又有新问题了，这些空间哪里去了？(已解决)

Gentoo ~ # fdisk /dev/sda

The number of cylinders for this disk is set to 19457.
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)

我在windows的磁盘管理中也看到有将近3.6g的未分配空间但是不可操作？这是为什么？好像也搜不到答案:help

print the partition table, then let's see what happened.

我以前使用不同的分区工具操作磁盘时出现过这种状况，当时是由于各分区的几何特征不同造成的，不知道你是否属于这种状况。

sda3,sda5,sda6上次作成LVM，未修改为8e标记。我粗略加了一下是要加上那3.6g才约等于硬盘149g左右

One harddisk contains at most 4 primary partitions (including Extend partition), but it can have many logic partitions (must be Extend partition).
In your table, sda1-3 are 3 primary partitions, sda4 is a Extend partition. So no more space for additional primary partition.
You must add the new partition on Extend partition if the Extend partition has extra empty space.

thanks!确实是这样，我以前分该分区为主分区的，后来又调整了一下分区就这样。现在我已经用norton pqmagic蒋其调整为扩展分区？不过扩展分区扇区却不连贯了。。。
