Many people may have questions, what is the hard disk partition? Why is it necessary? Any USB drive on your computer’s hard drive; if you want to write a file on it, then there must be at least one partition. Without a partition, you cannot write any files on the drive, but why? Let’s try to find answers from this article.
What is Hard Drive Partition?
There are already single partitions in the purchase of a new drive or pen drive. But most of the drive’s spaces show up in new condition as unused space, which means there is no partition in this space. And in order to write a file in this empty space, you will need a partition and this partition must have a file system. The hard disk partition is the logical division of that drive, which can be seen as a separate unit and file system. Your computer’s operating system and the file system can manage all partitions very well and simply, as they think that each individual partition isolated to a different physical drive. Dividing all the hard drives into smaller parts makes it possible to manage it more efficiently.
Partitions are essential, without Partition Part You cannot start to write files on the empty space. Suppose you have a table space, now you want to keep 1 liter of water there, how to keep the water on the table? Of course, there will be a need for a pot, and you can say this part of the partition. Different types of utensils are needed to store liquids and gases, as well as how different files will be written on the hard drive, it is necessary for different file systems.
There is a disk partition manager in the operating system, which helps system administrators to create many partitions, to resize the partition size, to delete partitions. After creating a new partition, it is not possible to store the file immediately, but the file system must be formatted. The NTFS file system is used for Windows Drive. Fat / Fat 32 usually supports any operating system and any device. HFS + File System for Mac and EXT4 File System for Linux.
Why is partition necessary?
The drive has a bootable partition, which usually occupies the operating system, and the operating system first reads this partition. After a computer boot, a process is run which helps the OS to understand and access the partition table, as well as to help determine the partition table, how many partitions have and the key file system format. It helps to mean the size, address, etc. of each partition.
You do not want to have multiple partitions in your pen drive or on the memory card because if you make multiple partitions, your computer will show it like multiple drives. However, there are many other reasons for using multiple partitions, which create value for multi-partitioning. Generally, Windows is installed on C drive, if you do not have any other partition on your hard disk, then restarting your Windows will easily remove your other files. For this reason, most windows users create a separate partition and prefer to store their personal files. In order to reinstall Windows, all the data should not be renewed.
Suppose, if you want to use Linux and Windows together with the same hard drive to dual boot, then Linux and Windows will mess around with the installation of two OS in the same partition. Besides, Linux requires a separate partition to install, and Linux uses a different file system format. A partition is sufficient to install Windows operating systems, but multiple partitions are needed to install Linux.
For example, a swap partition of the Linux system is required, when your system turns out to be full of RAM, the Linux swap collects the necessary files in memory. Swap partition must be formatted with a separate file system.
Primary, Extended and Logical Partition
Before formatting hard disk partitions and file systems, be aware of some important information about disk partitions. It is possible to create only four primary partitions on a drive. If you create four primary partitions, then three primary partitions will be created and one extended partition will be created. An extended partition is a partition that can create different partitions. And the partitions created in this extended partition are called logical partitions.
Suppose you need 4 or fewer partitions, but it is possible to make 4 primary partitions comfortably. Again, if you need to create 6 partitions, then you have to create 3 primary partitions and create an extended partition and create three more logical partitions in this extended partition. Primary partitions can usually contain your operating system, and you can boot the computer from the primary partition. An extended partition does not automatically have a partition, but it contains logical partition drives. Logical drives are created especially for any types of files except operating systems, such as audio, video, games etc. on your computer. If you want to create 6 partitions, one primary partition and one extended partition where you can create 5 logical drives.
A question in should your mind right now that, separate partition drives show you different drives on your operating system, are they performs different drives from each drive? Unfortunately, different partitions show different drives, but there is no improvement in performance. Since all the partitions are from the same physical drive, so bandwidth speed behaves like a partition, do not get dedicated speed from a different partition. But if you have a separate physical drive installed on your computer, you will see performance improvements.
