我希望这是一个提出此类问题的正确地点。
这是否表明我的这个驱动器有问题？它有点新，并且在退货期限内。我运行smartctl -t long /dev/sdb并等待了一夜。今天我运行时看到了这个smartctl -a /dev/sdb：

我可以重新运行智能扫描，但这几乎花了一整天的时间，所以如果这表明有问题，我宁愿提前处理。谢谢！
答案1
标签#14 检测密钥：非法请求 [当前]
标签#14 添加检测：未对齐的写入命令
Sense Keys 是存储目标生成的消息。这些消息表明服务器已成功向目标提交 IO 请求，但目标拒绝了该 IO 请求并显示错误消息。
导致此类错误的原因有很多。在 Github 错误报告中 返回“未对齐的写入命令”错误#10094，原因包括磁盘坏、电缆坏、主板不兼容、甚至是主板坏。
我的建议是不要犹豫：新磁盘有问题或不兼容，所以最简单的解决方案是退货。如果其他制造商的另一个磁盘也出现类似错误，你应该检查硬件是否有问题。
