안전한 복사 후 오디오 CD 복구

K3B나는 (몇 년 전에 구운) 오디오 CD를 리핑(사용하거나 다른 방법으로) 하고 싶습니다 flac. K3B그렇게 할 수 없어서 CD가 손상되었음을 깨달았습니다.

safecopy매개변수를 사용하여 데이터를 복구했습니다 --stage-1-3. 출력(아래 참조)에서 데이터가 올바르게 복원된 것으로 나타납니다.

그러나 파일을 마운트하고 거기에서 가져올 수 있기를 원합니다. 불행히도 이것은 사실이 아닌 것 같습니다.

$ sudo mount -o loop -t iso9660 diskimage /media/cdrom1/
mount: block device /mnt/data/Bureau/diskimage is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg별로 유용한 출력이 표시되지 않습니다.

$ dmesg | tail
ISOFS: Unable to identify CD-ROM format.

실제로는 인식할 수 없는 형식인 것 같습니다.

$ file diskimage 
diskimage: data

당연히 파일 이름을 .iso, .raw, .img또는 .bin.

인터넷에서 누군가가 사용을 추천했지만 ccd2iso역시 실패했습니다( Unrecognized sector mode (0) at sector 0!).

이 원시 데이터 덤프에서 오디오를 계속 추출하려면 어떻게 해야 합니까?

이것이 출력입니다 safecopy. 비 었다 stage3.badblocks.
