我刚刚在一台机器上安装了几个新的HDD，但我偶然发现其中一个报告了两个错误，因此我smartctl -x在其上运行并得到了以下信息：

如您所见，驱动器的开机时间为520（这是准确的，因为我已经用了不到一个月的时间），但是这两个错误表示它们分别在10610小时和16878小时发生-显然是不可能的。
这里发生了什么事？ 错误是真的吗？令人担忧吗？我的供应商会在这里进行某种“里程表篡改”吗？
更新资料
（我早就知道了，但是HGST Western Digital :/确实无济于事（如果他们根本不保留任何有关它们的信息，为什么要给OEM驱动器序列号？），而且响应速度也很慢。）
当我安装这些标签时，我注意到它们的标签上没有像以前那样的标签上的生产日期，但我只是想让制造商不要再打印它们了，于是再也没有想到……我看到了Deltik的好答案。 在我看来，这些并没有（或可以有效地消除）。
在尝试从制造商（新所有者）那里获得官方认可的尝试失败后，我将它们全部拉开，并以最大设置将平板扫描仪对准了他们。通过进行旧的缩放和增强，我能够发现每一个被擦除的证据。这是一个易于阅读的示例：
（原谅5717×8117px，64.0MB .png宽恕）
精简的.jpg概述：
犯罪现场的原始分辨率为.png（标签的右上角）：
那些眼神敏锐的人也许已经可以阅读它，但这是一个自动级别的矩形：
是的。所有这些驱动器都有这种故意欺骗的痕迹，它们都是从2015年3月/ 4月/ 5月开始的。在2018年11月底，“新”含义还不完全。
此外，就像其他评论者一样，我很震惊SMART可以被这样颠覆。如果可以重设，它的大部分要点是否就没有了？
我会进一步追求的，相信我。关注此空间。

16.8万小时的时间是否与标签上的生产日期一致？还是该错误来自驱动器制造之前？

@PeterCordes，现在我们可以看到他们尝试隐藏的日期，它们确实是一致的。
