硬盘电源管理给出了一些技巧，使硬盘在不必要的时候不工作，而且还能减少噪音。
A few different tricks prevent your hard drive from working unnecessarily often in Disk Power Management (decreasing noise level as a nice side effect).
由于嵌入式系统中电池电量是有限的，而硬盘功耗比较大，驱动提供了硬盘电源管理的接口，用以降低系统的整体功耗。
Besides, as the battery in the embedded system is limited and the power consumption of hard disk is high, a simple power management strategy is presented to reduce the system power consumption.
这样的一种架构通常只包含单个硬盘、单个光纤通道适配器或单个电源供所有设备共用。
Such an architecture would include a single hard disk, a single Fibre Channel adapter, or a single power source for any piece of equipment.
几个组织称他们经历过其他原因导致的停用，比如硬盘故障、电源故障和网络故障。
Several organizations reported that they had experienced outages due to other causes, such as hardware failures, power outages, and network disruptions.
记住，硬盘、风扇和电源都是计算机中可物理移动的部件，因此它们最有可能需要替换。
Remember that hard disks, fans, and power supplies are the parts in your computer that physically move, making them the most likely to require replacement.
确保插紧电缆，对连接硬盘驱动器和计算机电源的电力电缆也要进行检查。
Make sure it is plugged in tightly and also check the power cable that connects the hard drives to the computer’s power supply.
当你打开一个文件，它不断地保存在内存中，但对于光盘，硬盘，当你断开电源的时候，数据不会丢失。
When you're working on a file, it's saving constantly to RAM but also hopefully to disc, the hard disk so you don't actually lose it if the power goes off.
断开电源就相当于将硬盘格式化了一样。
Turn off the power to these drives and you might as well have reformatted them.

In this case the contents of the memory are written to the hard drive and the system is powered off.
在Other 类别中还有另外几个传感器，包括电池、硬盘和电源指示器。
There are several additional sensors grouped into the Other classification, including battery, hard disk, and power supply indicators.
一个解决办法是使用UPS，当电源掉电时，给系统足够得时间以便把缓存(也包括系统缓存)中的数据写到硬盘盘片上。
Adding a UPS to the system allows enough time to flush the drive cache (and potentially the system caches) solving the problem.
如果你能够从大容量的闪存缓存读取数据，而不是转动硬盘，就可以大大节省电源。
If you could get data from a large flash memory cache instead of spinning up the hard drive, you'd save a lot of power.
如果你能够从大容量的闪存缓存读取数据，而不是转动硬盘，就可以大大节省电源。
