[quote="pukakk":5kik3t9t]SMART 기능이 있는 하드디스크는 스스로 진단하지 않나요, 요즘 대부분의 하드디스크가 SMART기능이 있던데요.
SMART 기능이 있는 하드디스크는 회전속도가 느려진다는지 헤드가 여러번 움직여야 된다든지 등등을 체크해서 사용자에게 알려줄겁니다. 우분투에서도 SMART 모니터링을 할 수 있어요.

GUI 환경의 storage device manager도 있었는데, 그거는 이름을 정확하게 모르겠네요.
좋은 하루 되세요 [/quote:5kik3t9t]
정말 좋은 정보 감사합니다. 이런 방법이 다 있었군요.
위 링크를 열어 못하는 영어 실력으로 대충!!! 제 노트북에 설치하고 실행해 보니 이런 메시지가 뜨네요.
(제대로 한 것인지는 모르지만 … )
무슨 뜻인가요? 대충이라도 요약을 …
