Macintosh HD 디스크에 갑자기 오류가 발생했습니다(시스템이 더 이상 부팅할 수 없습니다. diskutil이 B-트리 문제에 대해 불평했습니다. 과거에 다양한 diskutil 명령을 시도했지만 성공하지 못했습니다). ddrescue를 사용하여 복구하려면(현재는 Linux 기반 컴퓨터만 사용하고 있습니다) - 다음 명령을 사용하세요.
ddrescue -f -r0 -n -d /dev/sdc /storage/macos.img /storage/macos_recovery.log
오랜 시간이 흐른 끝에 오늘 처리가 종료되어 매우 실망스러운 결과가 나왔습니다.
이것은 2012 MacBook에 장착된 기본 500GB HDD HFS+ 디스크입니다. 첫 번째 줄에서는 모든 것이 거의 잘 작동하므로 거기에 몇 가지 중요한 파일을 저장할 수 있을 것 같습니다(보통 100kb 미만이므로 희망이 있을까요?). img 파일에서 시도한 내용은 다음과 같습니다.
1 - 사진을 찍으려고 했는데 쓸모없는 txt 파일 외에는 아무것도 찾을 수 없었습니다.
2 - testdisk를 사용해 보았습니다. 분할되지 않은 디스크가 보고되었고(어차피 EFI GPT로 설정했습니다) 모든 곳에서 임의의 HFS+ 파티션이 발견되었습니다.
3 - 현재 gparted 파티션 복구를 시도 중입니다.
내 질문은 다음과 같습니다.
- 디스크는 500GB이고 출력 img 파일은 931G입니다. 어떻게 이럴 수있어?
- 이러한 손상 패턴의 원인은 무엇입니까? 나는 stackX 사이트에서 다양한 패턴을 본 적이 있지만(보통 선형 - 디스크 긁힘과 같은), 이와 같은 규칙적인 파도는 본 적이 없습니다. 이 문제가 해결될 수 있나요?
파티션 맵을 수동으로 재구축할 수 있도록 2012 맥북 디스크에 대한 원본 정보를 어디서 찾을 수 있습니까(예: 복구 HD/Macintosh HD 파티션이 시작/끝나는 위치에 대한 정보)?
- 혼란에서 회복하는 방법에 대한 다른 아이디어가 있습니까?
감사합니다!

하드 드라이브가 녹색 섹션(양호 섹터)에서는 소음 없이 완벽하게 작동하는 것을 확인했지만, 불량 섹터에서 이상한 소음이 발생하기 시작했습니다(반복적으로 낮고 조용한 노크 소리 및 일부 높은 음조의 "오래된 하드 드라이브" "읽기) ) 소음). 어제 디스크를 열어보니 헤드가 정지 위치로 돌아가서 탑플레이트가 완벽해 보이네요. 불타거나 옮겨진 것은 없는 것 같습니다. 이 소음이 어디서 나오는지 아시나요?
