我的笔记本电脑在DOS下无法分区？
每次输入FDISK后进入到：Your computer has a disk larger than 512 MB. This version of Windows includes improved support for large disks, resulting in more efficient use of disk space on large drives, and allowing disks over 2 GB to be formatted as a single drive.
IMPORTANT: If you enable large disk support and create any new drives on this disk, you will not be able to access the new drive(s) using other operating systems, including some versions of Windows 95 and Windows NT, as well as earlier versions of Windows and MS-DOS. In addition, disk utilities that were not designed explicitly for the FAT32 file system will not be able to work with this disk. If you need to access this disk with other operating systems or older disk utilities, do not enable large drive support.
Do you wish to enable large disk support (Y/N)...........? [Y]
再点[Y]时就回到A：盘符下，而无法在下一步分区了怎麽办？
参考答案:把你的笔记本型号报出来，有些笔记本是不能分区（使用常用工具）的，只有返厂分区。
这一款本本，用户是可以分区，只不过是麻烦点，就是因为联想设了隐藏分区，又怕用户自己分区而破坏隐藏分区里面的内容，所以针对常用分区软件进行了一些改动。不过还是有办法的，你用原版XP光盘自带工具删除所有原来分区，然后继续用它分区、格式化，这样就可以解决问题了。
注：如果只是重装系统，建议用联想的一键恢复来恢复系统（前提是隐藏分区没有被破坏）。
