U 디스크 파티션이 사라지고 마운트할 수 없습니다.

USB 파티션은 삭제되고 sdb만 남습니다. sdb1이 존재하지 않습니다. USB를 다시 파티션하는 방법은 무엇입니까? 이제 출력에 표시되지만 lsblk설치할 수 없습니다.

[xx@x ~]$ lsblk

[xx@x ~]$ sudo fdisk /dev/sdb

Welcome to fdisk (util-linux 2.39).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

작동하는 USB를 연결하고 sudo fdisk /dev/sdb 명령을 실행하면 사용할 수 있는 명령이 나타납니다. 예를 들어 이 m명령이 작동합니다.

n 명령을 사용하지 마십시오. fdisk /dev/sdb 실행시 잠시 후 입출력 오류가 발생합니다.

fdisk: cannot open /dev/sdb: Input/Output error
