最近，我决定重新开始使用 Linux Mint，安装后不久，我发现硬盘性能严重下降。我电脑中的辅助驱动器存在性能问题。（主驱动器上安装 Windows，辅助驱动器上安装 Linux。）桌面需要近 5 分钟才能完全开始响应并正常工作。我决定查看硬盘的 SMART 数据以确定驱动器是否出现故障，但似乎没有问题。我甚至进行了广泛的自检，它似乎运行正常。
我决定切换回 Windows，以为这是 Linux 相关的问题，但令我惊讶的是，驱动器的性能同样糟糕。报告显示磁盘使用率为 100%，但传输速度仅为 300 kb/s。
在安装 Linux 之前，驱动器运行正常。
我现在不知道该做什么。任何帮助我都会非常感激。
注意：这是 Seagate 硬盘，因此“Raw_Read_Error_Rate”不正确。

我最近将驱动器写入零，格式化，重新分区，甚至将分区与驱动器上的扇区对齐。它仍然非常慢。我现在的速度是 10 MB/s，而不是额定的 150 Mb/s。
我唯一能说的是，我运行了 Steam 并安装了一些游戏，然后它又开始了。即使重启后它仍然继续发生。等待 15-30 分钟后它似乎消失了……
有人，任何人……请帮帮我。它使启动时间超过 8 分钟，我无法打开任何东西。我再也无法使用我的电脑了……
