Dell 745N manual On Disk Device Properties, click the Policies tab

You cannot extend a volume if any of the following are true:

•The volume is formatted as FAT or FAT32.

•The volume is using software RAID (striped, mirrored, or RAID 5 volume).

•Unallocated space is not available on a dynamic disk.

You can extend simple and spanned volumes on dynamic disks onto a maximum of 32 dynamic disks. However, after a volume is extended, it cannot be mirrored or striped using software RAID. Also, no portion of a spanned volume can be deleted without deleting the entire spanned volume.

1.Right-click the simple or spanned volume you want to extend, and then click Extend Volume.

The selected volume appears in the dialog box along with its current size.

2.Enter the amount to extend the volume, and then click OK.

3.Click OK.

The volume now shows the size of the extended volume.

For more information about extending volumes, see the context-sensitive online help.

This option causes application requests to bypass disk write caching to be ignored.
