1、打开终端,查看系统日志文件:

tail -f /var/log/syslog

2、插入优盘。

3、系统文集syslog输出以下内容:

Feb  :: noi dbus-daemon[]: [session uid= pid=] Successfully activated service 'org.gnome.Shell.HotplugSniffer'
Feb :: noi kernel: [ 328.500293] FAT-fs (sdc1): error, corrupted directory (invalid entries)
Feb :: noi kernel: [ 328.500299] FAT-fs (sdc1): Filesystem has been set read-only
Feb :: noi kernel: [ 328.631504] FAT-fs (sdc1): error, corrupted directory (invalid entries)

4、说明优盘识别为:sdc1,并且出现错误。

5、先写在优盘:

umount    /media/jack/UUI

6、用dosfsck工具修复以下:

sudo  dosfsck -v -a /dev/sdc1

7、完工。注意不能输入/dev/sdc,通常都需要挂一个数字。
