저는 최근 스토리지용으로 새로운 SATA 1TB Seagate Barracuda 하드 드라이브를 설치했습니다. 최근에 드라이브에서 "읽기"하는 데 1~2분, 운이 좋다면 수십 초 정도 지연되는 문제가 발생했습니다. 미디어를 시청하면 프로그램이 중단되고 ls해당 디렉토리에서 실행이 지연되며 게임 플레이가 중단됩니다.
문제(SATA 연결 실패/커널 문제)를 진단하려면 어떻게 해야 합니까? 최근에 잘못된 종료로 인해 일부 디렉터리가 손상된 후 드라이브에서 e2fsck를 실행했습니다. 일부 사용자는 드라이브 상태를 확인하기 위해 SMART로 시작하는 것을 권장합니다. 저는 데비안 스트레치를 사용합니다.

그래서 /var/log/messages를 살펴보고 이것을 발견했습니다. SATA 연결에 결함이 있는 것으로 보이며 커널이 연결을 시작하려고 시도하고 있습니다. 내가 맞나요?
