一、过程步骤
1、安装硬盘（过程略）。
2、fdisk -l查看硬盘代号。
3、fdisk分区格式化
4、创建新的挂载点：/disk2
5、手动挂载分区。
6、设置为开机自动挂载分区。
二、开工
2、
查看硬盘代号
[root@AMD-LINUX ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0007d856

/dev/sda1 * 1 25 200781 83 Linux
/dev/sda2 26 1305 10281600 8e Linux LVM
Disk /dev/sdb: 2147 MB, 2147483648 bytes <=新硬盘
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Disk /dev/sdb doesn't contain a valid partition table
Disk /dev/dm-0: 9395 MB, 9395240960 bytes
255 heads, 63 sectors/track, 1142 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x30307800
Disk /dev/dm-1 doesn't contain a valid partition table
3、fdisk 分区
[root@AMD-LINUX ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x623223a1.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

4、创建挂载点
[root@AMD-LINUX ~]# mkdir /disk2
[root@AMD-LINUX ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0007d856
Device Boot Start End Blocks Id System
/dev/sda1 * 1 25 200781 83 Linux
/dev/sda2 26 1305 10281600 8e Linux LVM
Disk /dev/sdb: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x623223a1
Device Boot Start End Blocks Id System
/dev/sdb1 1 261 2096451 83 Linux
Disk /dev/dm-0: 9395 MB, 9395240960 bytes
255 heads, 63 sectors/track, 1142 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x30307800
Disk /dev/dm-1 doesn't contain a valid partition table
[root@AMD-LINUX ~]# mke2fs -j /dev/sdb1

5、格式化分区
mkfs -t ext3 /dev/sdb1
6、设置为开机自动挂载分区
[root@AMD-LINUX ~]# vi /etc/fstab
/dev/sdb1 /disk2 ext3 defaults 0 0
然后执行 mount -a
或者手动挂载分区
[root@AMD-LINUX ~]# mount /dev/sdb1 /disk2
