Não consigo montar nenhum CD ou DVD na minha unidade. MAS, tenho o Windows 10 em dual boot e consigo ler qualquer CD/DVD no Windows sem problemas.

Nesta imagem, "DVD-RW backup" é o rótulo do DVD-RW. Mensagem do título em inglês: Não foi possível montar o backup do DVD-RW (ou "Não foi possível montar", ou "Não é possível montar", etc.).

• SO : Debian GNU/Linux trixie/sid
• Kernel : 6.12.12-amd64 x86_64
• Dispositivo : ATAPI iHAS122 W

O problema parece ser com a mídia RW. Recentemente, ela voltou a funcionar: consegui ler um CD comercial de um curso de alemão, um filme gravado em DVD-R, um CD de áudio comprado em uma loja, etc. Mas quando insiro um CD ou DVD-RW, o temido pktcdvd0aparece.

Fiz um teste, gravei um ISO em DVD-RW usando growisofs. Funcionou, gravou sem problemas. Porém, logo após a gravação, ele não ejetou o DVD automaticamente, e não conseguiu ler o DVD gravado, apresentando o mesmo erro relatado acima. Não consegui ler nenhuma outra mídia: CD de áudio, curso de alemão, etc. O comando eject /dev/sr0não funcionou, mas o botão de ejeção do drive sempre funciona. Tive que resetar o PC e então consegui ler as outras mídias.

$ sudo cat /sys/kernel/debug/pktcdvd/pktcdvd0/info

Além disso, quando um CD/DVD-RW é inserido, pktcdvd0nunca desaparece (mesmo após a ejeção da mídia). Preciso reiniciar o PC se quiser usar o CD Burner novamente.

Neste exemplo, o DVD-RW já foi ejetado:

$ lsblk
sr0          11:0    1   2,3G  0 rom  
└─pktcdvd0  252:0    1   2,3G  0 disk

$ sudo pktsetup -s      
 0 : 252:0 -> 11:0

$ sudo pktsetup -d 252:0                         
pktsetup: Error: Can't tear down packet device '252:0': Device or resource busy
