CREATE AN ADDITIONAL SHARE NAME FOR A FOLDER

7. On the Completion page, click Finish to create the volume.

The amount of disk space that is consumed on each disk in the striped volume must be

equal. The disk with the smallest amount of available space limits the maximum

amount of space available on a striped volume. For example, assume that you have the

following drive configuration on your computer:

■

Disk 0—No space available

■

Disk 1—2 GB available

■

Disk 2—2 GB available

■

Disk 3—1 GB available

If you attempt to create a striped volume with Disks 1, 2, and 3, the maximum volume

size that you can create is 3 GB. Because Disk 3 has only 1 GB of space available, you

are limited to using only 1 GB from each of the disks in the set. However, if you create

a striped volume using only Disks 1 and 2, the maximum volume size you can create

is 4 GB because both disks have 2 GB of available space.

Extending Volumes

Windows XP Professional supports extending volumes on both basic and dynamic

disks. You extend volumes on basic disks by using the Diskpart command-line utility.

You can extend volumes on dynamic disks by using either the Disk Management utility

or the Diskpart command-line utility.

Extending Volumes on Basic Disks You can extend primary partitions and logical

drives on basic disks if the following conditions are met:

■

The volume to be extended is formatted with the NTFS file system.

■

The volume is extended into contiguous unallocated space (adjacent free space)

that follows the existing volume (as opposed to coming before it).

■

The volume is extended on the same hard disk. Volumes on basic disks cannot be

extended to include disk space on another hard disk.

■

The volume is not the system or boot volume. The system or boot volumes cannot

be extended.

You extend volumes by running the Diskpart utility from the command line, selecting

the appropriate volume, and then executing the following command:

extend [size=n] [noerr]

See Also For further information on the use of Diskpart, refer to the section entitled “How

to Manage Disks from the Command Line by Using Diskpart” later in this chapter.

Extending Volumes on Dynamic Disks You can extend a simple volume as long as it

has been formatted with NTFS. You do this by attaching additional unallocated space

from the same disk, or from a different disk, to an existing simple volume. Disk space

that is used to extend a simple volume does not have to be contiguous. If the addi-

tional space comes from a different disk, the volume becomes a spanned volume.

Spanned volumes can contain disk space from 2 to 32 disks.

If the volume is not formatted with NTFS, you must convert the volume to NTFS before

you can extend it.
