Element14 Pi 데스크탑 키트를 사용하여 SSD를 Raspberry Pi 3B+에 연결했습니다. 드라이브는 시작 시 인식 /dev/sda되고 올바르게 마운트되지만 /etc/fstab잠시 후 사라집니다.
(Element14에서는 2.5A 전원 공급 장치가 rpi+SSD에 전원을 공급하기에 충분하다고 주장하지만) 전원 공급 장치가 충분하지 않다는 의심이 들기 시작하여 최대 3.5A를 제공하는 새 전원 공급 장치를 구입했습니다. 내 킬어와트(kill-a-watt)를 통해 아직 확인했습니다. 파이를 다시 시작했고 드라이브는 평소처럼 올바르게 마운트되었지만 약 10시간 후에 다음과 dmesg같이 표시됩니다.

그 이후에는 드라이브가 더 이상 나타나지도 않았습니다 lsblk. 드라이브가 사라진 이유는 무엇입니까?
