抱歉楼主,现在才来回贴子。mbr磁盘格式只能支持到2tb的磁盘容量(注意是磁盘容量,不是分区容量,Raid可以看作是一个磁盘),而gpt分区可以支持相当大的磁盘。这个是微软原话:
6. How big can a GPT disk be?
In theory, a GPT disk can be up to 2^64 logical blocks in length. Logical blocks are commonly 512 bytes in size.
Themaximum partition (and disk) size is a function of the operating systemversion. Windows XP and the original release of Windows Server 2003have a limit of 2TB per physical disk, including all partitions. For Windows Server 2003 SP1 Windows XP x64 edition, and later versions, the maximum raw partition of 18 exabytes can be supported. (Windows filesystems currently are limited to 256 terabytes each.)
所以XP 32位的话只支持MBR,或者是GPT的一个叫Protective MBR部分,也就是GPT磁盘的前2TB空间。
Vista和Windows 2003可以支持GPT的读写,在基于EFI的系统上还可以进行gpt磁盘的启动。
而XP 32bit只能使用前2tb空间,XP 64bit只能读写GPT磁盘,而不能从gpt磁盘启动
