linux下分区、格式化、挂载新硬盘的详细过程

    公司内网的服务器硬盘空间不足，将新买来的150G硬盘挂载并设置成samba的共享目录，关于samba请参考此文章http://blog.csdn.net/linglongwunv/archive/2010/01/19/5212875.aspx，下面介绍怎样将一块新硬盘分区、格式化、挂载到系统，如适合你请继续阅读。服务器上已经有两块硬盘，所以硬盘为sdc，后面就不做说明了，至于不知道sdc怎么回事的人，先去问问百度大哥再回来接着看。
1、# fdisk -l      查看当前磁盘信息，就会发现最下面显示新加入的硬盘不是有效分区，如下：
Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdc doesn't contain a valid partition table
2、# fdisk /dev/sdc      对新硬盘分区，并根据提示进一步操作
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 182401.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
