CentOS 5 - hdparm - DMA 모드 설정 방법

저는 PATA 하드 드라이브를 사용하여 CentOS 5를 실행하고 있습니다. 나는 사용했다HD 매개변수더 나은 성능을 위해 하드 드라이브를 조정했지만 두 가지 설정이 작동하지 않습니다.

hdparm -M 254 /dev/hda

오류가 발생합니다

HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error

그리고

hdparm -d1 /dev/hda

오류가 발생합니다

HDIO_SET_DMA failed: Operation not permitted

이를 설정하려면 무엇을 확인해야 합니까? 이미 오래된 하드웨어이므로 더 많은 성능을 끌어내기 위해 할 수 있는 모든 것이 도움이 될 것입니다.

감사해요.

요청에 따라 hdparm -iI /dev/hda 및 cat /proc/ide/hda/settings의 출력은 다음과 같습니다.

DMA 및 음향 설정이 존재하지만 성공적으로 설정할 수 없습니다. 출력은 다음과 같습니다.

[root@hptest ~]# hdparm -iI /dev/hda
