1、

查看磁盘情况：

fdisk -l

信息如下：

[root@CentOS6 ~]# 

如果看不到U盘的话，尝试 加载USB模块 "modprobe usb-storage" 。

2、

创建一个文件夹"/mnt/usb_zz"

3、

挂载U盘：

mount -t vfat /dev/sdb1 /mnt/usb_zz

ZC：(1)、这里，没有"-t vfat"的话，会提示 指定文件系统。(2)、fat32 的文件系统 对应的参数就是 vfat。

4、

卸载U盘

umount /mnt/usb_zz

执行umount命令卸载U盘时，报如下错误“device is busy”，

可以用参数l解决问题:(ZC: 这里是小写的字母L)

　　umount -f /mnt/usb_zz

　　umount -l /mnt/usb_zz

也可以用fuser命令解决问题。
