Extending Data Volume Size
This section describes a procedure to extend a volume size using Disk Management.
IMPORTANT:
It is not possible to extend boot volume.
As it is not possible to extend mirror volume, a mirror volume is extended in the following
order: [Remove Mirror] - [Extend Volume] - [Add Mirror].
1. Remove the mirror of the volume you want to extend, and make it a simple volume.
(In the case below, the mirror of the volume (E:) is removed to extend the volume (E:).)
2. Right-click the volume to be extended and
click [Extend Volume…].
3. When the [Welcome to the Extend Volume
Wizard] dialog box of the Extend Volume
Wizard appears, click [Next].
