The number of cylinders for this disk is set to 32635.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

接下來是啓用swap space:
[YOUHUA-WR1200JS /home/root]#mkswap /dev/sda1
Setting up swapspace version 1, size = 255996416 bytes
系統下次啓動的時候會調用U盤的swap作爲緩存


====以上完成分区设置SWAP，以及格式化====
U盘替代移动硬盘，很小巧，速度还可以，而且不用考虑用电的问题。

啓用ENTware
首先，創建OPT目錄，輸入命令  mkdir /media/Main/opt

然後在路由器管理界面進行以下圖片標註的設置。


最後查看掛載是否成功，正常掛載顯示如下：
[YOUHUA-WR1200JS /opt/home/admin]# mount
