USB 2.0 포트가 외장 하드 드라이브를 인식하지 못합니다.

하나 샀어요Seagate FreeAgent GoFlex Desk 2TB 외장 하드 드라이브2년 전 이 드라이브는 Ubuntu와 Windows(듀얼 부팅 워크스테이션)를 실행하는 데 사용되었습니다.

지난주에 Ubuntu가 설치된 다른 컴퓨터를 사용하여 드라이브를 백업했습니다. 드라이브가 USB 2.0 포트에 연결되어 있습니다. 이것은 훌륭하게 작동합니다. 오늘 새 백업을 만들려고 했는데 노트북과 워크스테이션에서 Ubuntu를 사용하는 USB 2.0 포트에서 드라이브가 인식되지 않았습니다. 그러나 USB 3.0 포트를 사용하는 Ubuntu를 사용하는 워크스테이션과 USB 2.0 포트를 사용하는 Windows를 사용하는 워크스테이션에서는 제대로 작동합니다.
