SYMPTOMS
When you use the Windows Server 2003 DiskPart.exe utility to extend a logical drive in an extended partition on a basic disk, you may receive the following error message after you select the volume and issue an extend command:

The volume you have selected may not be extended.

Please select another volume and try again.

Note To extend a logical drive on a basic disk, there must be unallocated free space in the extended partition that immediately follows the logical drive. If the logical drive is the last logical drive in the extended partition, there must be unallocated free space that immediately follows the extended partition.



CAUSE
This problem is a regression from Microsoft Windows Server 2003. In Windows Server 2003, the DiskPart.exe utility does not consider the free space that follows an extended partition to be usable free space.
