When you get a new hard disk and use fdisk or parted partition, just follow the steps. If you use fdisk, it is suitable for disks less than 2TB. The steps are: view the device name, start fdisk, create partitions, set partition type and size, and write changes; if you use parted, it is suitable for disks greater than 2TB or require GPT format. The steps include confirming the device, entering parted, setting the GPT partition table, creating partitions and exiting; finally, no matter which tool is used, the partition needs to be formatted and mounted.

When you get a new hard disk and want to use fdisk or parted to partition, as long as the steps are clear and the operation is careful, there is no big problem. Both tools can complete tasks, but the style and usage are slightly different. The following will explain how to use them to complete the basic partitioning operation.

Using fdisk partitions: Suitable for traditional MBR partition tables

fdisk is an old command line partitioning tool suitable for disks less than 2TB, using the MBR (main boot record) partition format.

The basic operation process is as follows:

1. Check the disk device name
   Run lsblk or fdisk -l to view the identified disk devices in the system. For example, your new hard drive may be /dev/sdb .

2. Start fdisk
   Execute the command:

    sudo fdisk /dev/sdb

3. Create a new partition

   • Enter n to create a new partition
   • Select primary or extended partition
   • Set the starting sector (usually, the default entry is required)
   • Set the end sector (50G can be entered to indicate the allocation of 50GB)

4. Write changes and exit

   • Enter w to save and exit

Note: After the operation is completed, you can use lsblk or fdisk -l to confirm whether partition devices such as /dev/sdb1 have been generated.

Using parted partitions: Supports GPT and large-capacity disks

If your hard drive is more than 2TB, or you want to use GPT (GUID partition table), then it is recommended to use parted , which is more friendly to modern hardware.

Common operation steps:

1. Confirm the device name Also use lsblk to confirm the device path, such as /dev/sdb

2. Enter parted tool

    sudo parted /dev/sdb

3. Set the partition table type to GPT

    (parted) mklabel gpt

4. Create a partition For example, create a partition from 0 to 100GB:

    (parted) mkpart primary ext4 0GB 100GB

5. quit Enter quit to exit

Tip: parted is effective immediately, unlike fdisk, which requires manual "write". Therefore, you must confirm and execute every step clearly.

Format partition: Don't forget this step

No matter which tool you use to divide the zone, you still need to format the partition to mount it.

For example, use the ext4 file system to format /dev/sdb1 :

 sudo mkfs.ext4 /dev/sdb1

Then you can mount it to the directory and use it:

 sudo mount /dev/sdb1 /mnt/data

Remember to automatically mount if you want to boot and modify the /etc/fstab file.

Basically that's it. fdisk is more suitable for old-school users and small-disk operations, and parted is more modern, suitable for large-capacity and GPT scenarios. Both tools are powerful, but both require careful operation to avoid accidentally damaging existing data.
