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) Command (m for help): <==等待你的输入！
输入 m 后，就会看到底下这些命令介绍
Command (m for help): m <== 输入 m 后，就会看到底下这些命令介绍 Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition <==删除一个partition l list known partition types m print this menu n add a new partition <==新增一个partition o create a new empty DOS partition table p print the partition table <==在屏幕上显示分割表 q quit without saving changes <==不储存离开fdisk程序 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 <==将刚刚的动作写入分割表 x extra functionality (experts only)
离开 fdisk 时按下 q，那么所有的动作都不会生效！相反的， 按下w就是动作生效的意思。
