无法用hdparm获得正确的SATA drive状态

湖里的鱼

在kernel 2.6.11（已经打过libata-dev patch)，使用hdpram -C /dev/sda检测SATA drive power mode status,返回的结果一直是standby，实际上SATA drive是active mode,使用smarttools正常。Log如下：

# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby
#
# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby
# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby

# ./hdparm -S 60 /dev/sda

/dev/sda:
setting standby to 60 (5 minutes)
# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby
# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby
# ./hdparm -C /dev/sda

/dev/sda:
drive state is:  standby
#

# ./smartctl -i -d ata /dev/sda

那位大侠有这方面的经验啊,指点一下！！

druggo

hdparm不支持sata的硬盘啊

KDE

ml 2.0 根本没有使用这样的内核，你是用的什么发行版？
