fdisk -l /dev/sdb가 정지됩니다.

등등. 드라이브에 액세스하려고 할 때마다 액세스하려는 프로세스가 중단되어 액세스할 수 없습니다. 배드 블록을 실행하려고 했는데 20분 후에 작동이 멈췄습니다. 배드 블록이 120초 이상 차단되었습니다.
어떤 종류의 하드웨어 문제로 인해 디스크와 통신하려는 모든 프로세스(모든 진단 도구 포함)가 정지되는지 잘 모르겠습니다. Ctrl-C로 종료할 수 없으므로 터미널을 종료해야 합니다. 어떻게 해야 하나요?

gnome-disks 유틸리티는 디스크의 Ext4 파일 시스템이 손상되지 않았으며 smartctl 테스트에서 "연결 시간 초과"를 반환한다고 말합니다. 그래서 무슨 일이야?

이는 불량 블록이 아직 재배치되지 않았으나 166개 블록이 의심스럽고 원시 읽기 오류 및 수정 불가능한 오류가 발생했음을 나타냅니다.
HDD에서 불량 블록을 수동으로 스캔한 다음 불량 블록을 다시 매핑해야 합니다.
Note: do NOT abort a bad block scan!
Note: do NOT bad block a SSD
Note: backup your important files FIRST!
Note: this will take many hours

안에 terminal...
sudo fdisk -l# 모든 "Linux 파일 시스템" 파티션을 식별합니다.
참고: fdisk작동이 중단 되면 gparted.
sudo e2fsck -fcky /dev/sdXX# 읽기 전용 테스트

-k는 이전 불량 블록 테이블을 저장하고 새 불량 블록을 해당 테이블에 추가하므로 중요합니다. -k를 사용하지 않으면 이전 불량 블록 정보가 모두 손실됩니다.
-fccky 매개변수...
-f Force checking even if the file system seems clean.
-c This option causes e2fsck to use badblocks(8) program to do a
read-only scan of the device in order to find any bad blocks.
If any bad blocks are found, they are added to the bad block
inode to prevent them from being allocated to a file or direc‐
tory. If this option is specified twice, then the bad block
scan will be done using a non-destructive read-write test.
-k When combined with the -c option, any existing bad blocks in the
bad blocks list are preserved, and any new bad blocks found by
running badblocks(8) will be added to the existing bad blocks
list.
-y Assume an answer of `yes' to all questions; allows e2fsck to be
used non-interactively. This option may not be specified at the
same time as the -n or -p options.
