랩탑에서 인식되는 USB 스틱이 있지만 마운트 가능한 파티션이 없습니다. 장치가 /dev/에 나열되어 있지만 sdb파티션이 없습니다 /dev/sdb1. fdisk -l또한 에 대해서는 아무것도 표시하지 않습니다 /dev/sdb. 또한 파티션 테이블을 다시 읽어보았지만 partprobe소용이 없었습니다. 커널을 업데이트하지 않고 재부팅했지만 결과는 여전히 동일했습니다.
나는 또한 이 질문을 발견했습니다:인식할 수 없는 USB 드라이브 마운트여기에 대한 답변으로 해결되었습니다.아치리눅스 포럼, 하지만 내 것이 비어 있기 때문에 이것들은 나에게 도움이 되지 않습니다 /etc/udev/rules.d/.

스틱이 죽어가는 것 같아서 나중에 복원할 수 있도록 데이터를 백업해 두고 싶습니다. 나는 이것을 찾았다USB 스틱의 비트 동일한 이미지를 어떻게 생성합니까?
그래서 나는 다음을 실행했습니다.
sudo dd if=/dev/sdb of=~/usb.img bs=4M
결과 :
dd: failed to open ‘/dev/sdb’: No medium found
저도 같은 방법으로 시도했는데 ddrescue결과는 같았습니다.
ddrescue: Can't open input file: No medium found
그렇다면 내 장치의 데이터에 액세스하거나 최소한 저장하는 방법을 알고 있나요? 도와주셔서 감사합니다!

lsblk오늘 저는 요청의 결과를 댓글로 게시하고 싶었는데, 제 스틱이 원래 이 질문을 했을 때와 다른 동작을 보이고 있습니다.
dmesg다음을 표시합니다.
