INSTALLING AND MANAGING STORAGE DEVICES IN WINDOWS XP
Explain the use of basic and dynamic disks
Manage hard disks by using the Disk Management utility
Use the hard disk maintenance tools that are available in Microsoft Windows XP
Monitor and troubleshoot CD-ROM and DVD-ROM devices
Troubleshoot problems with other removable devices
Chapter 8: Installing and Managing Storage Devices in Windows XP 3
BASIC AND DYNAMIC DISKS
Basic disks have the following features: Traditional type of volume - used by default
Available in Windows XP Professional and Home Editions
Limited number of partitions
Chapter 8: Installing and Managing Storage Devices in Windows XP 4
BASIC AND DYNAMIC DISKS (CONTINUED)
Dynamic disks have the following features: Available in Windows XP Professional Edition
only
No limit on number of volumes
Can extend dynamic volumes
Not available on portable computers
Chapter 8: Installing and Managing Storage Devices in Windows XP 5
BASIC DISKS: PRIMARY PARTITION
Up to four primary partitions can be created on a basic disk
A primary partition is always formatted as a single volume
Computers can boot from primary partitions
Chapter 8: Installing and Managing Storage Devices in Windows XP 6
BASIC DISKS: EXTENDED AND LOGICAL PARTITIONS
Only one extended partition can be created on a basic disk
The extended partition can be divided into many volumes
An extended partition must have at least one logical drive created within it in order to hold data
A computer cannot boot from an extended partition
Chapter 8: Installing and Managing Storage Devices in Windows XP 7
DYNAMIC DISK ADVANTAGES
When you partition a dynamic disk, all areas created are called volumes
There is no limit to the number of volumes that can be created on a dynamic disk
Configuration information is stored entirely on the disk
With multiple dynamic disks, information is replicated to all disks for redundancy
Chapter 8: Installing and Managing Storage Devices in Windows XP 8
DYNAMIC DISK ADVANTAGES (CONTINUED)
Volumes can be extended using contiguous or noncontiguous disk space
Volumes can be made up of disk space on more than one disk
Fault-tolerant volumes can be created on operating systems that support them
Chapter 8: Installing and Managing Storage Devices in Windows XP 9
DYNAMIC DISK VOLUME TYPES
Simple volumes – contains disk space from a single disk and can be extended if necessary
Spanned volumes – contain space from 2 or more disks. 2x40GB drives would look like 1 80gb drive. No fault tolerance.
Striped volumes – contains space from 2 or more disks. When windows writes data to a striped volume it divides it into 64KB chunks and splits them among the disks. Referred to as RAID 0. This is used for performance.

USING DISK MANAGEMENT

CREATING PARTITIONS ON BASIC DISKS
Primary partition – Page 269 gives you detailed instruction on how to do this. We will also be doing this in our labs.
Extended partition- Page 271. This is in the labs also.

BASIC DISKS: CREATING A LOGICAL DRIVE
Chapter 8: Installing and Managing Storage Devices in Windows XP 13
FORMATTING VOLUMES
In Windows XP, you can format basic and dynamic disks in many ways: In Disk Management, use the wizard when the
volume is being created
In Disk Management, right-click an existing volume and select Format from the Action menu
In Windows Explorer, right-click the drive letter and select Format from the Action menu
At a command prompt, use Format.exe with the appropriate switches

FORMATTING OPTIONS
Chapter 8: Installing and Managing Storage Devices in Windows XP 15
DRIVE LETTERS AND PATHS
A volume cannot be assigned multiple drive letters
No two volumes on the same computer can be assigned the same drive letter
A volume can be mounted into multiple paths simultaneously
A drive letter can simultaneously reference a mounted volume
A volume can exist without a drive letter or mount path assigned, but it cannot be accessible by applications

Chapter 8: Installing and Managing Storage Devices in Windows XP 17
UPGRADING A BASIC DISK TO A DYNAMIC DISK
Chapter 8: Installing and Managing Storage Devices in Windows XP 18
NO UPGRADE TO DYNAMIC DISK OPTION —WHY?
The disk has already been upgraded to dynamic
You have right-clicked a volume instead of the disk
The disk is in a portable computer
1 MB of space is not available at the end of the disk to hold the dynamic disk database
The disk is a removable disk
The sector size on the disk is larger than 512 bytes
Chapter 8: Installing and Managing Storage Devices in Windows XP 19
REVERTING FROM A DYNAMIC DISK TO A BASIC DISK
Back up all files and folders on the entire disk
Delete all the volumes from the disk
Right-click the dynamic disk, and select Revert To Basic Disk from the context menu
Follow the on-screen instructions
Create an appropriate partition scheme, and format the newly created drives
Restore data as necessary
Chapter 8: Installing and Managing Storage Devices in Windows XP 20
VOLUMES ON DYNAMIC DISKS
A simple volume contains space on a single disk
Striped volumes involve sections of multiple disks
Chapter 8: Installing and Managing Storage Devices in Windows XP 21
EXTENDING VOLUMES ON BASIC DISKS
Conditions for extending primary partitions and logical drives on basic disks: The volume to be extended is formatted with
NTFS
The volume is extended into contiguous, unallocated space
The volume is extended on the same hard disk
The volume is not the system or boot volume

EXTENDING VOLUMES ON DYNAMIC DISKS
Chapter 8: Installing and Managing Storage Devices in Windows XP 23
IMPORTING FOREIGN DISKS
When you move a dynamic disk from one computer to another: Windows displays it as a foreign disk
You must import the disk, which merges the disk’s information into the dynamic disk database on the new computer

Before you add a large number of files
After installing application programs
After installing Windows XP

Unrecognized
No Media

CHAPTER SUMMARY
Windows XP Professional Edition supports two types of disk storage: basic disks and dynamic disks. Windows XP Home Edition supports only basic disks. Portable computers also support only basic disks.
Use Disk Management to configure, manage, and monitor hard disks and volumes.
You must format a volume before it can accept data, and you can format each volume with only a single file system.
Chapter 8: Installing and Managing Storage Devices in Windows XP 37
CHAPTER SUMMARY (CONTINUED)
Volumes are usually assigned drive letters, such as C or D, which you use to reference the volume from within the operating system and through applications.
Mounted volumes extend the perceived available space on an existing volume without extending the volume’s size.
You can use additional disk utilities such as Disk Defragmenter and Chkdsk to ensure optimal disk performance.
