목표는 SSD를 다시 작동시키는 것입니다. GParted를 사용하여 포맷하려고 했으나 "/dev/sdc에 쓰는 동안 입력/출력 오류가 발생했습니다"라는 메시지가 표시되었습니다. GParted로 확인하면 다음과 같은 결과가 나타납니다. 무엇 향후 계획?
GParted 0.25.0 --enable-libparted-dmraid --enable-online-resize

이 값은 SMART 예측 실패 표시에서 한 단계 떨어져 있습니다. 인터넷상의 이 값에 대한 설명이 정확하다면 SSD의 최악의 칩에는 사용할 수 없는 것으로 표시된 블록이 87개 있다는 의미입니다. 속성 #179와 비교하면 이 칩은 지금까지 예비 부품으로 교체된 전체 불량 블록의 거의 3분의 1을 차지합니다.
(내가 아는 한 RAW_VALUE는 실제 값이고 VALUE는 배율 조정된 값이며 더 클수록 좋습니다. 속성이 더 이상 해당 THRESHold 값보다 높지 않으면 사전 실패 SMART 오류가 발생합니다.)
또한 쓰기 작업 중에 오류가 표시된다는 사실은 dmesg이 SSD가 제대로 작동하지 않음을 나타냅니다. 기술적으로는 아직 죽지 않았을 수도 있지만, 멀지는 않을 수도 있습니다.
