손상된 U 디스크가 계속 사라지고 수리 작업을 수행할 수 없습니다.

손상된 USB 플래시 드라이브를 복구하려고 합니다. 이것은 새로운 USB 플래시 드라이브이며 동료가 암호화를 시도한 후 작동이 멈췄습니다. 안타깝게도 암호화가 어떻게 깨졌는지는 알 수 없으나 그 과정에서 중요한 데이터(파티션 테이블 등)가 깨졌을 것으로 추정됩니다.

이를 삽입하면 시스템이 해당 항목을 찾아 및 lsusb의 출력 에 표시합니다 lsblk.

dd그러나 그런 다음 무언가를 실행 하거나 수행 badblocks하려고 하면 mkfs이러한 모든 명령이 결국 I/O 오류로 인해 실패합니다. 이 경우 펜 드라이브는 lsusb또는 의 출력 에도 나타나지 않습니다 lsblk. 그래서 저는 이 과정에서 OS가 어떻게든 펜 드라이브의 연결을 끊었다고 가정합니다.

연결을 유지하려면 어떻게 해야 하나요?
