랩톱에서 CD를 거의 사용하지 않지만 몇 개월 전에 같은 문제가 발생했다고 생각합니다. DVD 드라이브에 CD를 넣으면 아무 반응이 없습니다. 지난번에 아무것도하지 않고 찼지만 무엇이 잘못되었는지 모르겠습니다. k3b로 CD를 구워야하지만 "광학 장치를 찾을 수 없습니다"라는 오류가 발생합니다.
내 시스템은 Fedora 20 x86_64입니다. 문제 : 드라이브에 CD를 넣을 때 CD가 마운트되지 않습니다.
이 문제를 해결하려면 어떻게해야합니까?
업데이트 현재 : 문제 : 디스크가 보이지 않을 때 "삽입 할 때 마운트하지 않음", "삽입 할 때 마운트하지만 무작위로 연결 해제"/ "무작위로 마운트 해제"와 같이 불안정한 행진 때문에 cd와 dvd가 제대로 작동하지 않습니다. 시스템에 디스크를 꺼낼 수 없습니다.
어제 드라이브에 DVD 영화를 넣었습니다 ./run/media/username/MOUNTPOINT에 마운트되어 eveything이 작동 한 다음 잠시 후에 사라져서 더 이상 마운트되지 않아 드라이브에서 DVD를 꺼낼 수 없습니다. 이것이 현재 상태이며 여전히 드라이브에 있습니다. 다음은 현재 드라이브에서 작동하는 몇 가지 명령입니다.

문제를 진단하기 위해 수행하는 모든 작업이 올바른 것 같습니다. 내 CD에서 나쁜 CD 드라이버, 나쁜 하드웨어를 이해합니다. "아무것도하지 않고 지난번에 찼습니다"라고 언급했을 때 지난번에는 작동했지만 이제는 하드웨어 문제입니다. 드라이브를 마운트하지만 한 번 작동했지만 다시 마운트하지 않으면 하드웨어 고장으로 결론 내립니다.
