一個關於hdparm參數的錯誤【求助】

[autok]

[root@autok root]# hdparm -m16 -c3 -d1 -X69 /dev/hda

/dev/hda:
setting 32-bit I/O support flag to 3
setting multcount to 16
setting using_dma to 1 (on)

錯誤訊息--> HDIO_SET_DMA failed: Operation not permitted

setting xfermode to 69 (UltraDMA mode5)
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
using_dma = 0 (off)

我有hda1,5,6
和hdb1,5,6,7
還有我的硬碟廠牌是hda=WD
hdb=Maxtor

請問一下是那裡出問題了....謝謝

不要下X69 看看 !!

也試試看-c3改成-c1
