Linux下用GHOST来做系统备份(4)

原来是这里的Extended 已经将最后的结束柱面指定为1106了,只要修改成8924应该就可以找回丢失的容量

,原因找到了,马上动手。

,也可以继续进行细分,看个人需要了)

注意对应的Blocks的大小是否与母盘一致!!
Command (m for help ) :w             (保存并退出)
 
5.6建立新分区的文件系统:
       mkfs –t ext3 /dev/sda7     (小心操作,一定要注意是不是你所要建立的分区)
5.7建立新分区卷标:
       tune2fs –L/store /dev/sda7  (卷标自己根据需要定)
5.8加载新分区
       mkdir /store
       mount –t ext3 /dev/sda7 /store
