此文搭建的NAS不能通過外網訪問，只能以區域網為例。
1. 硬體環境
（1）樹莓派3B
（2）希捷NAS硬碟4T
2.環境搭建
2.1 硬碟分區
（1） 樹莓派外界硬碟時不會自動掛載
（2）查看磁碟信息
（3）分區
新購的NAS硬碟還沒使用過，需進行分區；若直接掛載會出現下面錯誤：
root@raspberrypi:/homeroot@raspberrypi:/home/pimount: /home/pi/seagate_disk0: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error.注意：MBR 分區表類型最大支持2T，對於大於2T的硬碟需要使用GPT分區。fdisk只對mbr分區有效，需使用parted分區
