Dynamic disk is an advantage disk format than basic disk; it has functions of create the mirrored volume ,spanned volume, simple volume, striped volume and RAID5 volume. With these predominant features it ensures of protecting data and enhancing read/write performance with striped volume and fault-tolerant.

Now we introduce emphasis two dynamic volumes with fault tolerance– mirrored volume (provide data redundancy) and RAID5 (Redundant Array of Inexpensive Disks). Mirrored volume—nothing is forbid to written into the two disks at the same time; once disks fail or corrupt, you also have a backup to the disk problems. RAID5—combined by striped volume and mirrored volume, means absorbing their superiority, with data run fast and fault-tolerant.

In the event that you are acquainted with the procedure of the methods to extend shrink and resize the dynamic volume already, you may sill meet with many problems to finish such works. Though not all the windows QS are able to resize and extend the dynamic volumes, we can do it in Windows7/Vista/2008.

 We introduce two ways about resizing the mirrored volume here. The reason why we choose these two ways about resizing the mirrored volume is very simple—two typical ways.

 We choose two simple typical ways to introduce about resizing the mirrored volume here.

 1. Particular way

• Break the mirror before resize it until completed.
• Again add mirror for the volume.

2. Another way (different from the particular way totally).

• Use the Dynamic Disk Converter to convert dynamic disk to basic disk.
• Use the Partition Assistant to resize the basic partition.
• Again convert the basic disk to dynamic disk and add mirror to re-make it become mirrored volume.

Read the procedures above, you learn to operate. You have already found mirrored volumes not be resized directly, to extend, shrink and resize it you have to experience so many complicated.

• It is possible to resize the simple volume and spanned volume, but to the striped volume and RAID5 volume, that impossible (except the Windows7/Vista/2008, that is mentioned above).
• It is not available to shrink dynamic volume through the Windows built-in disk manager under the Windows XP/2000/2003. For simple volumes, it can be resized only by using the way of spanned volume when it is too low disk space or we want to increase more free space.

Based on the above introduction, it seems that Windows7/Vista/2008 provided the better disk management services to users than XP/2000/2003. Even without the third-party partition software help, you still could extend, shrink and resize dynamic volume on hard drives.

Over saw the introduction above, you got clear about that Windows7/Vista/2008 provided the better disk management services to users than its previous OS XP/2000/2003. You can also extend, shrink and resize dynamic volume on hard drives with no third-party partition manager.
