我有一个非常奇怪的问题。我有一个格式化为 FAT32 的闪存驱动器。我将一个文件复制到闪存驱动器并将其借给一位朋友，他将其插入他的 Windows PC。电脑无法识别该驱动器，因此我将其拔出并再次插入我的电脑。令我惊讶的是，它不知何故被损坏了。插入时它不会自动安装。以下是迄今为止我尝试过的所有信息和内容：
dmesg输出似乎并不罕见：

lsblk输出（与 sdc 相关）是：
sdc 8:32 1 14,7G 0 disk
└─sdc1 8:33 1 14,7G 0 part
sudo fdisk -l输出（与 sdc 相关）是：
Disk /dev/sdc: 14,7 GiB, 15744892928 bytes, 30751744 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x52febbce
Device Boot Start End Sectors Size Id Type
/dev/sdc1 2048 30750719 30748672 14,7G b W95 FAT32
sudo mount /dev/sdc1 flashdrive/给出错误：
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
sudo mount -t vfat /dev/sdc1 flashdrive/给出相同的结果。
我也尝试过sudo fsck.vfat /dev/sdc1，但出现错误
fsck.fat 3.0.28 (2015-05-16)
Logical sector size (138 bytes) is not a multiple of the physical sector size.
最后，我尝试了 gparted 程序。信息关于 /dev/sdc1 是
Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sdc1 is missing
我还尝试了 gparted 功能尝试数据救援，但它无法恢复任何东西。
所以，就是这样。我还没有重新格式化闪存驱动器，希望有办法避免丢失所有数据。有什么建议么？
