那些遇到过的问题

根据SMART硬盘没有坏，但我在dmesg中有错误

use*_*447 13 hard-disk smart

有时我在启动我的计算机（运行 Debian）时遇到奇怪的麻烦。所以我发出了“dmesg”命令。在它的输出中，我看到了很多错误。但是，当我在硬盘上运行扩展 SMART 测试时（使用“smartctl -t long /dev/sda”命令），结果是我的磁盘没有损坏。

这些错误的原因是什么？

以下是错误：

首先，请记住，SMART 说您的驱动器是健康的并不一定意味着驱动器是健康的。SMART 报告是一种帮助，而不是绝对的真理。

如果您感兴趣的只是做什么，而不是为什么，那么请随意向下滚动到最后几段；但是，临时文本将告诉您为什么我认为我的建议是正确的行动方案，以及如何从您发布的内容中得出这一点。

话虽如此，让我们看看这些错误之一告诉我们什么。

（我希望我得到了应该放在一起的部分，但你得到了一堆，所以不管怎样都应该没问题。）

在Linux的ATA Wiki有解释如何阅读这些错误页面。特别，

  • 一个status有价值的DRDY手段“设备准备就绪。正常情况下1，当一切都OK。” 看到状态值为DRDY是完全正常和预期的。
  • SError 有多个组件值，您可以看到其中的值（在此特定代码段中）：
    • UnrecovData “发生数据完整性错误，接口未恢复”
    • HostInt “主机总线适配器内部错误”
    • 10B8B “发生 10b 到 8b 解码错误”
    • BadCRC “发生链路层 CRC 错误”

10b8b 编码将 8 位编码为 10 位以帮助信号同步和错误检测，用于物理布线，不一定用于驱动器本身。驱动器最有可能使用其他形式的 FEC 或 ECC 编码，并且那里的错误通常会显示为某种形式的 I/O 错误，其error值可能为UNC（“无法纠正的错误 - 通常是由于磁盘上的坏扇区”） , 可能在行尾的括号中带有“媒体错误”（“软件检测到媒体错误”）res。后者不是您所看到的，因此虽然我们不能完全排除它，但似乎不太可能。

“链路层”是驱动器自己的控制器和磁盘驱动器接口芯片（可能是计算机主板上南桥的一部分，但可能位于板外 HBA 上）之间的物理电缆和电路板走线。

主机总线适配器，也称为 HBA，是连接到存储设备的电路。也通俗地称为“磁盘控制器”，这个术语在现代系统中有点用词不当。HBA 最明显的部分通常是连接端口，现在最常见的是 SATA 或某些 SAS 外形规格。

在UnrecovData和HostInt标志基本上告诉我们，“一些刚去可怕的错误，并且没有办法恢复或恢复没有尝试”。相反的可能是RecovData，这表明“发生了数据完整性错误，但接口已恢复”。（顺便说一句，我可能会使用HBAInt代替HostInt，因为“主机”指的是 HBA，而不是整个系统。）

的组合10B8B和BadCRC，这都指向物理链路层，让我怀疑是电缆的问题。

这种怀疑也得到了以下事实的支持，即除了状态报告之外，完全在驱动器内部的 SMART 自检没有发现制造商认为严重到足以保证在结果中报告的错误。如果驱动器在存储或读取数据时出现问题，特别是长时间的 SMART 自检应该会报告该问题。

特尔；博士：

因此，我要做的第一件事就是拔掉并重新插入两端的 SATA 电缆；它可能会稍微松动，导致它间歇性地失去电接触。看看是否能解决问题。甚至可能对计算机中的所有 SATA 电缆执行此操作，而不仅仅是受影响的磁盘。如果您使用的是板外 HBA，我也会移除并重新安装该卡，主要是因为当您已经在搞乱布线时，这很容易尝试。

如果失败，请尝试丢弃并更换 SATA 电缆，最好使用高质量的电缆。高质量的电缆会稍微贵一些，但我发现如果它有助于避免像这样的头痛，那么花一点点额外费用通常是值得的。没有人喜欢看到他们的存储喷涌错误！

  • 我拔下并重新插入 SATA 电缆，它解决了问题。谢谢！ (2认同)
