不幸的是我不明白它想要告诉我什么。
- 什么是
ata7.00？ - 是什么
failed command: SEND FPDMA QUEUED意思？这是什么FPDMA？ - 这是什么
device reported invalid CHS sector 0意思？
我怀疑这与驱动器有关，但我不知道如何调试也不知道如何解决这个问题。

sdg是通过 PCIe 卡连接的 mSATA SSD。sda-sdf是带有 ZFS 的 SATA HDD。
驱动器的详细信息：
sdaWD Red 8T，主板 SATA 连接器。sdbWD Red 8T，主板 SATA 连接器。sdcWD Red 8T，主板 SATA 连接器。sddWD Red 8T，主板 SATA 连接器。sdeWD Red 4T，主板 SATA 连接器。sdfWD Red 8T，主板 SATA 连接器。sdg三星 mSATA 1T，由三星便携式 SSD T5 分离而成，通过 PCIe 卡连接。nvme0n1以及nvme1n1三星 970 EVO，连接到主板m.2连接器。
系统未显示其他错误迹象。此外，除日志中的这些错误外，一切似乎都按预期运行。
答案1
笔记：最好先做好备份。
您需要检查/升级三星 SSD 上的 sdg 和 nvme* 固件。
前往三星的下载页面这里并下载他们的 Samsung Magician 软件工具来帮助升级固件。其他软件更新也在那里提供。
还要检查 sdg PCIe 卡的固件升级。
使用 检查主板 BIOS sudo dmidecode -s bios-version。然后访问制造商的网站并查找较新的 BIOS。如果有，请下载并安装。
笔记：稍后，如果仍然有问题，我们将讨论 ncq 补丁。
