我有一个西部数字绿色2TB SATA磁盘在一个冰盒IB-368 STU3-B盒连接通过USB 3.0连接。
在某个时刻，磁盘不再可用了(盒子背面的蓝色LED也关闭了)。
见dmesg日志：

[427082.940172] sd 2:0:0:0: Device offlined - not ready after error recovery我换了另一个盒子(同样的，但一个新的)，同样的效果。
我用一个希捷绿2TB改变了它的DD，同样的效果。
我在2个USB3端口、2个USB2端口、另一个笔记本电脑、Ubuntu (当前运行我的笔记本电脑的发行版)、Debian (测试另一个内核)和Sys救援上进行了测试，效果相同。
第一次，当我在上面做rsync时，它停止了，所以它在活动中(我在上面复制了1TB的数据)，突然间，我收到了错误Input/Output errors和/dev/sdc1 1不再存在了。
知道会是什么吗？
谢谢你的帮助！
诚挚的问候,
拉斐尔

我会说，基于这些消息，它看起来像是一个糟糕的usb控制器，但是如果你已经在多个控制器中测试过它，这就排除了这种可能性。另外两种可能性是电缆和外壳。尝试另一个电缆，如果可以的话，从usb外壳中取出驱动器，并将其直接连接到sata端口。
