我有一台华硕笔记本电脑，已经用了 5 年了，从来没有出过问题。几周后，它的响应速度不如往常，昨天我格式化并重新分区了硬盘，并用压缩空气吹干了笔记本电脑，以清除里面的灰尘。在安装 Windows 7 SP2 时，我听到硬盘发出轻微的咔嗒声，几个小时后，我试图通过复制大量文件来重现这种声音，但无法做到。我知道这种声音通常意味着有麻烦，所以我联系了 GSmartControl。进行了测试，我看到一些指示器显示“预故障”。我真的不懂 SMART 术语之类的，但我应该担心吗？以下是 GSmartControl 对我的硬盘的评价：

我已经有一个完整备份，但我真的不想遇到任何意外。根据 GSmartControl 的说法，我是否需要更换笔记本电脑的硬盘？感谢您的关注。
答案1
我从来都不喜欢用压缩空气清洁设备，因为它实际上只会将灰尘推到其他地方，而这些地方的灰尘可能会更加有害。我认为最好使用吸尘器，因为它可以有效清除灰尘。
如果你的笔记本电脑太旧了，升级硬盘是个好主意。如果你安装一个固态硬盘，它会比刚买的时候好得多。
