mount: o dispositivo especial /dev/scd0 não existe

[antharaz]

Bem, a um dia instalei o ubuntu 9.10 e atualizei ele...

até aí blz... mo problema é que agora, na 1ª vez que testo um cd nele, ele não lê o cd e dá esta menssagem de erro:

Código Selecionar Expandir

mount: o dispositivo especial /dev/scd0 não existe


Alguns passos que já testei a partir de outros tópicos daqui, mas não achei a minha solução neles:

A pasta /media/cdrom0 existe.

O meu fstab está certo.

Quando uso sudo mount /dev/scd0 dá o mesmo erro novamente.

Quando fui fazer o boot por um cd do windows, ao escolher a opção do boot, o nome do driver de cd estava diferente do nome normal, mas escolhi mesmo assim e não detectou cd algum.

Pela saída desse comando seu drive de cd não foi reconhecido, e como você disse que não conseguiu dar o boot pelo cd do windows, então acho que deve ter problema com seu leitor ai.
Ele aparece no setup?

[antharaz]

Na bios aparece ATAPI CD ROM(algo do tipo) e não creio que seja problema com ele já que formatei o pc com ele ontem.

O que sai no comando ?

desculpe o trabalho amigo, postei besteira.

o comando é o lshw já postado pelo RonaldoRG, porém sem a chave -C e o argumento disk

sudo lshw

Vá de baixo para cima até encontar a entrada *cdrom. Aí sim. Vamos ver onde ele está.

Deve aparecer algo como este meu:

realmente seu cd rom não existe no sistema...

Se for um desktop, abra o painel lateral com a maquina desligada e faça uma verificação nos cabos de alimentação e cabo de dados.

Algo não está bem por aí.

Caso não deseje abrir a maquina, use o cd do Ubuntu e tente dar um boot por ele.

Se não tiver o cd do Ubuntu use um do Windows mesmo só para conferir se sua unidade de cd está funcionando no boot ( no boot, durante o p.o.s.t., não é usado nenhum sistema operacional, portanto se ler seu cd, o problema seria no Ubuntu mesmo. Se não ler, e "passar direto" ( teclando F8 para escolher o cd rom ) o problema é em sua unidade leitora de cd's.
