在之前的命令列表上面看到，n代表创建新硬盘分区，那么接下我们输入n命令来创建新分区：
root@figo:/home/feigo# fdisk /dev/sdb

Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-976773167, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-976773167, default 976773167):
Using default value 976773167

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.
完成，再查看，已经发现多了一个sdb1的分区：
root@figo:/home/feigo# fdisk -l

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
81 heads, 63 sectors/track, 191411 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

3. 格式化分区为ext4：

root@figo:/home/feigo# mkfs.ext4 /dev/sdb1
mke2fs 1.42.5 (29-Jul-2012)
文件系统标签=
OS type: Linux
块大小=4096 (log=2)
分块大小=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
30531584 inodes, 122096390 blocks
6104819 blocks (5.00%) reserved for the super user
第一个数据块=0
Maximum filesystem blocks=4294967296
3727 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

102400000

Allocating group tables: 完成
正在写入inode表: 完成
Creating journal (32768 blocks): 完成
Writing superblocks and filesystem accounting information: 完成
格式化完成，可以使用parted命令查看/dev/sdb的分区格式：
root@figo:/home/feigo# parted
GNU Parted 2.3
Using /dev/sda
