PARTITIONING A BASIC DISK
Primary PartitionsPrimary Partitions Extended PartitionsExtended PartitionsFour primary partitions maximum or up to three if there is an extended partition.
A basic disk can contain only one extended partition.
Can be marked as the active partition, BIOS looks for the active partition to locate boot files to start the operating system (only one active partition per hard disk).
Can’t be marked as the active partition.
Can be formatted and assigned a drive letter.
Divided into logical drives, each of which can be formatted and assigned a drive letter.

MANAGING COMPRESSION
Compression methods:
Compressed folders
NTFS compression
Chapter 3: Managing Disks and File Systems 12
COMPRESSED FOLDERS
Compatible with Zip compression programs
Can be stored on FAT volumes and removable media
Can be e-mailed
Chapter 3: Managing Disks and File Systems 13
NTFS COMPRESSION
Managed by the NTFS file system
Automatically compresses and uncompresses files
Managed via compression attributes on files and folders
Chapter 3: Managing Disks and File Systems 14
MOVING OR COPYING COMPRESSED FILES
Within an NTFS volume: Moved files retain their compression attribute. Copied files inherit the attribute of the target
folder.Between NTFS volumes: All files inherit the attribute of the target folder.To FAT or FAT32 partitions: Files are uncompressed. (FAT does not support
compression.)
Chapter 3: Managing Disks and File Systems 15
ENCRYPTING FILE SYSTEM
Based on public key cryptography
256-bit Advanced Encryption Standard (AES) encryption
Incompatible with NTFS compression
Recovery agent can recover encrypted files
Chapter 3: Managing Disks and File Systems 16
ENCRYPTING FILES
Chapter 3: Managing Disks and File Systems 17
DECRYPTING FILES
Chapter 3: Managing Disks and File Systems 18
COPYING OR MOVING ENCRYPTED FILES
Moving or copying a file into an encrypted folder encrypts it.
Moving or copying an encrypted file to an unencrypted folder does not decrypt it.
Copying or moving an encrypted file to another file system decrypts it. Moving or copying a file requires decryption
ability.
Files can be backed up in the encrypted state.
Chapter 3: Managing Disks and File Systems 19
SHARING ENCRYPTED FILES
The owner of an encrypted file can add additional users.
Works with files only.
One file at a time can be shared.
EFS is administered via the Details dialog box under Advanced Attributes for the encrypted file.

SHARING ENCRYPTED FILES (CONTINUED)
Chapter 3: Managing Disks and File Systems 21
RECOVERING ENCRYPTED FILES
The encrypted file must be recovered by the key used in the Recovery Agent.
If the recovery key certificate is lost, the file cannot be recovered.
The recovery agent’s certificate should be protected.
Chapter 3: Managing Disks and File Systems 22
DISK QUOTAS
Per-user limits on data storage.
Limits the space per volume.
Space determination based on uncompressed file size.
Configured by default to all users.
Individual users can be excepted with an individual quota.

SUMMARY
The Disk Management snap-in manages local and remote disks.
Use Disk Management to create volumes and format disks.
Basic disks contain partitions; dynamic disks use volumes.
NTFS compression and encryption are not compatible.
EFS encrypts data on NTFS volumes.
Chapter 3: Managing Disks and File Systems 27
SUMMARY (CONTINUED)
Protect the EFS recovery agent’s certificate to avoid losing files.
Use Disk Defragmenter, Chkdsk, and Disk Cleanup to optimize and repair disks.
