这个问题已经在这里有了答案:
- 我的硬盘即将出现故障吗? 3个答案
大约一周前,我的Windows 7 PC在无法使用之前,在一两天内逐渐变慢。当试图执行最平凡的任务(例如浏览网络)时,一切都会冻结。当我尝试运行病毒扫描时,我注意到读/写速度确实很慢,与在隐藏驱动器上删除/传输文件时的读/写速度一样。
我随后认为可能是硬盘驱动器问题,但是尽管如此,我还是尝试了全新的操作系统安装,并且一切正常。几天后,突然一切都重新锁定了我。有一次它无法启动,启动了Windows启动恢复(我不记得确切的名称-因为Windows无法启动而启动),它本身无法启动,向我显示了一个黑白屏幕,说磁盘可能出现故障。
此后,我已经运行了Ubuntu Live CD,并在硬盘上运行了SMART扫描,但是我不确定如何提取结果(请参见下文)。关于故障前和Old_age的信息很多,所以我认为是时候购买一个新的硬盘了,但是如果有人可以确切地告诉我此信息的含义以及我是否正确,我将非常感激。
