Disk Formatting
Disk Formatting
• Two formatting procedures required before you can write user data to a disk – Physical or low-level formatting – Logical or high-level formatting
Steps for storing data
•
1. Low-Level Formatting – Manufacturer
Low-level formatting is the process of outlining the positions of the tracks and sectors on the hard disk, and writing the control structures that define where the tracks and sectors are .
This is often called a " true where the data is stored on the disk .
" formatting operation, because it really creates the physical format that defines
Low-Level Formatting
• This is the basic setup of the disk layout • Dividing the disks tracks into a specific amount of sectors • Creating header & trailer information • Lays basic ground work of the formatting
High-Level Formatting
• High level formatting is the process of writing the file system structures on the disk that let the disk be used for storing programs and data .
• OS writes the structures necessary for managing files & data on the disk
Partitioning
• Creating a partition on a hard drive enables it to support separate file systems, each in its own partition • Each file system can then use its own method to allocate file space in logical units called clusters or allocation units
Common file systems used by OS
• FAT 16 (File Allocation table 16-bit) • FAT 32 (File Allocation Table 32-bit) • NTFS (NT File System)
Data structures
• Enable OS to: • Manage the space on the disk • Keep track of files • Manage defective areas so they don’t cause problems
High-level formatting
• Creating of the “table of contents” • Low-level formatting is the physical formatting of the drive
File systems
• • In this section, it is important to differentiate between the
FAT file system
and
the file allocation table (FAT)
.
• FAT is the name of the file system used by DOS operating systems (DOS and Windows 95, as well as Windows NT and OS/2 which support it).

Master Boot Record or MBR
• The
boot sector
(called the
Master Boot Record
or
MBR
) is the first sector of a hard drive (cylinder 0, head 0, sector 1), it contains the
main partition table
and the code, called the
boot loader
, which, when loaded into memory, will allow the system to boot up.
The Expanding Windows Family
Windows 2000 series Windows 9x Windows XP
Microsoft Windows 98
• Introduced in 1998 • The first version of Windows to take advantage of Plug and Play technology ( H/W meeting the plug and play requirements is automatically detected and configured by the O.S after installation) • Introduced a new generation of support tools (maintenance wizard that allows users to schedule automatic execution of disk defragmentation and other routine) • Closely integrated the browser for the Internet with the operating system (OS)
Microsoft Windows Millennium Edition (Me)
• Introduced in the third quarter of 2000 • Designed for home and general office use • It continuous the trend in windows development toward improved ease of use, ease of maintenance, and support for the newest PC H/W.
• Closely linked to the Internet • Includes several new features and improvements , • Hardware requirements geared to the typical home PC • Can be installed by the average end user.
Microsoft Windows NT
• OS designed for power users ( using computers for scientific and technical applications) • Has a completely different OS than Windows 9
x
( faster performance, advanced security, ability to operate with a number of different processor families).
• Available in Workstation and several Server editions • Microsoft Windows NT 3.1 released in 1993 and Microsoft Windows NT 3.51 in 1995 • Microsoft Windows NT 4.0
released in 1996; incorporated an interface very similar to that of Windows 95
Microsoft Windows 2000
• successor to Windows NT • Windows 2000 combines the best of windows 98 and windows NT.
• It offers and extends the multiprocessor support , advanced security and administration tools, NTFS file system.
• Family of four products: – Windows 2000 Professional – Windows 2000 Server – Windows 2000 Advanced Server – Windows 2000 Datacenter Server

System Requirements Compared
System Configuration Considerations
• The amount of random access memory (RAM) and processing power needed depend on the system usage.
• A graphics adapter and RAM improves the display performance.
• You need sufficient hard disk drive space for the OS, applications, and upgrades.
Plan the Installation
• Windows 98 and Windows 2000 have automated setup programs.
• You should follow a checklist during setup for optimal results.
• Installation is complete when the system is tune (song), all hardware is working, and applications are ready to use.
Installation Planning Overview

Decide on the boot methods.
Confirm hardware requirements and compatibility.
Choose between an upgrade or a clean install.
Back up data and key files.
Remove or disable conflicts and verify existing settings.
Prepare the hard disk drive and file system.
Partition the hard disk drive with fdisk.
Decide on the Boot Methods
• More than one OS can be installed on the same computer.
• Dual boot installations require you to complete all setup steps for each OS.
• Ensure that one installation doesn’t damage the other, that file systems are compatible, and that all hardware devices and software required by each O.S
are properly accessible.
• You should draw up a compatibility list and note special requirements.
• Installation of Windows over existing Linux corrupt the Linux Boot Loader
Windows 2000 Dual Boot Considerations
• Each OS must reside on a different partition.
• Applications must be installed on each OS.
• When setting up either an MS-DOS or Windows 95 and Windows 2000 Professional dual boot system, Windows 2000 Professional must be installed last.
• If you are using a dual boot machine in a windows NT domain or windows 2000 Active directory network, each OS must have its own machine name in a domain environment.
Windows 98 Dual Boot Considerations
• Drive C must be a FAT16 partition and include enough free space for the Windows 98 installation.
• The two OSs must reside in different partitions or on different hard disks.
• Dual boot systems combining Windows 98 and Windows NT are not recommended because the two O.Ss do not use the same registry settings or device drivers .
• Dual booting Windows 98 and Windows 95 is not possible because both O.S use the same boot file and the second installation will overwrite the first.
• Windows 98 cannot access files on NT file system (NTFS) partitions, and Windows NT cannot access files on FAT32 drives.
Confirm Hardware Requirements and Compatibility
• Ensure that system components meet or exceed system requirements.
• Choose hardware from the hardware compatibility list for Windows 2000.
http://support.microsoft.com/kb/131303 (2000) http://www.microsoft.com/whdc/hcl/default.mspx
(XP) • Choose hardware that is certified to work with Windows 98 and Windows Me.
Update Firmware or Components
• Check the system basic input/output system (BIOS) and update it if necessary before installation.
• BIOS updates can reduce problems and increase performance.
• http://h18023.www1.hp.com/support/files/server/us/romfl ash.html
Choose Between an Upgrade or a Clean Install
• A clean install is done on a new or newly formatted hard disk.
• An upgrade adds new components and updates existing ones.
• The /CHECKUPGRADEONLY option performs a dry run install and reports any possible conflicts. (window 2000)
Record Information and Back Up Data and Key Files
• Create a written record of system configuration and network settings.
• Back up all configuration files and custom Registry entries.
• When performing an upgrade from Windows 95, use Device Manager or Windows NT Diagnostics to print a report of all device and system configurations.
• How to print the system settings in Window XP?
• Back up all data files, batch files, and user profile files.
Remove or Disable Conflicts and Verify Existing Settings
• Antivirus programs, third-party memory managers, terminate-and-stay-resident programs (TSRs), and legacy 16-bit drivers could interfere with the setup program.
• You should ensure that third-party disk partitioning software can be used with the version of Microsoft Windows you are installing.
• When upgrading an OS with CONFIG.SYS
and AUTOEXEC.BAT, you should remove any unwanted 16-bit or legacy entries.
• Upgrades work best when you upgrade in the same product series.
Prepare the Hard Disk Drive and File System
• If the primary drive is already partitioned using the desired file system, you can proceed to the OS setup.
• If you will use FAT16 or FAT32 and need to create or change partitions, you must use the fdisk utility to prepare the drive.
• Fdisk can delete all data on the disk, so back up data first.
• No third-party disk management utilities should have been used to partition the drive.
Partition the Hard Disk Drive with Fdisk
• Windows 98, Windows 95, and all versions of MS-DOS provide fdisk.
• You should use the same fdisk version as the OS you are installing.
• FDISK is the command you use to run the fdisk utility.
• To enable FAT32, you must answer Yes to enabling large drive support.
• Fdisk options include creating and deleting a partition, setting the active partition, displaying partition information, and choosing a drive.
