하나 구매했어요Seagate Backup Plus 5TB USB 3.0 휴대용 2.5인치드라이브, 최근에 1TB 드라이브가 부족해서 ArchLinuxARM을 실행하는 RPi2에 연결했고 집에서 음악을 들을 수 있습니다(감사합니다)스냅 사진).
저는 기본 데스크탑/서버(젠투 실행)에서 아무런 문제 없이 기본 Micro$oft 드라이브를 ext4로 포맷했습니다. "-m 0" 옵션을 사용할 때 장치의 루트 공간을 예약하기 위해 의도적으로 생략했습니다.
mkfs.ext4 -m 0 /dev/sdg1
...완료되면 rsync를 사용하여 추출된 모든 음악과 비디오를 Seagate 드라이브에 복사한 다음 RPi2에 연결합니다.
RPi2가 장치를 감지하고 이를 마운트한다고 주장하지만 장치에서 아무것도 읽을 수 없으며 df에서도 감지되지 않습니다.

...그래서 장치가 올바르게 설치되지 않는 이유가 약간 혼란스럽습니다. 무엇을 조사하거나 시도해야 하는지에 대한 조언이나 조언을 주시면 감사하겠습니다.
