Change Drive Letters in Windows XP

When you add drives to your computer, such as an extra hard drive, a CD drive, or a
storage device that corresponds to a drive, Windows automatically assigns letters to the
drives. However, this assignment might not suit your system; for example, you might have
mapped a network drive to the same letter that Windows assigns to a new drive.
· Right-click My Computer, and then click Manage.
· Under Computer Management, click Disk Management. In the right pane, you'll see your
drives listed. CD-ROM drives are listed at the bottom of the pane.
· Right-click the drive or device you want to change, and then click Change Drive
Letter and Paths.
· Click Change, click Assign the following drive letter, click the drive letter you
want to assign, and then click OK.
You will not be able to change the boot or system drive letter in this manner. Many
MS-DOS-based and Windows-based programs make references to a specific drive letter (for
example, environment variables). If you modify the drive letter, these programs may not
function correctly.
