我正在尝试附加Mediasonic HFR2-SU3S2到我的 ubuntu 机器。它包含四个 WD Red 3TB NAS 驱动器，采用 RAID5 结构。以下是我将驱动器插入 USB 端口时 dmesg -w 的输出。

说实话，我不确定我在这里读到的是什么。几个月前，这个设备在 Windows 上运行良好（我不再安装 Windows）。我的下一步故障排除步骤应该是什么？任何帮助都将不胜感激！
答案1
今天早上我设法让机箱正常工作。我只是将其中一个驱动器拉出并放回原位。机箱检测到驱动器已被更换并开始重建。这花了几个小时，似乎已经解决了问题。 我不建议其他人这样做，除非他们准备丢失数据。 我没有失去任何东西，但如果出了问题，我可能会失去任何东西。
