Lesson 4 : Partitioning and Formatting

4.1. Learning Objectives 
On completion of this lesson you will be able to describe:
 How to partition a hard disk drive
 How to format a hard disk drive.

4.2. Hard Disk Partitioning

Partitioning a drive means dividing a hard drive in several independent portions so that each portion works as an independent hard disk. We can make more than one drives in one hard disk using partitioning. For example, if we install one hard disk in the PC chassis, by partitioning we can make 3 drives named as C:, D: and E: in the one disk. DOS 6 supports hard drive of maximum size 2.1 GB. DOS does not support more than 2.1 GB size of hard drive. So we can not use a 5.1 GB drive directly in DOS. To use it in DOS it should be partitioned in several portions so that each portion is not larger than 2.1 GB. So to use the 5.1 GB Hard disk in DOS environment it may be partitioned to 3 drives with size of: 

 Drive C: 2.1 GB 

 Drive D: 2.1 GB 

 Drive E: 0.9 GB 

Some times two operating systems may not reside in one drive. They may require one separate drive for each operating system. To run all these operating systems in one hard disk, the disk should be partitioned. To make a disk usable it should be partitioned. Even if we make only one drive from a hard disk, then it should also be partitioned. Some reasons of partitioning: 

 Making a hard disk usable 

 Dividing a disk to get several drives 

 Dividing a large disk in smaller size so that DOS can support it. 

 Running several operating systems in one hard disk.
