输入命令：df -h后发现：

大概有1T 的空间，但是我的电脑可是有2T＋125G固态硬盘呢，还有没用到的，于是再次执行：sudo fidisk -l
发现：

最后一步就是设定开机自动挂载，
如下：
输入命令：sudo blkid
$ sudo blkid
/dev/sdb1: UUID="52313c6f-a18d-4088-baf8-f44b647c8947" TYPE="ext3"
/dev/sda1: UUID="9f6f6ae7-c446-4b61-a61f-c6b8162bc591" TYPE="ext4"
/dev/sda5: UUID="47685248-5732-4766-9d3d-b4b4602472c4" TYPE="swap"
/dev/sdc1: UUID="7d1eb697-8daa-4f29-bafa-e65a70cdab35" TYPE="ext3"
/dev/sdc3: UUID="7d1eb697-8daa-4f29-bafa-e65a70cdab35" TYPE="ext3"
最后别忘记改一下权限：
sudo chmod 777 /home/chaihuasong/1T
sudo chmod 777 /home/chaihuasong/SSD
OK,大功告成，正在重启电脑。。。
发现如下配置不需要：
sudo vim /etc/fstab
加入如下两行：
UUID=52313c6f-a18d-4088-baf8-f44b647c8947 /home/chaihuasong/1T ext4 defaults 1 2
UUID=7d1eb697-8daa-4f29-bafa-e65a70cdab35 /home/chaihuasong/SSD swap sw 0 0
特地更新一下。
