How can I use DiskPart to extend a volume?

A. You can use the DiskPart utility from the Windows 2000 Server Resource Kit or the Win2K Professional Resource kit to extend an existing volume by performing the following steps:

  1. Download the DiskPart utility from the Microsoft website, then install it on your computer.
  2. Go to Start, Run, then type
    to start a command-line session.
  3. Type
    to start a DiskPart session.
  4. Type
    list volume
    to list the current volumes. The list will look like
       Volume ### Ltr Label Fs Type       Size  Status   Info
       ---------- --- ------------------- ----- -------- -------
       Volume 0   C   NTFS Partition      10 GB Healthy  System
       Volume 1   D   Data NTFS Partition  9 GB Healthy  Pagefile 
  5. Type
    select volume <volume number>
    to select the volume you want to extend.
  6. Type
    to extend the selected volume. If you don't pass any parameters, DiskPart will use all unpartitioned space on the current disk. Alternatively, you can type
    extent size=<size in MB> disk=<disk number>
    to set a size and disk to use for the extension.
  7. Type
    when you're finished.

You can extend only volumes created on a dynamic disk, not volumes created on a basic disk that you've upgraded. If you try to extend volumes created on a basic disk, you'll receive the error "DiskPart failed to extend the volume. Please make sure the volume is valid for extending."
