This version of the Windows and GPT FAQ applies to Windows 1. Windows Server 2. For a previous version of this FAQ, see Windows and GPT FAQ on MSDN. Since the introduction of the personal computer, the data storage area on a hard disk has been divided into smaller areas called sectors. These sectors are grouped into partitions creating separate volumes, or drives on a disk. The partitions were organized using a scheme called the Master Boot Record MBR. The MBR is a table of disk locations, or addresses, along with a certain length, of each of the partitions present on the disk. The MBR itself occupies a small amount of the disk and is read during the boot phase to determine where to locate the operating system to boot into. The MBR information is also used by the operating system as a map of the volumes present on the disk. Eventually, data density for disks became too large for the MBR scheme to account for all the available data locations. Also, the layout, or format, of the MBR was designed for early computers and not flexible enough to accommodate newer disk configurations. A new partitioning method was needed so the GUID Partition Table GPT partitioning scheme was created. GPTWhat is a GPT disk The GUID Partition Table GPT was introduced as part of the Unified Extensible Firmware Interface UEFI initiative. GPT provides a more flexible mechanism for partitioning disks than the older Master Boot Record MBR partitioning scheme that was common to PCs. A partition is a contiguous space of storage on a physical or logical disk that functions as if it were a physically separate disk. Partitions are visible to the system firmware and the installed operating systems. Access to a partition is controlled by the system firmware before the system boots the operating system, and then by the operating system after it is started. What is wrong with MBR partitioning MBR disks support only four partition table entries. For more than four partitions, a secondary structure known as an extended partition is necessary. Extended partitions can then be subdivided into one or more logical disks. Windows creates MBR disk partitions and logical drives on cylinder boundaries based on the reported geometry, although this information no longer has any relationship to the physical characteristics of the hardware disk driver or RAID controller. Starting with Windows Vista and Windows Server 2. Serial Number Monopoly Game House. Because this partition information is stored on the drive itself, the operating system is not dependent on the alignment. Im Internet tauchen immer wieder Berichte und Fragen zu einem Windows PE Preinstalled Environment auf. Wir mchten mit diesem Artikel kurz erklren, um was es. Microsoft Windows Xp Oem Preinstallation Kit Opk' title='Microsoft Windows Xp Oem Preinstallation Kit Opk' />MBR partitioning rules are complex and poorly specified. For example, does cylinder alignment mean that each partition must be at least one cylinder in length An MBR partition is identified by a two byte field, and coordination is necessary to avoid collision. IBM originally provided that coordination, but today there is no single authoritative list of partition identifiers. Another common practice is using partitioned or hidden sectors to hold specific information by using undocumented processes and results in problems that are difficult to debug. In the past, vendor specific implementations and tools were released to the public, which made support difficult. Why do we need GPT GPT disks allow for growth. The number of partitions on a GPT disk isnt constrained by temporary schemes such as container partitions as defined by the MBR Extended Boot Record EBR. The GPT disk partition format is well defined and fully self identifying. Data critical to platform operation is located in partitions and not in unpartitioned or hidden sectors. GPT disks use primary and backup partition tables for redundancy and CRC3. The GPT partition format uses version number and size fields for future expansion. Each GPT partition has a unique identification GUID and a partition content type, so no coordination is necessary to prevent partition identifier collision. Each GPT partition has a 3. Unicode name. This means that any software can present a human readable name for the partition without any additional understanding of the partition. Where can I find the specification for GPT disk partitioning Chapter 5 of the Unified Extensible Firmware Interface UEFI specification version 2. GPT format. This specification is available at http www. What is the GPT format for basic disks Basic disks are the most commonly used storage types with Windows. Basic disk refers to a disk that contains partitions, such as primary partitions and logical drives, usually formatted with a file system to become a volume for file storage. The protective MBR area on a GPT partition table exists for backward compatibility with disk management utilities that operate on MBR. The GPT header defines the range of logical block addresses that are usable by partition entries. The GPT header also defines its location on the disk, its GUID, and a 3. CRC3. 2 checksum that is used to verify the integrity of the GPT header. Each entry in the GUID partition table begins with a partition type GUID. The 1. 6 byte partition type GUID, which is similar to a System ID in the partition table of an MBR disk, identifies the type of data that the partition contains and identifies how the partition is used, for example, whether it is a basic disk or a dynamic disk. Note that each GUID partition entry has a backup copy. For more information about basic disks, see Basic and Dynamic Disks. What is the GPT format for dynamic disks Dynamic disks were first introduced with Windows 2. RAID 5 volumes. Dynamic disks can use the MBR or GPT partition styles on systems that support both. For more information about dynamic disks, see Basic and Dynamic Disks. Is UEFI required for a GPT disk No. GPT disks are self identifying. All the information needed to interpret the partitioning scheme of a GPT disk is completely contained in structures in specified locations on the physical media. How big can a GPT disk be In theory, a GPT disk can be up to 26. Logical blocks are commonly 5. The maximum partition and disk size depends on the operating system version. Windows XP and the original release of Windows Server 2. TB per physical disk, including all partitions. For Windows Server 2. SP1, Windows XP x. Windows file systems currently are limited to 2. How many partitions can a GPT disk have The specification allows an almost unlimited number of partitions. However, the Windows implementation restricts this to 1. The number of partitions is limited by the amount of space reserved for partition entries in the GPT. Can a disk be both GPT and MBR No. However, all GPT disks contain a Protective MBR. What is a Protective MBR The Protective MBR, beginning in sector 0, precedes the GPT partition table on the disk. The MBR contains one type 0x. EE partition that spans the disk. Why does the GPT have a Protective MBR The Protective MBR protects GPT disks from previously released MBR disk tools such as Microsoft MS DOS FDISK or Microsoft Windows NT Disk Administrator. These tools are not aware of GPT and dont know how to properly access a GPT disk. Legacy software that does not know about GPT interprets only the Protected MBR when it accesses a GPT disk. These tools will view a GPT disk as having a single encompassing possibly unrecognized partition by interpreting the Protected MBR, rather than mistaking the disk for one that is unpartitioned.
