최근 외장 하드 드라이브를 바닥에 떨어뜨렸는데, 전자 부품과 기계 부품이 손상되었는지 궁금합니다. smartctl의 출력에서 이것을 찾는 방법을 모르겠습니다. 사용하면서 내장 SSD도 테스트해보고 싶었습니다. sudo smartctl -t short내부 SSD와 외부 하드 드라이브를 실행했습니다 . 온라인으로 검색했지만 대부분의 가치가 나에게 제공되지 않았으며 내 가치가 무엇이 중요하고 그것이 무엇을 의미하는지에 대한 정보가 거의 또는 전혀 없다는 것을 알았습니다.
질문:중요한 가치는 무엇이며 이를 어떻게 해석하며 SSD 및 하드 드라이브에 대한 결론은 무엇입니까?
값이 100(0 = 최악, 100 = 최고)으로 정규화되어 있다고 읽었습니다. 이를 고려하면 SSD의 경우 하드 드라이브, Load_Cycle_Count 및 Free_Fall_Sensor의 온도 값이 더 낮습니다. 하지만 이 중 어떤 것도 실제로 우려되는 부분인지는 잘 모르겠습니다.
그건 그렇고, 두 가지 모두 백업이 있지만 자주는 아니기 때문에 상황을 평가하고 싶었습니다.
