闪存盘问题

我的 U 盘有问题，我需要其中的数据，但是……：

  1. lsusb（几分钟后就再也看不到它了）：

    总线 002 设备 023：ID 0951：1642 金士顿科技 DT101 G2

  2. dmesg | grep sd-> 没有看到，所以我只使用了dmesg：

  3. fdisk也没看到

  4. 我用 petrol 清洁了 pendrive - 它可以工作（Windows 8 已经看到了它 - 但是它的驱动程序存在问题...）

答案1

根据dmesg摘录，列表中的设备消失lsusb，以及 Windows 报告的驱动程序问题，您的 USB 驱动器已彻底损坏。优秀的数据恢复技术人员可能能够挽救其中的数据，因为通常只有 USB 接口芯片损坏，而不是闪存或其控制器。
