안녕하세요 여러분, 저는 두 개의 동일한 USB 드라이브를 가지고 있는데 완전히 잘못 작동하고 있습니다...
여러 파일을 복사한 후 마운트를 해제하고 캐시에 쓰기 위해 15분 동안 기다린 후(이상하게도 CPU 로드가 0임) 포기하고 드라이브만 제거했습니다.
이제는 단순히 사용할 수 없습니다. 일부 파일은 존재하지 않는다고 생각했지만(아무것도 기록되지 않았기 때문에) 다음과 같은 동작은 없습니다.

ID가 24ae:1100인 장치가 카드 리더라는 것을 알고 있으므로 ffff:1201은 펜 드라이브임에 틀림없습니다.

어느 시점에서는 장치가 제거되었다가 다시 연결되었다는 메시지가 표시되며(물론 지금까지 이 작업을 여러 번 수행했기 때문에) 다시 연결이 끊어진 것으로 표시되지 않습니다.
GParted는 드라이브를 표시하지 않습니다(크기를 확인할 수 없기 때문입니다). Windows 7 및 Windows 10에서는 이를 표시 diskmgmt.msc하지만 사용할 수 있는 크기가 없습니다(둘 다 삽입된 미디어가 없다고 생각합니다(카드 리더기와 비슷하지만 확실히 그렇지 않습니다). Testdisk는 장치를 표시하지 않습니다. 수동으로 마운트 장치도 가능한 원인이 아닙니다 ...
다음과 같은 이유로 전체 장치를 0으로 설정하려는 시도가 dd실패했습니다.
marc@DESKTOP:~$ sudo dd if=/dev/zero of=/dev/sde count=32G
[sudo] Passwort für marc:
dd: konnte '/dev/sde' nicht öffnen: Kein Medium gefunden
marc@DESKTOP:~$
(드라이브는 32GB여야 하므로 count 매개변수가 실제로 의미가 있습니다.)
기본 SCSI 장치에 대한 지식을 사용하여 다음을 수행할 수 있습니다.
marc@DESKTOP:~$ sudo dd if=/dev/zero of=/dev/sg5 count=32G
dd: Schreiben in '/dev/sg5': Das numerische Argument ist außerhalb des Definitionsbereiches

그래서 적어도 뭔가가 일어나고 있습니다. 비록 count 매개변수가 범위를 벗어났지만, 제 생각에는 매우 짜증나는 일입니다(내가 시도한 모든 것이 > 1이 범위를 벗어났습니다...)
출력은 dmesg다음에서 끝납니다.
