硬盘负责PC系统的数据存储,一般来说只要我们打开电脑,硬盘就始终处于读写状态直到我们彻底关机。由于工作频率太高,硬盘也是PC系统当中比较容易出问题的一个,尤其是HDD由于内部存在物理运动,损坏的几率更高(图13)。其实硬盘的问题并非只要出现就等于无法使用,很多硬盘出问题前甚至出问题时的症状都很轻微,并不影响使用。但是如果不加以防范任其进一步发展,可能最终会导致盘体损坏数据丢失的惨剧。一般来说PC异常断电或关机、磁盘突然产生噪音,都需要特别关照一下硬盘是否会产生问题。如何在硬盘刚开始出现问题甚至是即将出现问题之前发现隐患,是我们需要掌握的。
The hard disk is responsible for the data storage of the PC system. In general, as long as we turn on the computer, the hard disk is always in a read-write state until we completely shut down. As the operating frequency is too high, the hard disk is also one of the more problematic ones in the PC system. In particular, HDDs are more likely to be damaged due to internal physical movement (Figure 13). In fact, the problem of the hard disk is not as long as it can not be used, even before the hard drive problems even when the symptoms are very mild, does not affect the use. But if you do not prevent any further development, may eventually lead to disk damage data loss tragedy. In general, PC abnormal power failure or shutdown, the disk suddenly produce noise, need special attention to whether the hard disk will have problems. How to detect the hidden trouble before the hard disk starts to appear or even the imminent problem is what we need to master.
