Question

SONY笔记本电脑，怎么创建新分区？

是SONY的FW27，自带VISTA，开机只有1个C盘
好象本身有个什么压缩卷的方法能创建新分区，但貌似只能再分出来1个盘？
现在想分成4个盘，怎么办呢？
只能用PartitionMagic这样的软件去分吗？

Answer 1

Linux下可以用fdisk命令新建分区，方法如下：
1、首先查看硬盘信息，用fdisk -l命令，如果有硬盘有剩余空间就可以对其进行分区。
[root@bogon 桌面]# fdisk -l
Disk /dev/sda: 85.9 GB, 85899345920 bytes
255 heads, 63 sectors/track, 10443 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000471ad
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 3851 30720000 83 Linux
/dev/sda3 3851 4106 2048000 82 Linux swap / Solaris
/dev/sda4 4106 10444 50912256 5 Extended
/dev/sda5 4106 10444 50911232 83 Linux

Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
#从上面看出/dev/sda空间已经用完了，/dev/sdb没有使用。
2、下面对/dev/sdb 进行分区
[root@bogon 桌面]# 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 0xfaa2aa49.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

Command (m for help): m //输入m查看帮助文档
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 //添加一个新的分区
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)
#fdisk选中/dev/sdb 输入m所有基本选项都出现，输入n新建分区
Command (m for help): n
Command action
e extended
p primary partition (1-4)
3、有扩展分区和主分区，逻辑分区在扩展分区中建立。注意到括号中的1-4，最多只能建四个主分区（包括扩展分区）。先建一个主分区：
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p #建主分区
Partition number (1-4): 1 #分区号为1
First cylinder (1-2610, default 1): #直接回车默认从第一个柱面开始划分
Using default value 1
Last
cylinder, +cylinders or +size{K,M,G} (1-2610, default 2610): +2G
#加空间大小，这里有很多种选择：+后面单位可以接M，G，K（记得要大写）表示划分你所加的空间，也可以是柱面数。不管怎样都不能超过该磁盘剩余的空间否则无效。

Command (m for help): p #分好后查看分区信息，刚所做的所有一目了然。
Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xfaa2aa49

Device Boot Start End Blocks Id System
/dev/sdb1 1 262 2104483+ 83 Linux
4、同上所述建立扩展分区：

Command (m for help): n
Command action
e extended
p primary partition (1-4)
e #建立扩展分区
Partition number (1-4): 4
First cylinder (263-2610, default 263):
Using default value 263
Last cylinder, +cylinders or +size{K,M,G} (263-2610, default 2610): +4G

Command (m for help): p

Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xfaa2aa49

Device Boot Start End Blocks Id System
/dev/sdb1 1 262 2104483+ 83 Linux
/dev/sdb4 263 785 4200997+ 5 Extended
5、扩展分区建好就可以在扩展分区建立逻辑分区了

Command (m for help): n
Command action
l logical (5 or over)
p primary partition (1-4)
l #建逻辑分区
First cylinder (263-785, default 263):
Using default value 263
Last cylinder, +cylinders or +size{K,M,G} (263-785, default 785): +2G

Command (m for help): p

Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xfaa2aa49

Device Boot Start End Blocks Id System
/dev/sdb1 1 262 2104483+ 83 Linux
/dev/sdb4 263 785 4200997+ 5 Extended
/dev/sdb5 263 524 2104483+ 83 Linux
6、上面显示已经建好一个主分区，一个逻辑分区，但是这些现在还没有生效，需要保存退出。

Command (m for help): w #保存退出
The partition table has been altered!

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

Answer 2

压缩卷的方法能分出来3个主分区和若干逻辑分区，但操作不是很方便。最好还是找类似XP中的PQ这样的软件吧。

Answer 3

如果你坚持用你的VISTA，如果你不是一个专业人士，个人建议不要分区

Answer 4

索尼的本本不能用分区软件分
尤其是vista系统分了你的系统就挂了
还是只能用系统自带的压缩卷的方法分最安全
右击我的电脑选择管理-点击左边的磁盘管理-在右边右击c盘选压缩卷-输入可压缩空间
默认就是可用的空间-确定-右击D盘选压缩卷再分-分到不能分为止
这个方法是最简单最安全的了
