我在透過 USB 3.0 連接的 ICY BOX IB-368STU3-B 盒子中有一塊 Western Digital 綠色 2TB SATA 磁碟。
在某個時刻，磁碟不再可用（並且盒子背面的藍色 LED 關閉）。
查看 dmesg 日誌：

我把它換成另一個盒子（相同但是新的），效果相同。
我把裡面的DD換成了希捷Green 2TB，效果一樣。
我在 2 個 USB3 連接埠、2 個 USB2 連接埠、另一台筆記型電腦、Ubuntu（目前運行我的筆記型電腦的發行版）、Debian stable（測試另一個核心）和 Sysrescue 上進行了測試，效果相同。
第一次，當我rsync對其進行操作時它停止了，因此它處於活動狀態（我在其上複製了 1TB 資料），突然間，我收到錯誤Input/Output errors並且 /dev/sdc1 不再存在。
知道它可能是什麼嗎？
謝謝您的幫忙！
此致，
拉夫

好吧，我想說，根據這些訊息，它看起來像是一個壞的 USB 控制器，但如果您在多個控制器中測試過它，就可以排除這種情況。另外兩種可能性是電纜和外殼。嘗試使用另一條電纜，如果可以，請將驅動器從 USB 外殼中取出，然後將其直接連接到 SATA 連接埠。
