fsck error on boot
최근에 fsck를 수동으로 실행해야 하는 경우가 있었습니다 . 그래서 그렇게 했더니 문제가 사라졌습니다. 그 후 실행 smartctl -a /dev/sda
하고 다음 속성을 확인합니다.

무슨 뜻인가요? 이것이 내가 걱정해야 할 일입니까?
다른 유사한 질문을 검색했지만 답변을 찾지 못했습니다. 내 운영 체제는 Ubuntu 20.04입니다.
이것은 smartctl 출력입니다.

이는 드라이브에 마모가 전혀 없으며 여전히 100% 수명이 남아 있음을 나타냅니다.
5%로 떨어지면 당황할 때입니다.

32는 괜찮아 보이지만 61은 좀 높으니 케이스에 통풍이 충분한지 확인하세요.
