내 친구가 WD Elements 1TB USB 외장 드라이브를 가지고 있는데 약간의 충돌이 발생했습니다. 가능하다면 무엇이든 복구하는 것을 고려하고 있습니다.
이미지를 만들 수 있는지 확인하기 위해 Debian 워크스테이션에 연결했습니다. HDD의 LED가 켜졌습니다. 하지만 설치되지 않았습니다(상황에 따라 예상했던 대로일 것입니다).
dmesg 출력은 여기에 있습니다. 시작하는 데 시간이 오래 걸리는 것 같습니다.

결국에는 dd 작업을 시작했지만 실제로는 바이트를 쓰지 않았고 결국 디스크 연결이 끊어지는 것처럼 보였습니다.
이는 디스크나 USB 커넥터에 문제가 있음을 의미합니까?
별도의 USB 3.0-SATA 브리지가 있고 WD Elements에서 내부 디스크를 꺼내서 시도해 볼 수 있습니다. 하지만 이 단계에서 어떤 차이가 있는지 확실하지 않습니까?
아니면 우리가 시도할 수 있고 어떤 방식으로든 이미지를 캡처할 수 있는 다른 방법이 있나요?
답변1
결국에는 dd 작업을 시작했지만 실제로는 바이트를 쓰지 않았고 결국 디스크 연결이 끊어지는 것처럼 보였습니다.
면책조항: 디스크 손상의 정확한 정도를 말하기는 어렵습니다. 적어도 디스크의 첫 번째 부분이 손상된 것으로 보입니다.
먼저 ddusing을 사용하여 일부 블록을 건너 뛰어 보세요 skip=. 문제는 아마도 디스크 시작 부분 근처의 결함 있는 부분일 것입니다(=>운이 좋다).
예를 들어 타워에서 SATA를 통해 직접 디스크를 연결해 볼 수도 있지만 SATA->USB 포트가 될 것으로 생각됩니다.
나는 보통 가능한 것을 복구하기 위해 testdisk를 사용합니다. 약간의 히트와 미스입니다. 작업에 적합한 도구를 사용하십시오.
