Format HDD on Linux from Terminal

This is a quick one but good to know.

Start with the drive you want to use and check what is on it.

fdisk -l

Then start fdisk

sudo fdisk /dev/sda

Use the following commands shortcuts in fdisk:

• Create a new partition table : g (for GPT, use help for other format)
• Create a new partition : n
  Default values work for single partitions.
• Write and exit fdisk: w

When you run fdisk -l again, you’ll see a new partition.

That’s it!
