fat32 형식의 USB 드라이브를 시스템에 연결했습니다. dmesg보여주다:
[ 4057.783200] sd 6:0:0:0: [sdd] Optimal transfer size 33553920 bytes not a multiple of physical block size (4096 bytes)
...
[ 4064.091218] FAT-fs (sdd1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
이 드라이브는 MacOS, Win, Linux용이므로 fat32입니다. 짧은 정전으로 인해 이런 일이 여러 번 발생했습니다. 평소와 같이 man fsck옵션을 확인 하지 않고 Gparted를 사용하여 디스크를 확인했습니다 .
하지만 이번에는 디스크만 검사하는 것이 아니라 디스크를 완전히 지웁니다. 시스템 로그에는 아무 것도 알려주지 않습니다.

/var/log/messages그리고 그것은 journald더 이상 도움이 되지 않습니다. 디스크 자체는 괜찮습니다. 단지 비어 있고 거기에 저장한 데이터가 포함되어 있지 않습니다.
디스크가 마운트 해제되었습니다. 데이터를 복구할 수 있는 방법이 있나요?
명령에서는 디스크를 다시 마운트하고 명령을 다시 실행했다고 sudo systemctl cat media-pg1-E93B\x2d1A8F.mount보고했지만 아무것도 반환하지 않았습니다. No files found for media-pg1-E93Bx2d1A8F.mount.재설치 후 시스템 로그:
