Linux下格式化U盘为NTFS格式
思路，删除原有windows的fat分区，新建主分区，格式化为ntfs：

备注：
1，最好在终端界面，即Terminal(Ctrl+Alt+F1,F2,F3)界面下执行；
2，有时候会遭遇“设备或资源忙“的情况， 一般是因为系统开启了autofs服务，即自动挂载服务，需要临时手动停止一下：
???? sudo /etc/init.d/autofs stop
3，如果是图形化界面（比如centos的gnome下），需要在系统菜单下的首选项里的可移动驱动器和介质，在“可移动存储里”去掉前三行的复选框（热插拔时挂载可移动驱动器、插入时挂载可移动介质、插入时浏览可移动介质），这样就不会出现IO设备或资源忙的错误了。
