You cannot extend a volume if any of the following are true:
l
The volume is formatted as FAT or FAT32.
l
The volume is using software RAID (striped, mirrored, or RAID 5 volume).
l
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.

NOTICE:
Enabling write cache, which causes data to be cached by the drive before it is written to disk, may lead to data loss if the system loses power.
To prevent data loss, Dell recommends using a UPS with your system if write cache is enabled.
