    • A power-saving method adapted in a hard disk in a computer system having a CPU and a memory module is provided. The power-saving method comprises the following steps. A data-to-be-written is transferred from the memory module through the CPU to the hard disk filter. A determining module is provided to determine whether a data access frequency of the computer system exceeds a threshold value. When the data access frequency exceeds the threshold value, the determining module further determines whether a request-queuing time exceeds an idle-mode activation time. When the request-queuing time exceeds the idle-mode activation time interval, the data-to-be-written is stored in a temporary storage location by the hard disk filter. When a condition of the computer system is satisfied, the data-to-be-written is written to the hard disk to extend the duration of an idle-mode of the hard disk. A power-saving operating system is disclosed herein as well.
    • 提供了一种适用于具有CPU和存储器模块的计算机系统中的硬盘中的省电方法。 省电方法包括以下步骤。 要写入的数据通过CPU从内存模块传输到硬盘过滤器。 提供确定模块以确定计算机系统的数据访问频率是否超过阈值。 当数据访问频率超过阈值时,确定模块还确定请求排队时间是否超过空闲模式激活时间。 当请求排队时间超过空闲模式激活时间间隔时,被写入的数据由硬盘过滤器存储在临时存储位置。 当满足计算机系统的条件时,要写入的数据被写入硬盘以延长硬盘的空闲模式的持续时间。 本文还公开了省电操作系统。
