SMART에 따르면 9년이 넘는 작업 끝에 NAS 2TB WD 디스크가 부팅되지 않았습니다. 나는 그것을 꺼내서 컴퓨터에 연결하여 무엇이 잘못되었는지 확인했습니다.
Ubuntu Disks 유틸리티는 기본적인 SMART 테스트도 수행할 수 없습니다.
fsck /dev/sdc4I/O 작업을 수행할 수 없다는 오류 메시지가 표시되었기 때문에 베어 명령을 실행할 때 실수를 했을 수도 있습니다 .
시스템을 다시 시작하면 상황이 더욱 악화됩니다. 이제 디스크가 없습니다 /dev/. 그래서 나는 노력했다
에코 "0 0 0">/sys/class/scsi_host/host2/scan
그리고 상담했다 dmesg. 다음과 같이 실행됩니다.

이를 통해 하드 드라이브에 불량 섹터가 있어 제대로 연결되지 않고 기존 파티션 3개(EXT3 또는 4, 잊어버렸습니다)를 인식하지 못한다는 사실을 알게 되었습니다.
그래서 저는 이제 추가 전략을 결정하고 싶습니다.
먼저 하드디스크를 다시 살펴보고 싶은데 /dev/가능한지 모르겠네요. 다음으로 불량 블록을 처리해야 합니다. 아니면 dd(또는 다른 도구)를 사용하여 먼저 데이터를 안전한 장소에 복사 해야 합니까 ?
