This chapter introduces data storage management on different types of volumes. You will learn about the different types of disk devices and volumes, as well as how to manage and troubleshoot them in Windows XP Professional. You will learn about compression, which allows you to store more data on a disk, and you will learn about disk quotas, which allow you to control how much space a user can use on a disk. You will learn how you can increase the security of files and folders on your computer by using the Microsoft Encrypting File System (EFS). You will also learn about defragmenting a disk, which allows your system to access and save files and folders more efficiently. Lessons in this :

Lesson 1: Managing and Troubleshooting Disks and Volumes
Hard disks are fixed storage devices that are connected to a computer by Integrated Device Electronics (IDE) or Small Computer System Interface (SCSI) controllers. Portable hard disks are also available, and they can be connected with universal serial bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 (also known as FireWire) interfaces. Windows typically treats portable hard disks, CD-ROM drives, and DVDs as removable storage devices. This lesson focuses on configuring and troubleshooting hard disks in Windows XP. You should also be able to use the tools that Windows XP provides for managing, maintaining, and troubleshooting hard disks.
After this lesson, you will be able to
Explain the use of basic and dynamic disks. Manage hard disks by using the Disk Management tool. Manage hard disks on a remote computer in Computer Management. Manage disks from the command line by using the Diskpart command. Troubleshoot disks and volumes. Work with removable media.
Estimated lesson time: 70 minutes
Overview of Basic and Dynamic Disks
Windows XP Professional supports two types of hard disk storage on desktop computers: basic disks and dynamic disks. (You cannot use dynamic disks on portable computers.)
Basic Disks
Basic disks are the traditional type of storage that is available in earlier versions of Microsoft Windows. Basic disks are also the default storage type in Windows XP, so all hard disks begin as basic disks. Windows XP recognizes all disks as basic by default, including all new installations and upgrades from previous versions of Windows. To use a dynamic disk, you must convert a basic disk to a dynamic disk. On a basic disk, you must create one or more partitions (also called basic volumes). Partitions were covered in detail in 2, Installing Windows XP Professional, but a brief review is in order. You must configure a basic disk with at least one partition. In fact, most computers that you will encounter have a single hard disk with one partition that takes up all the phys-
