Cara Format Hard Disk di Linux

Q. I’ve installed a new 3 TB SATA hard disk on our office Ubuntu Linux . How do I format a hard disk under Linux operating system from a shell prompt?

A.. There are total 4 steps involved for hard disk upgrade and installation procedure:

Step #1 : Partition the new disk using fdisk command

Following command will list all detected hard disks:

# fdisk -l | grep '^Disk'

Output:

Disk /dev/sda: 251.0 GB, 251000193024 bytes
Disk /dev/sdb:  3.0 TB, 3000000193024 bytes

To partition the disk – /dev/sdb, enter:

# fdisk /dev/sdb

The basic fdisk commands you need are:

  • m – print help
  • p – print the partition table
  • n – create a new partition
  • d – delete a partition
  • q – quit without saving changes
  • w – write the new partition table and exit

So, to create a new partition, you must press, ‘n’   .. and follow steps and answer / enter few options .

Step#2 : Format the new disk using mkfs.ext3 command

To format Linux partitions using ext2fs on the new disk:

# mkfs.ext3 /dev/sdb1

Step#3 : Mount the new disk using mount command

First create a mount point /disk1 and use mount command to mount /dev/sdb1, enter:

# mkdir /disk1
# mount /dev/sdb1 /disk1
# df -H

Step#4 : Update /etc/fstab file

Open /etc/fstab file, enter:
# vi /etc/fstab

Append as follows:

/dev/sdb1               /disk1           ext3    defaults        1 2

Save and close the file.

Task: Label the partition

You can label the partition using e2label. For example, if you want to label the new partition /backup, enter
# e2label /dev/sdb1 /backup
You can use label name insted of partition name to mount disk using /etc/fstab:
LABEL=/backup /disk1 ext3 defaults 1 2
