硬盘是计算机的主要外部存储设备 ,计算机的运行速度 ,在很大程度上取决于硬盘的存取速度。在硬盘的使用中 ,如果设置不当 ,随着系统运行时间的增加 ,磁盘碎片会越来越多 ,从而造成系统运行效率的下降 ,同时还可能造成用户数据文件的损失。本文介绍的方法 ,可有效地解决磁盘碎片的问题 ,并在因系统故障需格式化系统分区时 ,可防止造成用户数据的损失 Hard disk is the computer’s main external storage device, the computer’s speed, largely depends on the hard disk access speed. In the use of the hard disk, if improperly set, as the system uptime, disk fragmentation will be more and more, resulting in decreased system operating efficiency, but also may result in the loss of user data files. This article describes the method that can effectively solve the problem of disk fragmentation, and in case of system failure to format the system partition, to prevent the loss of user data
