Resizing partitions with fsdisk

What is fdisk?

Fdisk is a command-line utility that allows users to manage disk partitions on Unix-like systems. It is commonly used to create, delete, and resize partitions on a hard drive. Fdisk is a powerful tool that can help users optimize their disk space and improve system performance.

Resizing Partitions with fdisk

Resizing partitions with fdisk can be a complex process, but it is essential for managing disk space efficiently. Before resizing a partition, it is crucial to back up all important data on the disk to prevent data loss in case something goes wrong during the resizing process.

To resize a partition with fdisk, follow these steps:

Step 1: Open fdisk

First, open a terminal window and type «fdisk» followed by the device name of the disk you want to resize (e.g., /dev/sda). Press Enter to launch fdisk and display the disk partition table.

Step 2: Delete the Partition

Next, delete the partition you want to resize by selecting the «d» option in fdisk. Follow the prompts to delete the partition from the disk partition table.

Step 3: Create a New Partition

After deleting the partition, create a new partition with the desired size using the «n» option in fdisk. Follow the prompts to specify the partition type, starting and ending sector, and size of the partition.

Step 4: Write Changes to Disk

Once you have created the new partition, save the changes to the disk by typing «w» in fdisk. This will write the changes to the disk partition table and exit fdisk.

After resizing the partition with fdisk, you may need to format the new partition and mount it to make it accessible in the file system. Remember to restore any backed-up data to the resized partition before using it.
