Linux建立新的硬碟

fdisk -l
使用fdisk -l列出現有的硬碟~~~

???@???-lubuntu:~$ sudo fdisk -l

有一顆sdb沒有被分割~~~

使用fdisk /dev/sdb分割硬碟

???@???-lubuntu:~$ sudo fdisk /dev/sdb

Command (m for help): m   //輸入m找help
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

Command (m for help): n   //新增partation
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): p   //主要磁碟
Partition number (1-4, default 1): 1
First sector (2048-134217727, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-134217727, default 134217727):
Using default value 134217727

Command (m for help): w   //寫入後離開
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

再看一次，已經分割好了~~~
