Canon SX40의 16GB Kingston SDHC가 있는데 손상되었거나 하드웨어 오류가 발생한 것 같습니다.
카메라에는 일부 사진과 비디오만 표시됩니다(카메라에서 일부 콘텐츠를 읽을 수 없다고 말합니다). 하지만 나는 그곳에서 더 많은 사진을 찍고 싶습니다/필요합니다(현재 멀리 살고 있는 어머니와 어머니 친구의 생일).
SD를 카드 리더기에 연결하면 파일 탐색기(Caja)가 자동으로 열리고 몇 초 후에 닫힙니다. 그 몇 초 동안 DCMI 폴더를 두 번 클릭하여 내용을 볼 수도 있었지만 아무것도 볼 수 없었습니다.
그 몇 초 동안 /sdb1이 /dev에 나타났다가 사라집니다. Gparted나 Photorec 모두 읽을 수 없습니다. 또한 dd는 sdb에서 읽을 수 없습니다.
$ sudo dd if=/dev/sdb of=tarjeta.img bs=512
dd: No se puede abrir '/dev/sdb': No se ha encontrado el medio
또 다른 시도:
$ sudo ddrescue -dr3 /dev/sdb card.image logfile
ddrescue: Can't open input file: No medium found
이번에는 "초" 동안 ddrescue를 다시 시도하십시오... 사라질 때까지:
$ sudo ddrescue -dr3 /dev/sdb card.image logfile
GNU ddrescue 1.24
