Não consigo encontrar meu drive de DVD no Ubuntu 16.04

Question

Eu acho que você poderia dizer que eu sou um noob um pouco educado (eu sei, um pouco de conhecimento é uma coisa perigosa).

Minha unidade funcionou bem no Mint 17.3, mas agora estou executando o Lubuntu 16.04 e a minha unidade de DVD ainda não funcionou. Eu tentei vários CDs e DVDs; música, dados e espaços em branco.

lsblk -f retorna:

NAME   FSTYPE LABEL    UUID                                 MOUNTPOINT
sda

sr0          

cat /dev/sr0 retorna:

cat: /dev/sr0: No medium found

Então, eu tentei lshw e entendi:

*-scsi
     physical id: 2
     logical name: scsi0
     capabilities: emulated
    *-cdrom
         description: DVD-RAM writer
         product: DVD RW AW-G540A

         logical name: /dev/cdrom
         logical name: /dev/cdrw
         logical name: /dev/dvd
         logical name: /dev/dvdrw
         logical name: /dev/sr0
         version: 1.W0
         serial: [
         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
         configuration: ansiversion=5 status=nodisc

E depois tem isto:

$ mkdir ~/dvd | sudo mount /dev/sr0 ~/dvd
mount: no medium found on /dev/sr0

Eu estou muito empolgado com palha neste momento. Então, e agora?

Atualização de informações: posso localizá-lo em Discos sem problemas, mas não mostra mídia quando tenho um DVD na unidade. Eu já limpei a lente, mas isso nunca foi um problema, pois funcionou bem antes de instalar o Lubuntu 16.04

Answer 2

Na verdade, o seu sistema encontra o drive e o identifica corretamente, como um DVD Sony RW AW-G540A. Sua saída fornecida indica que a dificuldade está na leitura da unidade que o sistema está convencido de que está vazio como você mencionou. A causa raiz é provavelmente um laser com falha (desde que você limpou a lente). O dispositivo, se for reparável, não vale a pena o custo de reparo. Eu recomendo a substituição da unidade ou do laptop inteiro (se o orçamento permitir) considerando a idade.

    

Answer 3

só fiz da parte - "Não jogue a toalha"
Eu tenho o Optiarc DVD RW AD-7530B (NX02)

1. sudo add-apt-repository ppa:brandonsnider/cdrtools
2. sudo apt update
3. havia 3 pacotes, então eu fiz: sudo apt-get dist-upgrade
4. sudo apt install cdrecord mkisofs
5. reiniciar

isso é tudo, funcionou para mim, fez o meu dia, obrigado
