How to find out what device name in /dev directory is my DVD/CD Writer/Burner in the Linux Terminal

How to find out what device name in /dev directory is my DVD/CD Writer/Burner in the Linux Terminal


Best 3 ways on how to find out what device name in /dev directory is your DVD/CD Writer/Burner in the Linux Terminal: 



1.) By checking /proc/sys/dev/cdrom/ , issue command in terminal:

        $ cat  /proc/sys/dev/cdrom/

        /or

        $ less  /proc/sys/dev/cdrom/

        /or

        $ more  /proc/sys/dev/cdrom/

- a sample output in a laptop can look like this (showing other data including other device functions and even the drive speed):

drive name:        sr0
drive speed:        24
drive # of slots:    1
Can close tray:        1
Can open tray:        1
Can lock tray:        1
Can change speed:    1
Can select disk:    0
Can read multisession:    1
Can read MCN:        1
Reports media changed:    1
Can play audio:        1
Can write CD-R:        1
Can write CD-RW:    1
Can read DVD:        1
Can write DVD-R:    1
Can write DVD-RAM:    1
Can read MRW:        1
Can write MRW:        1
Can write RAM:        1

- The device name is: sr0
- So the device is in /dev/sr0


2.) With lsblk, issue command in terminal:

$ lsblk

- a sample output in a laptop can look like this:

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 111.8G  0 disk
├─sda1   8:1    0   300M  0 part
├─sda2   8:2    0   128M  0 part
├─sda3   8:3    0 110.5G  0 part
└─sda4   8:4    0   900M  0 part
sr0     11:0    1   4.4G  0 rom
loop0    7:0    0   765M  1 loop /lib/live/mount/rootfs/filesystem.squashfs
zram0  254:0    0  1002M  0 disk
zram1  254:1    0  1002M  0 disk
zram2  254:2    0  1002M  0 disk
zram3  254:3    0  1002M  0 disk
zram4  254:4    0  1002M  0 disk
zram5  254:5    0  1002M  0 disk
zram6  254:6    0  1002M  0 disk
zram7  254:7    0  1002M  0 disk

- In the TYPE Column look for ROM, so the device name here is sr0
- So the device is in /dev/sr0


3.) With inxi, issue command in terminal, make sure to type is as you see it, that O in Optical has to be capitalized, or just copy and paste it:

$ inxi -d | grep Optical

- a sample output in a laptop can look like this:

Optical: /dev/sr0 model: HL-DT-ST DVDRAM GUD0N dev-links: N/A

- The device name is sr0, in /dev as /dev/sr0
