To run Disk Management, do any of the following:

> At a command prompt, type diskmgmt.msc.

> Right-click Computer and choose Manage. The Computer Management console appears. In the console tree (the left pane), select Disk Management.

In Control Panel, choose System and Maintenance. Then, under the heading Administrative Tools, choose Create And Format Hard Disk Partitions.

Whatever route you take, you’ll pass a UAC prompt along the way. Managing disks requires an administrative token. Figure 28-1 illustrates the Disk Management console.

As you can see, Disk Management provides a wealth of information about physical disks and the volumes, partitions, and logical drives in place on those disks. You can use this utility to perform the following disk-related tasks:

~ Check the size, file system, status, and other properties of disks and volumes

~ Create, format, and delete partitions, logical drives, and dynamic volumes

~ Assign drive letters to hard disk volumes, removable disk drives, and optical

~ Create mounted drives

~ Convert basic disks to dynamic disks, and vice versa

~ Create spanned and striped volumes

~ Extend or shrink partitions

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.
