Therefore, a reference to Windows 7 includes Windows Server 2008 R2, Windows Vista includes Windows Server 2008, and Windows XP includes Windows Server 2003 and Windows Server 2003 R2.

The operating system-specific behavior that is noted in this article also applies to the server variants of that system.

Therefore, references to 2 TB actually refer to a product that is labeled as having 2.2 TB of capacity.

This article refers to disk capacity in powers of two instead of powers of 10, which is the more common designation on storage device capacity labels.

It also describes the requirements to address the full storage capability of these devices. This article outlines Microsoft support across all Windows versions since Windows XP. If the user intends to start the computer from one of these large disks, the system's base firmware interface must use the Unified Extensible Firmware Interface (UEFI) and not BIOS. This scheme supports addressing of the full range of storage capacity. In order for an operating system to fully support storage devices that have capacities that exceed 2 terabytes (2 TB, or 2 trillion bytes), the device must be initialized by using the GUID Partition Table (GPT) partitioning scheme. This article discusses the manner in which Windows supports hard disks that have a storage capacity of more than 2 TB and explains how to initialize and partition disks to maximize space usage.Īpplies to: Windows Server 2019, Windows Server 2016, Windows Server 2012 R2 Original KB number: 2581408 Summary
