我遇到了一个奇怪的问题。我有一个 WD Green 3TB 硬盘，它总是报告处于待机状态。30 分钟后，硬盘会自动进入休眠状态（无论我用 hdparm 设置了什么）。但如果我在硬盘休眠或我主动使用它时执行 -C，它总是报告“待机”。
它对以下情况也没有反应：
sudo hdparm -y /dev/sda
它不支持 -C 或 -y 功能吗？如果是，还有其他方法可以将待机时间从 30 分钟缩短到 15 分钟吗？以及/或者能够远程 (ssh) 检查它是否处于待机状态？
以下是有关该驱动器的更多信息：

当我尝试使用 -C 或 -y 时，它确实向我发出错误，但我不确定这个长十六进制字符串是什么意思。据我所知，它必须能够读取驱动器才能获得“驱动器状态为：待机”，否则它不会打印该信息？
sudo hdparm -C /dev/sda
/dev/sda:
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
drive state is: standby
sudo hdparm -y /dev/sda
/dev/sda:
issuing standby command
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
答案1
可能是 WD 的问题。我有一个 WD8003FRYZ，hdparm -C 也总是显示 ›standby‹，尽管驱动器正在旋转。
