In addition to the tools for managing disks in WS2003, you can also
use the diskpart and defrag
commands to manage and defragment volumes and partitions from the
command line or to schedule disk-management tasks.

Disk Management

Disk Management, a snap-in
that
is part of Computer Management, is the primary tool for managing
disks on local or remote computers. It can be used to add and remove
disks, create and manage partitions and volumes, change drive
letters, mount volumes, create fault-tolerant volumes, configure disk
quotas, and so on. The way Disk Management displays information can
be changed using the View menu as follows.

View Top

Lets you display one of three views in the top portion of the
righthand pane

Disk List

Provides information about the physical disks (hard drives, CD-ROM
drives, and so on) in your system

Volume List

Provides information about the partitions, volumes, and logical
drives on your hard disks

Graphical View

Shows information about the partitions, volumes, and logical drives
on your disks using color-coded regions

View Bottom

Lets you do the same and also lets you hide the bottom pane entirely,
which is useful if you have a lot of disks or volumes on your system

View Settings

Lets you change the color coding and horizontal scaling of the
regions in Graphical view

View All Drive Paths

Displays any drive paths (volume mount points) on a disk system that
is configured for dynamic storage

Disk Defragmenter

This snap-in, also part

of
Computer Management, lets you manually defragment disks on the local
computer to improve performance. Fragmentation is generally less of
an issue with NTFS volumes than with FAT or FAT32 volumes since NTFS
usually needs fewer disk accesses than FAT to locate all the
fragments of a file. However, a significant performance improvement
in disk access can be achieved by regularly defragmenting all volumes
and partitions, including NTFS volumes and partitions, on a WS2003
computer. Disk Defragmenter achieves this performance gain by:

• Consolidating fragments of files and folders by moving them to one
  location so that each file and folder occupies a contiguous segment
  of space on the volume. Disk Defragmenter consolidates all fragments
  of each file into a single contiguous block of space, but different
  files may occupy different blocks of contiguous space after
  defragmentation. In other words, Disk Defragmenter
  doesn't cause all files on the volume to be grouped
  into a single contiguous region of space on the disk.

• Consolidating free space to make it less likely that new files become
  fragmented. Disk Defragmenter typically doesn't
  attempt to completely consolidate all free space on the volume,
  however, since this generally provides little improvement in
  performance.

You can run Disk Defragmenter in two modes:

Analysis

Determines the amount of file fragmentation present and indicates
whether defragmenting the disk is worthwhile. After analyzing a
volume, the Analysis Display graphic box displays the
volume's initial state of fragmentation using the
color-coded legend at the bottom of the screen.

Defragmentation

Defragments the disk and displays the progress in the Defragmentation
Display graphic box.

You can pause or stop the analysis or defragmentation process at any
time. Both the analysis and defragmentation processes produce reports
you can view, save, and print. Note that only the report gives an
accurate view of the defragmentation state of the volume; the
graphical displays are only approximate since they
can't resolve individual clusters into colored
regions due to screen-resolution limits.

Although it is possible to use your computer while a disk is being defragmented, this is generally not a good idea as the system will be slow to respond due to the overhead of the defragmentation process. Making changes to files during defragmentation can also considerably lengthen the defragmentation process. Instead, pause or stop defragmentation, perform the work you have to do, and then restart defragmentation.

Disk Cleanup

This utility can be used to
delete unnecessary files from your disks,
including temporary files, cached web pages, downloaded ActiveX
controls, and so on. It can also be used to empty the Recycle Bin,
compress files you haven't accessed for some time,
and uninstall optional Windows components or applications you no
longer need. The net result is more free space on your disk. To start
Disk Cleanup, use one of the following methods:

Start Programs Accessories System
Disk Cleanup

Windows Explorer or My Computer right-click on a drive
Properties General Disk Cleanup

Computer Management Storage Disk Management
right-click on a drive Properties
General Disk Cleanup

Command prompt cleanmgr

Error Checking

This option runs the
Check Disk (chkdisk)
command to scan a disk for possible damage. If you are encountering
unknown data errors when reading files, you can try running this
utility by:

Windows Explorer or My Computer right-click on a drive
Properties Tools Error Checking

Computer Management Storage Disk Management
right-click on a drive Properties
Tools Error Checking

Command prompt chkdsk
