🧭 Step-by-Step Guide to Format a Disk on Linux

1. Identify the Disk

bash
CopyEdit
lsblk

or

bash
CopyEdit
sudo fdisk -l

Look for the correct device name (e.g., /dev/sdb). Make sure it’s the right one.

2. Unmount the Disk (if mounted)

bash
CopyEdit
sudo umount /dev/sdX1

Replace sdX1 with the correct partition (e.g., /dev/sdb1). Do this for all partitions on the disk.

3. (Optional) Wipe Existing Partition Table

bash
CopyEdit
sudo wipefs -a /dev/sdX

or

bash
CopyEdit
sudo dd if=/dev/zero of=/dev/sdX bs=1M count=100

4. Create a New Partition Table

Use fdisk (for MBR) or gdisk/parted (for GPT):

bash
CopyEdit
sudo fdisk /dev/sdX

Inside fdisk, do the following:

• o – create a new empty DOS partition table
• n – create a new partition
• w – write changes and exit

5. Format the Partition

Choose the file system type:

• ext4 (common for Linux):

  bash
  CopyEdit
  sudo mkfs.ext4 /dev/sdX1
  

• xfs:

  bash
  CopyEdit
  sudo mkfs.xfs /dev/sdX1
  

• fat32 (for compatibility with Windows/macOS):

  bash
  CopyEdit
  sudo mkfs.vfat -F 32 /dev/sdX1
  

6. Mount the Formatted Disk

bash
CopyEdit
sudo mkdir /mnt/mydisk
sudo mount /dev/sdX1 /mnt/mydisk

✅ Done!

If you want to make the mount permanent, you can edit /etc/fstab.
