跟着图文教程到分区，就不一样了求助啊，急求！

[root@AY140208215018Z ~]# fdisk -l


Disk /dev/hda: 21.4 GB, 21474836480 bytes
224 heads, 56 sectors/track, 3343 cylinders
Units = cylinders of 12544 * 512 = 6422528 bytes


   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        3343    20967268   83  Linux


然后分区
[root@AY140208215018Z ~]# fdisk -S 56 /dev/hda
然后出现下面。
