USB 驱动器无法识别

USB 驱动器无法识别

我尝试访问 HAMA Classic USB 3.0 闪存驱动器上的重要文件,但无济于事。昨天工作正常,但现在似乎无法正确识别。

驱动器位于 lsusb 中(此行仅在驱动器插入时可见):

Bus 002 Device 009: ID 058f:6387 Alcor Micro Corp. Flash Drive

但是 sudo fdisk -l 无法识别它,只有:

Device     Boot      Start        End    Sectors   Size Id Type
/dev/sda1  *          2048 1241874431 1241872384 592.2G 83 Linux
/dev/sda2       1241876478 1250263039    8386562     4G  5 Extended
/dev/sda5       1241876480 1250263039    8386560     4G 82 Linux swap / Solaris

lsblk 的输出:

这些是我通过 dmesg 得到的信息:

我还在 Windows 计算机中尝试过 USB 驱动器,也遇到了类似的问题 - 有声音表明它已被识别,但我无法访问文件。如果有人能给我任何关于如何恢复文件的想法,我将不胜感激。
