and click [Convert].
If the selected hard disk contains a system partition, you will have to restart the computer
to complete the upgrade of the hard disk. The message also states that file systems on any
of the hard disks to be upgraded will be forcedly dismounted. This means if any file
systems are in use at the time of upgrade, they will be dismounted, so that the upgrade can
continue.
5. After the system has restarted, display [Disk Management] again and set the hard disks
for creating mirror volume.
IMPORTANT:
When the hard disk status is "Not Initialized", right-click that hard disk and initialize it.
If "Foreign" is displayed, perform "Convert to Basic Disk" and then perform "Convert
to Dynamic Disk...".
