所以看起来最近很多 Sandisk Extreme 设备都崩溃了。该公司更新了一些固件，但我的设备似乎不需要任何有关网站自动检查器的更新，但无论如何，我的设备突然崩溃并停止工作，就像其他设备一样。我尝试了不同的端口、不同的电缆和不同的 PC，结果都一样，该设备似乎无法安装。在多次尝试寻求建议但未果后，我带着一些日志来到这里，数据一定在那里，那么在把这个设备扔进垃圾箱之前，我怎样才能访问我的文件？...
该设备显示在 lsusb 命令中：

命令 mount /dev/sdb 指示“在 /dev/sdb 上未找到介质”。
那么我能做什么或尝试哪些选项来访问设备并恢复数据？ 是否有任何物理方法可以尝试访问内部数据？ 比如重新焊接 USB 连接器或 PCB 上的某些东西（我猜如果在 lsusb 中读取了 ID，那么设备连接器应该没问题……）？
在此先感谢任何能帮助我的人
