내 하드 드라이브의 일부에 액세스할 수 없고 마운트되지 않은 것 같습니다. 크기를 줄이면 이런 일이 발생합니다

저는 Samsung SSD 850 EVO M.2 250GB 하드 드라이브가 내장된 Intel NUC에서 Linux Mint serena를 사용하고 있습니다.

컴퓨터 아래에서 파일 시스템과 Samsung SSD 850 EVO M.2 250GB라는 드라이브를 찾았습니다. 하드 드라이브의 이 부분은 접근할 수 없고, 내가 아는 한 설치되지 않았으며, 크기는 약 20GB입니다.

해당 영역은 드라이브 아래에 나열되어 있지만 sda3다른 곳에는 나열되어 있지 않습니다. 크기를 줄이거나 마운트할 수도 있나요?

sda3의 크기를 줄이면 어떻게 되나요? 이를 달성하기 위해 swapon 명령을 어떻게 사용할 수 있습니까? 자유 명령의 출력:
