hdparm: SECURITY_SET_PASS: 입출력 오류

나는 hdparm사용하려고보안 삭제SSD를 권장합니다여기.

지금까지는 해당 가이드의 지침에 따라 모든 것이 잘 작동하고 있지만 이 오류를 해결할 수 없는 것 같습니다.

~ $ sudo hdparm --user-master m --security-set-pass NUL /dev/sda
security_password="NUL"

/dev/sda:
 Issuing SECURITY_SET_PASS command, password="NUL", user=master, mode=high
SECURITY_SET_PASS: Input/output error

제안대로 검색하고 테스트했습니다.여기, 그러나 소용이 없습니다. 이것이 옵션이 아닌 경우 SSD를 완전히 지우려면 어떻게 해야 합니까?

참고: 예, 부팅 시 입력해야 하기 때문에 하드 드라이브 "에" BIOS 암호가 있지만 (내가 아는 한) 디스크 자체에는 연결되어 있지 않습니다.
