我有 Transcend 的 240 GB 便携式 SSD。
- ESD230C 便携式固态硬盘
- 模型：
TS240GESD230C - 序列号：F43849-0038
最近读取数据出现长时间延迟的情况。在另一次如此长的延迟期间，我不安全地断开了设备。之后，一个大约2GB大小的文件从我的磁盘上消失了。我试图通过找到丢失的文件文件系统实用程序在测试盘，但文件丢失了。
然后我尝试使用最重要的是:

经过几次重新连接后，磁盘完全停止正确连接。它没有安装。更糟糕的是，它的大小现在显示为 1023 MB。我还尝试将驱动器连接到另一台笔记本电脑，它也显示大约 1 GB 的大小。

我还能尝试用它做什么？
假设：
也许我可以切换一些模式？也许有一些具有最低功能的安全模式，但它允许我读取磁盘？例如，尝试在 USB 1/2/3 模式下工作？或者尝试其他一些驱动程序？
如果磁盘的大小不真实，是否有可能以某种方式向系统指示实际大小并仍然尝试读取数据。比如指定磁盘大小为200GB，强制它从磁盘中逐字节读取信息，直到读完为止？
不幸的是，我对磁盘以前的结构知之甚少。但我仍然有启动日志文托伊，也许我可以以某种方式恢复分区。
