Organizing a Dynamic Disk

Striped volume

Simple volume

Spanned volume

Contains disk space from a single disk

Data is written alternately and evenly to two or more disks

Includes disk space from two or more disks, filling the first disk, then the second, and so on


Creating a Volume

A simple volume resides on a single dynamic disk

To create a spanned or striped volume, you must have two or more dynamic disks

You cannot use the new volume wizard to format a volume as FAT or FAT32


Moving Dynamic Disks

When moving a dynamic disk, select import foreign disk to update the dynamic database on the newly added disk

When moving multidisk volumes, move all disks in the volume at the same time

Overview

• Working with File Systems• Managing Data Compression• Securing Data by Using EFS


Working with File Systems

• Using FAT or FAT32• Using NTFS• Selecting a File System• Converting File Systems


Using FAT or FAT32

FAT or FAT32:Works well on small disks with simple

folder structuresSupports dual-boot configurationsWindows XP

Windows 98

FAT/FAT32FAT/FAT32FAT/FAT32FAT/FAT32


Using NTFS

NTFS provides:• Improved reliability by identifying and

not using bad sectors• Enhanced security by using EFS and file

permissions• Improved management of storage

growth• Support for large volume sizes


Selecting a File System

When selecting a file system, determine:• How the computer is used • The number and size of locally installed

hard disks• Security considerations• The need for advanced file system

features

Managing Data Compression

• Defining Compressed Files and Folders• Compressing Files and Folders• Copying and Moving Compressed Files

and Folders• Best Practices for Managing Data

Compression


Defining Compressed Files and Folders

• NTFS files and folders have a compression state

• When accessed, files are automatically uncompressed

• Space allocation is based on uncompressed file size

• Compressed files and folders can be designated by color

Best Practices for Managing Data Compression

Determine which file types to compress Determine which file types to compress

Avoid compressing system or executable filesAvoid compressing system or executable files

Compress static data rather than data that changes frequentlyCompress static data rather than data that changes frequently

Use different display colors for compressed files and foldersUse different display colors for compressed files and folders

Securing Data by Using EFS

• Introduction to EFS• Encrypting a Folder or File• Adding Authorized Users• Decrypting a Folder or File• Recovering an Encrypted Folder or File• Best Practices for Implementing EFS


Introduction to EFS

Is transparent to users and applicationsIs accessible only to authorized usersEnables specification of a data recovery

agentEncrypts files locally or across the

networkEnables encrypted files and folders to be

designated by color

~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~


Encrypting a Folder or File

Encrypt contents to secure data

When file is saved, it is encrypted by using file encryption keys

If designated, the recovery agent’s file encryption key is stored in the Data Recovery Field in the file header

The user’s file encryption key is stored in the Data Decryption Field

Decrypting a Folder or File

File content appears on the screen in plaintext

Your private key is applied to the DDF

EFS automatically detects encryption and locates user certificate and associated private key
