An overview of Hard disk Partitioning

Disk partitioning is the process of dividing a hard drive disk into multiple units or partitions in order to use different file systems on different unit.

This can be done in order to improve storage space and for the easy access of file systems. Many drives do not have partitions embedded in them. In order to set up a file system or save a file, a disk has to be partitioned.

The hard disk can contain a single partition that can contain all the storage space or the disk can have ten or more partitions as desired. Either way the disk should contain at least one partition, because we just cannot write or save a file on a blank drive.

After creating the partition, the partition is formatted with a file system. Files are then written to that file system on the partition.

Before partitioning we need to know about primary, extended and logical partitions. A disk can normally have only four partitions. If we need more than four partitions, we need to use extended and logical partitions.

Each disk can have only four primary partitions or three primary partitions and one extended partition. So suppose we want 7 partitions on a single disk. We will have to create three primary partitions, an extended partition and four logical partitions or we can create just a single primary partition, an extended partition and six logical partitions.The extended partition effectively functions as a container that allows you to create a larger amount of logical partitions.

Popular software’s like EaseUS Partition Manager and others can help you in partitioning at ease. It is one of the widely downloaded files on the internet and a must have software on your Computer.



Partitioning is easy with graphical tools. While installing an operating system, the operating system installer will offer a partitioning screen where we can create, delete, format, and resize partitions.

We can use graphical tools to manage partitions on the system drive or any other drive. We can modify a partition while in use too. The tools allow you to partition the system drives as well as other internal drives, external drives, USB drives, SD cards and other storage media.

How partition appears as disks

Operating systems display separate partitions as separate drives.

Suppose you have a single drive with 400 GB of storage on your computer, you’d have a C:\ drive with 400 GB of space available to you in Windows. But, if you partitioned that drive in half, you’d have a C:\ drive with 200 GB of space and a D:\ drive with 200 GB of space displayed in Windows Explorer.

These drives may look like two different separate disks, but they don’t function that way. Although they appear as two different disks, they are basically the same physical piece of hardware. You don’t gain the performance benefits from using two separate partitions that you do from using two separate physical drives.

Low C drive can cause your computer to vary in speed and can often cause problem if it’s not resolved properly.Check out this to learn how to increase space in c drive and avoid problems.
