The Disk Management display is in two panes, with a movable horizontal divider between them. In its default arrangement, the upper pane lists each volume on your system and provides information about the volume s type, status, capacity, available free space, and so on. You can carry out commands on a volume by right-clicking in the first column of this pane (the column labeled Volume) and choosing from the shortcut menu. The lower pane provides a graphical display, in which each row is devoted to one physical storage device. In the headings at the left of each row you see the name by which the device is known to the operating system (Disk 0, Disk 1, and so on), along with the device s type, size, and online status. To the right of these headings are rectangles representing the volumes of each device. Note that, although the rectangles are of varying sizes, they are by no means drawn to scale! (In Figure 28-1, for example, the 149 GB drive K appears to be nearly four times as large as the 153 GB drive G.) To assess the size of a volume, read the numbers and note the units! Right-clicking a heading at the left in the lower pane provides a menu of commands pertinent to an entire storage device. Right-clicking a volume rectangle provides a menu of actions that can be applied to that volume.

To use the Diskpart command-line tool, start by running Cmd.exe with elevated privileges. You can do that by opening the Start menu and choosing All Programs, Accessories. In the Accessories submenu, right-click Command Prompt, choose Run As Administrator, and then reply to the UAC prompt.

Because we specify useLinks=yes, our custom tag prints an HTML table consisting of four columns with links to buy and sell individual stocks. Setting currency=USD will print all stock prices in U.S. dollars.

When you run the Diskpart command, it opens a console window and dumps you at the DISKPART> prompt. If you type help and press Enter, you see a screen that lists all available commands, like the one shown here:

Because Diskpart can do everything that the Disk Management console can do, it s invaluable for script writers or anyone who simply prefers working at a command prompt. Even if you fall into neither of those categories, you should know about Diskpart, because if you ever find yourself needing to manage hard disks from the Windows Recovery Environment (WinRE), you will have access to Diskpart but not to the Disk Management console. (WinRE is a special environment that you can use for system-

Windows also includes a second command-line tool for file-system and disk management, called Fsutil. This utility allows you to find files by security identifier (SID), change the short name of a file, and perform other esoteric tasks.

FSUtil and Diskpart are indisputably powerful, but they re not for the faint of heart or for casual experimentation. Both are intended primarily to be incorporated into scripts rather than for interactive use. Diskpart in particular is dense and cryptic, with a complex structure that requires you to list and select objects before you act on them. All but the most experienced Windows users should stick with the graphical tool whenever possible. For more details about Diskpart, see Knowledge Base article 300415, A Description of the Diskpart Command-Line Utility. Although this article dates from Windows XP days and some of the comparisons it makes between Diskpart and the Disk Management console are out of date, its information about the syntax and usage of Diskpart is still accurate.
