我从三星 S8+ 中取出 microSD，将所有图片复制到 Windows 电脑上。复制过程中出现错误，系统最终冻结，然后出现 BSOD。进行了硬重启，将 SD 卡放回系统，再次出现 BSOD。因此，我将 microSD 移回 S8，但它无法识别它，也无法安装它。我将其取出并插入 Linux 系统。它无法安装，甚至无法显示在各种列表中（df、lsusb 等）。我可以看到设备上有活动（如下面的输出所示），但仅此而已。
我希望能够恢复 microSD 上的数据，但如果 Windows 或 Linux 无法识别要安装的驱动器，我不确定该怎么做。看起来，只要它作为 SCSI 可移动设备连接，USB 就会断开连接。有没有办法防止 USB 断开连接？我不知道这是否会允许我对设备进行原始访问。还有其他建议吗？

您可以尝试使用名为 testdisk 的工具恢复数据，但在使用之前请务必阅读文档，因为如果您操作错误，它可能会损坏您的其他驱动器。
