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.
