MANAGING DISKS AND FILE SYSTEMS

1. Chapter 3 MANAGING DISKS AND FILE SYSTEMS

2. Chapter 3: Managing Disks and File Systems OVERVIEW • Monitor and configure disks • Monitor, configure, and troubleshoot volumes • Monitor and configure removable media, such as tape devices • Install, configure, and manage DVD and CD-ROM devices • Configure NTFS, FAT32, and FAT file systems • Use disk optimization utilities: Disk Defragmenter, Chkdsk, and Disk Cleanup

3. Chapter 3: Managing Disks and File Systems DISK MANAGEMENT • Types of storage • Setting up hard disks • Adding new disks • Managing disks on remote systems

4. Chapter 3: Managing Disks and File Systems BASIC VS. DYNAMIC STORAGE

5. Chapter 3: Managing Disks and File Systems PARTITIONING A BASIC DISK

6. Chapter 3: Managing Disks and File Systems VOLUMES ON A DYNAMIC DISK • Simple • Spanned • Striped

7. Chapter 3: Managing Disks and File Systems UPGRADING BASIC DISKS TO DYNAMIC DISKS

8. Chapter 3: Managing Disks and File Systems MANAGING STORAGE ON REMOTE SYSTEMS

9. Chapter 3: Managing Disks and File Systems REMOVABLE STORAGE MANAGEMENT

10. Chapter 3: Managing Disks and File Systems MEDIA POOLS • Free • Import • Unrecognized • Application-specific • http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_rsmconcepts_3_2.mspx?mfr=true

11. Chapter 3: Managing Disks and File Systems MANAGING COMPRESSION Compression methods: • Compressed folders • NTFS compression

12. Chapter 3: Managing Disks and File Systems COMPRESSED FOLDERS • Compatible with Zip compression programs • Can be stored on FAT volumes and removable media • Can be e-mailed

13. Chapter 3: Managing Disks and File Systems NTFS COMPRESSION • Managed by the NTFS file system • Automatically compresses and uncompresses files • Managed via compression attributes on files and folders

14. Chapter 3: Managing Disks and File Systems 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.)

15. Chapter 3: Managing Disks and File Systems 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

16. Chapter 3: Managing Disks and File Systems ENCRYPTING FILES

17. Chapter 3: Managing Disks and File Systems DECRYPTING FILES

18. Chapter 3: Managing Disks and File Systems 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.

19. Chapter 3: Managing Disks and File Systems 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.

20. Chapter 3: Managing Disks and File Systems SHARING ENCRYPTED FILES (CONTINUED)

21. Chapter 3: Managing Disks and File Systems 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.

22. Chapter 3: Managing Disks and File Systems 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.

23. Chapter 3: Managing Disks and File Systems DISK DEFRAGMENTER

24. Chapter 3: Managing Disks and File Systems CHKDSK

25. Chapter 3: Managing Disks and File Systems DISK CLEANUP

26. Chapter 3: Managing Disks and File Systems 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.

27. Chapter 3: Managing Disks and File Systems 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.
