Can I shrink partition via Diskpart in Server 2003?

“In Windows Server 2003, my hard drive is originally allocated with one partition (Partition C). Now I want to create more partitions to save my files separately. I decide to shrink C drive to get unallocated space in Disk Management, but only find that there is no Shrink Volume Partition. Then, is it possible to use Diskpart utility to shrink partition in Windows Server 2003? If not, what should I do?”

The answer is negative

Diskpart is a command-line tool. In Windows Server 2003, you can use it to mark partition as active, assign drive letter, create partition, delete partition and so on, but not for shrinking partition, as there is no shrink command listed in Windows Server 2003 Diskpart utility. If you are running Windows Server 2008/2012 or 2016, you can use it to shrink partition through following steps:

1. Press “Windows” + “R” at the same time, input “cmd” to Run Command Prompt as Administrator.

2. Input “diskpart” to run Diskpart and run the following commands”

  • list disk

  • select disk m

  • list partition

  • select partition n

  • shrink desired=size

Notes: “m” stands for the number of the disk that contains the partition that will be shrunk; “n” is the number of the volume that you want to shrink; and the unit of size is MB.

3. After shrinking partition, you can type "exit" and hit Enter to close this window.

However, in Windows Server 2008/2012/2016, Diskpart won’t allow you to shrink partition that is not formatted with NTFS file system; when you shrink NTFS partition, there are chances that you can’t shrink partition via Diskpart and warned by error message.

The shrink failure can be caused by unmovable files (like paging file), bad clusters or something else. To shrink partition, you need to take measures accordingly. The process can be complicated and bothering.
