Diskpart Command can resolve many common disk problems. However, there are several limitations when completing the task of “Extend Volume”.

  • The Diskpart Command in operating systems of Windows 2003 and those before can not extend the system.
  • In addition, it can only increase data volume when there is an adjacent unallocated space behind the target drive.
  • If there is no unallocated space, the only way to resolve this problem is to delete the adjacent drive to get an unallocated space.

Then, here come the steps of increasing system partition size with Diskpart Command in Windows OS after Windows 2003. There are two situations.

Tips: Input “Diskpart” in the Search Bar, and click “OK” to enter the Diskpart utility.

Situation 1: There is a contiguous unallocated space behind system drive.

  • Step 1: Input “list disk” command, and press “Enter”. Then, all of the disks will be listed.
  • Step 2: Input “select disk x” command to select the target disk, and then press “Enter”.
  • Step 3: Input “list partition” and press “Enter”. Then, all the partitions will be listed.
  • Step 4: Select the partition needs to be extended by inputting “select partition x” and pressing “Enter”.
  • Step 5: Input “Extend” command, and press “Enter”.
  • Step 6: Input “Exit” to leave the Diskpart window.

Situation 2: There is no unallocated space right behind system volume.

In this case, you have to delete the adjacent drive to get an unallocated space by inputting the commands: “list disk”-> “select disk x”-> “list partition”-> “select partition y”-> “delete partition”-> “select partition x”-> “extend”-> “exit”.

Notes: Disk x is the disk on which there is the target system drive that needs to be extended.

Partition x is the system drive needs to be extended.

Partition y is the volume right behind the target system partition.

If there are any disk problem that can not be handled by Windows snap-in Diskpart Command, a powerful tool, AOMEI Partition Assistant will be strongly recommended. The picture below is its main interface.

With the clear prompts, either the system or date volume can be increased easily and safely. Therefore, if you are worrying about this problem, just try out it immediately.
