== An Overview of GPT and MBR Partition Styles ==

Before a Windows Server 2008 R2 system disk can be mirrored it is important to identify the partition style used by the disk as this will dictate the technique used to create the mirror. In order for a disk to be used to store data it must first have partitions created on it. These partitions are then formatted with a particular file system (FAT, FAT32 or NTFS) and used either as a basic disk or as dynamic disk. Obviously, the operating system needs some mechanism for organizing and managing these disk partitions and Windows Server 2008 R2 provides two such partitioning styles known as Master Boot Record (MBR) or GUID Partition Table (GPT).
