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
Fall 2011 11Nassau Community College ITE153 – Operating Systems
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

Compression
Fall 2011 34Nassau Community College ITE153 – Operating Systems
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

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
