LINUX下新硬盘挂载

关于新硬盘的挂载主要有几个步奏：（我用的是Ubuntu9.10）
一.首先查看自己的设备，用命令 fdisk -l
   youlong@ubuntu:~$ sudo 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: 0x000c4e91
   Device Boot      Start         End      Blocks   Id  System
  /dev/sda1   *           1        1243     9984366   83  Linux
  /dev/sda2            1244        1305      498015    5  Extended
  /dev/sda5            1244        1305      497983+  82  Linux swap / Solaris
  Disk /dev/sdb: 5368 MB, 5368709120 bytes
  255 heads, 63 sectors/track, 652 cylinders
  Units = cylinders of 16065 * 512 = 8225280 bytes
  Disk identifier: 0x00000000
  (其中sdb是新添硬盘)
二.对新硬盘进行分区，用命令fdisk /dec/sdb
   eg:
   [root@linux ~] sudo fdisk /dev/sdb             "sdb为新添硬盘"
   youlong@ubuntu:~$ sudo 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 0x784f9b03.
   Changes will remain in memory only, until you decide to write them.
   After that, of course, the previous content won't be recoverable.
