Besides, you can manage both Basic disks and Dynamic disks. If an NTFS volume is on a hardware RAID 5 container to which free space can be added, you can extend the NTFS Volume with Diskpart while the disk remains a Basic disk. Diskpart is actually the underlying utility which augments the Disk Administrator graphical user interface and enables a superset of the operations which are supported by the Disk Management snap-in. However, you must list firstly and then select the object to give it focus before you use Diskpart commands on a disk, partition, or volume. Only when an object is focused, can Diskpart commands work on that object.

To extend a partition on server with Diskpart, you have to insure that:

  • For Basic volumes, the unallocated space for the extension must be the right contiguous space on the same disk.
  • For Dynamic Volumes, the unallocated space can be any empty room on any Dynamic disk on the system.
  • The volume you are going to extend must be formatted with the NTFS file system.
  • You cannot extend the partition on which the system page file is located. Move the page file to another partition which you do not want to extend.
  • Only data volumes extension is supported.

  • Extension of boot, system, and/or page files volumes is prohibited by Diskpart unless Diskpart is run from a command line by bootable CD.
  • Extend data partition is also impossible if there is no contiguous unallocated space behind it and it is not NTFS file system.
  • It is very difficult for many users to use command line.
  • Data loss may be caused by inputting incorrect orders and the orders cannot be repealed.
  • It stops the Server from running for a long time.
