我的笔记本电脑安装了 Windows 10 秋季创意者更新（一周前安装），主磁盘为 SSD OCZ Vertex 128GB + 辅助内置磁盘为 Samsung SSD 512GB，后者替代了 DVD 驱动器，使用合适的托架（DELL Latitude E6520）。
今天，重新启动后突然无法访问辅助磁盘，而该单元在 Windows 资源管理器中可见，显示正确的已用数据量和可用空间，但是尝试访问该单元会引发错误“由于 I/O 设备错误，无法执行请求”；尝试 CHKDSK 会指出文件系统为 RAW。
我运行了 SMART 测试，得到了以下附加结果。然后我运行了 Easus 恢复工具，发现了很多文件，但不是全部。我非常担心，我访问了同时恢复的磁盘。返回 NTFS，完全可访问，CHKDSK 没有给出任何错误。
我不知道为什么会发生这一切，以及该单位是否可靠。
你的想法？
编辑：
发现很多这样的文章就像这个指出这种突然变化可能是由于连接不良或断电而发生的。我想知道我是否可以依赖这个磁盘和计算机本身
编辑2：
问题再次出现。下载了 Samsung Magician，设备上未检测到任何错误，我怀疑问题出在控制器或操作系统上。我已拔下硬盘盒并取出硬盘，将其连接到外部 USB 电缆。目前正在测试。我想知道内部控制器是否会出现故障？
编辑3：
现在是第二天，磁盘通过 USB 电缆连接到外部。没有故障，还有一个重要方面：笔记本电脑键盘在过去几个月里停止工作，必须关闭电脑电源然后再打开才能使其恢复工作。自从我从磁盘盒中取出磁盘后，这种情况就不再发生了。可能是磁盘盒有故障？还是控制器有故障？或者可能是内部磁盘消耗了控制器的太多能量？

答案1
如果您珍视自己的数据，请停止使用该驱动器。几年前，我曾使用过一个这样的驱动器，它随机开始出现文件系统损坏。仔细检查后，我发现它似乎在随机将一个扇区的内容重新分配到另一个扇区，导致我的部分文本文件出现在本应是目录条目的地方。在我停止使用该驱动器之前，这种情况发生过几次。
我不会再相信 OCZ 来保管我的数据了。
