我的筆記型電腦配備 Windows 10 Fall Creators Update（一周前安裝），其主磁碟 SSD OCZ Vertex 128GB + 輔助內部磁碟 Samsung SSD 512GB，後者作為 DVD 驅動器的替代品，使用合適的托盤（戴爾Latitude E6520） 。
今天，重新啟動後突然無法存取輔助磁碟，而該裝置在 Windows 資源管理器中可見，顯示正確的已使用資料量和可用空間，但是嘗試存取該裝置會拋出錯誤「要求由於I/O 裝置錯誤而無法執行」；嘗試 CHKDSK 會表示檔案系統是 RAW。
我已經執行 SMART 測試，得到以下附加結果。然後我運行了 Easus 恢復工具，發現了很多文件，但不是全部。非常擔心我訪問了同時恢復的磁碟。回到 NTFS，完全可以訪問，沒有 CHKDSK 給出的錯誤。
我想知道為什麼會發生這一切，以及裝置是否可靠。
你的想法？
編輯：
發現很多這樣的文章正如這個指出這種突然的變化可能是由於連接不良或斷電而發生的。我想知道我是否可以依賴這張磁碟和電腦本身
編輯2：
問題又出現了。下載了三星魔術師，在裝置上沒有偵測到錯誤，我懷疑問題出在控制器或作業系統。我已經拔掉了托盤的插頭並取出了硬碟，將其連接到外部 USB 電纜。目前正在測試中。請問是否會出現內部控制器損壞的狀況？
編輯3：
現在是第 2 天，磁碟透過 USB 連接線連接到外部。沒有任何故障，還有另一個重要方面：筆記型電腦鍵盤在過去幾個月停止工作，必須關閉並打開電腦電源才能將其恢復工作。由於我已從磁碟盒中取出磁碟，因此這種情況不再發生。球童會不會有缺陷？還是控制器？或者內部磁碟可能從控制器消耗了太多能量？

答案1
如果您重視數據，請停止使用該驅動器。幾年前，我遇到了其中一個，隨機開始引發檔案系統損壞。仔細檢查後，它似乎隨機地將一個扇區的內容重新分配給另一個扇區，導致我的一些文字檔案的部分內容出現在本應是目錄條目的內部。在我停止使用該驅動器之前，這種情況發生了好幾次。
我不會再信任 OCZ 處理我的資料。
