TestDisk exited normally.
e2fsck를 사용하여 나열된 모든 백업 블록을 사용해 보았지만 모두 유효하지 않은 것으로 돌아왔습니다. testdisk를 통해 백업 복원을 시도했지만 여전히 동일합니다. 이미지를 위한 2TB의 여유 저장 공간이 없기 때문에 낮은 수준의 dd= 유형 솔루션 없이 드라이브를 복구하고 싶습니다. :( 장점은 시스템 볼륨이 아니므로 마운트/마운트 해제를 시도하는 것이 쉽습니다. 다른 질문은 없습니다. .
모든 도움에 감사드리며, 슬픈 이야기로 끝나는 경향이 있는 포럼 게시물을 20탭 정도 열었습니다.
답변1
더 많은 정보가 손실되지 않도록 손상된 드라이브를 즉시 이미지화하는 것이 좋습니다. 귀하의 하드웨어는 불량일 가능성이 높으며 귀하가 좌절감을 느끼지 않는 한 다시는 망치지 않을 것입니다.
이미지를 새 디스크에 복원한 후 복원을 시도할 수 있습니다. 하지만 데이터가 극도로 중요하지 않다면 이는 시간이 많이 걸리고 실망스러운 작업이 될 것이라고 확신합니다.
안타깝게도 가장 좋은 접근 방식은 기존 디스크를 삭제하고 새 디스크를 설치한 다음 보관해야 하는 세부적인 백업에서 복원하는 것입니다.
