Improved Organization and Management of Data: Disk management allows users to divide their hard disk into partitions, which can be treated as separate storage devices.

Efficient Use of Available Storage Space: Disk management allows users to optimize their storage space by creating partitions of different sizes and formatting them to different file systems. This ensures that the available storage space is used efficiently.

Improved Data Access and Processing: When the hard disk is well-organized and optimized, the computer can access and process files faster, leading to improved performance.

Prevention of Data Loss and Corruption: Regular disk maintenance, such as defragmentation and backup, can help keep files safe and secure, preventing data loss and corruption.

Important Aspects of Disk management in OS

There are some most remarkable parameters, which are going to use for disk management in operating system, including:

• Disk Format (low-level format or physical format)
• Booting from disk
• Bad block recovery

Disk Format

Disk formatting is the process of preparing a data storage device for initial use by creating a file system on it. Disk formatting is an essential task in disk management, as it prepares the disk for use and ensures that it is compatible with the operating system and other software.

There are several disk formatting tools available for different types of operating systems, including Windows Disk Management, Disk Utility on Mac OS, and GParted on Linux. Some third-party disk formatting tools include EaseUS Partition Master, Acronis Disk Director, and Macrorit Disk Partition.

Disk formatting tools allow users to format disks, change the file system, force dismount partitions, and assign a new drive letter and file system format to the target device.

Boot Block

Boot block is a region of a hard disk, floppy disk, optical disc, or other data storage device that contains machine code to be loaded into RAM (Random Access Memory) by a computer system’s built-in firmware. The boot block is responsible for initiating the booting process of the system and contains all the data and instructions required for starting the booting process of the system.

The boot block is designed to be small and efficient, allowing the operating system to load quickly during the boot process. The boot block is always located at a fixed location on the disk where it can be easily changed, and a new version can be installed.

Bad Block

In disk management, bad blocks refer to areas of storage media that are no longer reliable for storing and retrieving data due to physical damage or corruption. Bad blocks can be caused by physical damage to the disk, software errors, manufacturing defects, wear and tear, head crashes, power failure, and other factors. Disk utility software, such as CHKDSK on Microsoft Windows systems or badblocks on Linux systems, can scan storage media and mark the failed sectors so that the operating system doesn’t use them.

The firmware on an HDD controller can also identify and mark a bad block as unusable. Disk utility software can be used to scan storage media and mark the failed sectors so that the operating system doesn’t use them.

Disk Management Tasks

Disk management in operating system enables various tasks, which are essential for maintaining the healthy and efficient entire storage system. Here are some common disk management tasks, including:

Formatting: This involves preparing a disk for use by creating a file system on it. This process typically erases all existing data on the disk.

Partitioning: This involves dividing a single physical disk into multiple logical partitions. Every partition can be worked as a separate storage device that are allowing for better organization and data management.

Mounting: This involves making a partition or disk available for use by the operating system and applications.

Resizing: This involves changing the size of a partition, either by shrinking or extending it.

Defragmentation: This involves reorganizing the data on a disk so that related pieces of information are stored closer together, which can improve disk performance.

Backup and Recovery: This involves creating backups of important data and restoring it in case of accidental deletion or system failure.

Disk Clean up: This involves removing unnecessary files and programs from a disk to free up space and improve performance.

Types of Partitions in Disk Management

Disk management involves several tasks, including partitioning, formatting, resizing, defragmentation, backup and recovery, and disk cleanup. When it comes to partitioning, there are mainly three types of partitions that can be created in disk management:

Primary Partition

Primary partition is a type of partition used to store the operating system and its files. It is the only partition that can be set active, and it is typically the C: drive in Windows 10. A hard disk can have up to four primary partitions, and only one primary partition can be made active at a time.

Primary partitions can be created during the Windows installation process or after Windows has been an installed using built-in tool such as Disk Management or DiskPart. By creating the primary partition is essential in installing an operating system on your computer system.

Extended Partition

Extended partition is a special type of partition that can hold multiple logical partitions. It acts as a container for logical partitions and is used to extend the maximum number of drives that can be assigned to the same physical disk. A hard disk can only hold one extended partition at a time, but the extended partition can be divided into several logical partitions.

Logical partitions are created within the extended partition and can be used to store data or install an operating system. The Extended Boot Record (EBR) provides information about the logical partitions contained in the extended partition. Logical partitions are assigned drive letters after they are formatted with the appropriate file system.

Logical Partition

Logical partition is created within an extended partition. It is used to store data or install an operating system, but it cannot be set as active. A hard disk can have multiple logical partitions, and each logical partition can be assigned a drive letter after it is formatted with the appropriate file system. Logical partitions are used on hard drives that are partitioned using the MBR (Master Boot Record) partition method, which is found in older computers.

A Master Boot Record only has enough available bytes to describe 4 partitions, which is plenty, even for today. But for situations where more than 4 partitions are needed, a hack was created that made it possible to divide one partition into sub-partitions that were called logical partitions.

Logical partitions were never a really good idea, and something to be used only if really necessary, because the logical partitions were not described inside the MBR itself – they were described inside the partition that was being divided.

How to Access Disk Management in OS?

There are several ways to access disk management in operating system, but depending on the specific operating system being used. Here are some common methods, like as:
