Mastering Disk Partitioning on Linux with Parted and More

Disk partitioning is a critical part of preparing a hard drive for use. This process involves dividing the storage volume of a disk into smaller, manageable sections known as partitions.

Partitions serve as isolated areas where operating systems, files, and data can be stored. In this article, we will illustrate how to use the Parted tool for disk partitioning and compare it with other partitioning tools.

Using Parted Tool for Disk Partitioning

Parted is a free command-line utility that is used for creating, deleting, resizing, and managing disk partitions on Linux systems. Parted operates in two modes; interactive and command-line mode.

The interactive mode has a simple and easy-to-use interface, while the command-line mode provides advanced functionalities and scripting options. To check the available disks and firmware, you can run the ‘parted -l’ command.

The command displays a list of all available disks, their capacity, the partition table type (GPT or MSDOS), and the firmware type (UEFI or BIOS). You can determine the type of partition table and firmware on a disk by examining the output of the ‘parted -l’ command.

To create partitions using Parted, first, use the ‘mklabel’ command to set a partition label. For instance, to set a new GPT partition label on a disk, type ‘mklabel gpt’.

Once you have set the partition label, the next step involves creating partitions with distinct purposes such as the UEFI System partition, ESP partition, Swap partition, and others. To create a partition, use the command ‘mkpart’ followed by the partition type, starting point, and partition size.

For example, to create a new UEFI System partition, type ‘mkpart ESP fat32 1MiB 513MiB’. Before creating partitions that fill up the entire disk space, be sure to consider ensuring that maintenance and backup spaces are left.

You can use the ‘resizepart’ command to adjust the partition size created on the disk. To remove a partition, use the ‘rm’ command followed by the partition number, for example, ‘rm 2’.

In case of data loss or corrupted partitions, you can use the ‘rescue’ command to recover lost data.

Comparison of Partitioning Tools

Most Linux OS distributions use the fdisk and sfdisk utilities as partitioning tools. Fdisk provides a text-based interface for partitioning disks while sfdisk is a shell-scriptable partitioning tool.

Fdisk is an ideal partitioning tool for bootable devices when managing small disks with few partitions. It also has a compact interface and hotkeys that make it quick and easy to navigate.

On the other hand, sfdisk is suitable for automated partitioning tasks and managing large-scale disks with multiple partitions. Additionally, sfdisk provides scripting options, allowing you to automate partitioning tasks.

Personal preference plays an essential role when it comes to choosing the best partitioning tool. Depending on your needs, you may opt for either Fdisk or sfdisk.

Conclusion

In conclusion, disk partitioning using Parted is simple and easy, though it requires a basic understanding of the command-line interface. Parted provides two modes of operation; interactive and command-line mode, for managing disk partitions.

Fdisk and sfdisk are two of the most popular partitioning tools used by most Linux OS distributions with each having its unique capabilities. It is essential to choose a partitioning tool that best suits your needs.

Disk partitioning is a critical process for managing disk space on Linux systems. Parted is a command-line utility used for creating, deleting, resizing, and managing disk partitions.

Parted operates in two modes: interactive and command-line mode. Other essential tools such as fdisk and sfdisk are also available for disk partitioning.

Fdisk provides a simple interface while sfdisk allows scripting options. Choosing the best partitioning tool depends on personal preference and the specific task at hand.

In summary, disk partitioning is crucial for optimizing disk space and storage management on Linux systems.
