您当前的位置: 昨天就给U盘里面存了一些资料，今天使用的时候发现只要对U盘做删除，剪切，写入操作，explorer进程就会崩溃，但是数据可以读出来，而且没有被破坏，格式化提示“格式化未成功”，尝试了U盘量产工具，结果还是没弄好，在Ubuntu下，系统自动挂在后，只要做在windows相同的动作，U盘会被自动卸载，使用
mount -t vfat /dev/sda1 /mnt
命令对其挂载，提示如下错误
- C/C++ code
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
系统日志中可能有一些重要的信息，
试试用 dmesg | tail 之类的命令查看。
使用dmesg命令查看，发现如下错误
- C/C++ code

求硬件高手解释一下出这个错误的原因
