"새" 드라이브를 구입했지만(백업 저장소의 드라이브는 사용하지 않음) 몇 가지 smartctl 테스트를 수행한 후 이상한 점을 발견했습니다.

짧은 자체 점검 후에 숫자 3이 나타났습니다. 수명(시간)의 차이는 무엇을 의미합니까?

답변1
기존 드라이브의 SMART 값이 0으로 재설정된 것 같습니다.
일부 Windows 프로그램은 자체 테스트 로그를 표시하지 않으며 Linux에서도 일부 사람들은 -H 또는 -A(사용 가능한 경우)만 확인하므로 이를 놓칩니다.
어느 쪽이든 이 드라이브는 새로운 것이 아닙니다. 결함이 있거나 섹터가 0으로 재설정되었음에도 불구하고 재할당되었을 수도 있습니다.
중요한 데이터가 포함된 드라이브를 신뢰하지 마십시오.
