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~~~
