# write partition with parted
[lee@hwang29 ~]$ sudo parted /dev/sda

(parted) mkpart primary 0GB 3000GB # create primary partition, assaing disk capacity
(parted) quit


# Creating an ext4 File System
[lee@hwang29 ~]$ sudo mkfs.ext4 /dev/sda

# mount disk
[lee@hwang29 ~]$ sudo mount /dev/sda /data_1

# add entry to /etc/fstab for permanent mounting
[lee@hwang29 ~]$ vim /etc/fstab
/dev/sda    /data_1    ext4    defaults    0    0


tip for naming the disk
- /dev/disk/by-id/scsi-SATA_ModelName_partion1 instead of  /dev/disk/sda
- if you are using multiple disk/partition and one of them is failed, it is easy to identify which disk and partition goes wrong
- if you change, add, move disk, it might cause problems because other disk already use name sda, sdb
