本文档详细记录了在Linux系统中如何查看硬盘信息，并将新的硬盘分区挂载到/data目录的过程。首先使用fdisk命令检查磁盘情况，创建新的分区，然后格式化为ext3文件系统，最后创建/data目录并将其永久挂载。

Disk /dev/sdb doesn't contain a valid partition table
[root@ZJIDCInterface1 ~]# fdisk /dev/sdb
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 6527.
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)
