Etape 1 : Localisation du disque avec la command fdisk :

La premiere commande localise mon nouveau disque, avec la seconde j’ai plus de détail.

Etape 2 : Formatage, pas question de laisser en mode Windows

# sudo mkfs.ext3 /dev/sdc1
mke2fs 1.44.5 (15-Dec-2018)
/dev/sdc1 contains a exfat file system labelled 'Samsung_T5'
Proceed anyway? (y,N) y

Filesystem UUID: 6db583fc-825f-4a0c-9ea5-dbb79bd6ae9f
Superblock backups stored on blocks:

Ou mieux en ext4 :

# sudo mkfs.ext4 /dev/sdc1
mke2fs 1.44.5 (15-Dec-2018)
/dev/sdc1 contains a ext3 file system
	created on Fri Nov 13 11:49:54 2020

Etape 3 : Le montage automatique :

# mkdir /media/usbdisk-1

Voir le uuid :

# ls -l /dev/disk/by-uuid/*
lrwxrwxrwx 1 root root 10 nov.  10 10:20 /dev/disk/by-uuid/1D2E-E63C -> ../../sda1
lrwxrwxrwx 1 root root 10 nov.  10 10:20 /dev/disk/by-uuid/5fa91220-4d17-485d-bb7d-3e41fc04e15b -> ../../sda2
lrwxrwxrwx 1 root root 10 nov.  10 10:20 /dev/disk/by-uuid/64b51c15-9706-4ac5-a369-774ce9539762 -> ../../sda3
lrwxrwxrwx 1 root root 10 nov.  13 15:05 /dev/disk/by-uuid/bf1d9240-ba6d-4230-8e4e-dd20218231e8 -> ../../sdc1
lrwxrwxrwx 1 root root 10 nov.  10 10:20 /dev/disk/by-uuid/c8478b72-fcaf-4dc7-87a7-5156cc19efab -> ../../sdb1
lrwxrwxrwx 1 root root 10 nov.  10 10:20 /dev/disk/by-uuid/d4f59815-be3d-437c-b204-ca794d170ce9 -> ../../sda4

Ajouter dans /etc/fstab :

UUID=bf1d9240-ba6d-4230-8e4e-dd20218231e8 /media/usbdisk-1 ext4 errors=remount-ro 0 1

Monter le disque ensuite :

# mount /media/usbdisk-1
# df -h
