How to add larger than 2TB HDD in Linux

Step 1 

Check the partition label with fdisk command 

fdisk -l 


Step 2 

Now we need to use that in parted command to create partition

parted /dev/sda



Now set the partition table format as gpt with below command

mklabel gpt



Now assign primary partition and assign capacity of the disk with below command

mkpart primary 0GB 4000.8GB



Step 3

Now check the partition that we have created in fdisk

fdisk -l

Now format it with below command

mkfs.ext4 /dev/sda1 



 Now we can mount that partition with below command

mount /dev/sda1 /USB_DISK

 
and also add the same in /etc/fstab 

/dev/sda1               /USB_DISK               ext4    defaults        0 0
 
 
 Now check the mounted partition with df command

df -h
