Large Capacity Drives:
Meeting the technological challenges of 3 TB SATA hard drive implementation.
WD leads the way now offering a massive 3 TBs of storage capacity on a single drive. In a typical PC configuration, a drive may be connected as a primary boot drive, or as a secondary drive. Large capacity drives are no different, however, it is important to verify your system can support a large capacity drive before attempting to install it.
When installed as a boot drive, put simply, the operating system boots off of the drive, (an operating system is required to start the computer). When installed as a secondary drive will solely be used to house data, (the drive will not contain an operating system). While newer systems are set up to handle large capacity drives, older legacy systems require updating and still may not support booting of older operating systems.
To understand if your system will support a hard drive with greater than 2.19 TB, consult your OS, Motherboard and USB bridge device solution providers from the list below before you attempt to install in your system.

|Mac OS 10.5 Leopard||Mac OS 10.6 Snow Leopard||Linux|
1 To achieve full capacity and functionality with drives greater than 2.19 TB, WD requires the use of Microsoft Windows 7 Service Pack 1 (SP1) or later.
2 Presently WD does not directly provide support for these applications. We have worked extensively with our partners and solutions may be available. HBA and RAID Controller vendors may have developed solutions for these applications.
3 Boot support requires a system with UEFI Support and a 64-bit version of the OS.
4 Apple Bootcamp is presently not supported. Support is limited to the operating system only.
5 Linux solutions are available. Please consult your Operating System provider for use with Large Capacity drives.
Industry Advances Make Large Capacity Drives Possible
There are several advances in the industry that make large capacity drives possible:
Use Larger Sector Sizes
One way to break the 2.19 TB boundary would be to use a larger sector size and keep the number of addressable blocks the same. By using sector sizes of 4096 (4K) bytes this would allow for systems to address a maximum capacity of 232 x 4096 bytes or 17.59 TB. Unfortunately, WD has determined through testing that is not feasible at this time due to many application incompatibilities with devices using sector sizes above 512 bytes. However, hard drive manufacturers are working with industry partners to implement larger native sector sizes in the future.
WD has transitioned to using sector sizes of 4096 bytes or a 4 KB physical sector size on some hard drive models; this is referred to Advanced Format (AF) technology. Although the drive may be using a sector size of 4096 bytes to store data on the media, it reports and emulates a disk using 512 bytes to avoid application incompatibilities.
Use GPT Instead of MBR
The solution adopted by the industry is to use GUID Partition Tables, otherwise known as GPT, instead of Master Boot Record (MBR) partition tables. UEFI is a community effort by many companies in the computer industry to modernize the booting process. This partitioning method provides for up to 18 Exabyte (264) of Logical Block Addressing. UEFI capable systems are already shipping, and many more are in preparation. Booting a current Windows operating system from a drive larger than 2.19 TB requires that the system have UEFI support, a 64-bit version of the OS and will create and use GPT partitions.
The UEFI specification defines a new model for the interface between operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications.
Implement WD's Interim Solutions for Implementing Large Capacity Drives
Existing legacy (non-UEFI) BIOS motherboards and GPT-ready operating systems such as Windows Vista or Windows 7, combined with the appropriate storage class drivers, can use drives larger than 2.19 TB as secondary storage; but there are a number of host bus adapter (HBA) and chipset vendors that do not currently offer drivers that support drives larger than 2.19 TB. To provide a solution for these types of compatibility issues, WD originally bundled large capacity WD Caviar® Green™ 2.5 TB and 3 TB drives with an AHCI-compliant HBA that, once installed, allowed the operating system to use a known driver to correctly support large capacity drives. This bundle provided a short-term solution until the time when updated storage drivers and system software with support for large capacity drives were available.
Updated storage drivers and system software are now available from several major vendors removing the need for the HBA. WD is now releasing a new version of the 2.5 TB and 3 TB with a SATA 6 Gb/s interface that do not include the HBA.
Illustrative Example: Should an end user decide to add a secondary drive to an existing desktop computer system that incorporates a chipset such as an Intel-based chipset on a legacy (non-UEFI) motherboard running an operating system such as Windows, the 3rd party storage class driver may not properly support a drive larger than 2.19 TB. If the large capacity drive is attached directly to the native motherboard SATA controller, the 3rd party driver may attach to the drive and the driver will not recognize the drive's full capacity, resulting in an incompatibility issue. An attempt to uninstall the driver could render the whole system inoperable.
How You Can Take Advantage of Large Capacity Drives
WD provides many options that you can use to take advantage of large capacity drives, even on current computer system configurations with today's technologies.
- Impelemeting a large capacity WD drive as the system start up drive will require a system with UEFI support and will use GPT partitions (see table)
- Implementing a large capacity WD drive in legacy systems will enable using the large capacity drive as secondary storage and will use GPT partitions.
Review the considerations for Windows-based operating systems above to help determine what options are available for implementing large capacity drives on your current systems, and to help you plan future operating system and computer system purchasing plans.
Considerations for Audio-Video (AV) Devices
AV products are diverse in their applications and the use of storage products. With WD now offering hard drives with massive capacity up to 3 TBs for AV applications it is important to verify whether specific AV products can support a large capacity drive before attempting installation.
Most products that use storage have some type of operating system and system start up software that needs to take into account the size and the impact that size may have on the different layers of software contained within their products. Older systems using legacy operating systems and BIOSs that utilize the Master Boot Record (MBR) partition table scheme encounter a barrier at 2.19 TB.

What does Advanced Formatting mean to me?
Advanced formatting optimizes hard drives to take advantage of the capabilities of newer operating systems. This capability enables hard disk drive manufacturers the ability to design larger capacity hard drives, now and into the future.
What are the benefits of Advanced Formatting?
Advanced Formatting enables hard drive companies to read and write more data into the same available space on the hard drive.
Can I install an Advanced Format hard drive in my system?
New drives from WD are optimized for operation with Windows 7, Windows Vista and Mac OS X Tiger, Leopard, Snow Leopard. If you are attempting a clean install of an Advanced Format hard drive into a system running one of the Operating Systems listed above the installation process follows standard procedure. For older operating systems such as Windows XP, and for users using cloning software, users must run the WD Align utility to achieve the full performance of the drive. (See table for configuration details)
Early 3.5-inch WD drives with Advanced Format supported jumper pins 7 – 8. Placing a jumper on these pins adjusted the drive’s internal alignment for single partition XP installations. Support for this jumper setting is no longer needed on newer drives. For optimal performance on all XP installations WD recommends running the WD Align utility.
If you have a drive that supports jumper pins 7 – 8 and have a jumper in place on those pins, the following is additional information to assist you if you are re-installing an Operating System or re-partitioning the drive:
- IMPORTANT: You must backup your drive before making any changes, including removal of the jumper.
- Re-partition the drive: Turn off power to the drive and remove the jumper from pins 7 – 8. Power-on and re-partition the drive (NOTE: All previous data on the drive will be lost).
- Preserve Current Partition: If you are installing an Operating System over the existing partition, keep the jumper on pins 7 – 8. The drive is already aligned to the existing partition so you do not need to remove the jumper.
- If you change the setting of jumper 7 – 8, you will lose all previous data and the drive must be re-partitioned.
For a clean install of Windows XP using multiple partitions, DO NOT install the jumper; simply run the WD Align utility.
Can I install a WD Advanced Format Drive under non-Windows Operating Systems, such as MacOS and Linux?
WD Advanced Format Drives can be used under non-Windows Operating Systems.
Do I need a special driver to install a WD Advanced Format Drive on an Intel chipset?
If your operating system is either Windows 7 or Vista, we recommend the following for maximum performance in all situations:
- For Intel chipset, use the latest Intel driver version 9.6 or later. Please visit Intel for the latest driver downloads at http://www.intel.com/support/chipsets/imsm/sb/CS-031502.htm
- For AMD chipset, no driver update is required.
- For Nvidia chipset, please visit http://support.microsoft.com/kb/982018 for additional information.
What is WD Align utility software?
The WD Align utility enables older operating systems to operate at full performance on Advanced Format hard drives.
How long will running the WD Align utility take?
It will vary based on your operating system and how much data is on the disk, but the WD Align utility should take about 20 minutes to complete on freshly installed drive images with no data files. We recommend disabling Power Management prior to starting the partitioning alignment process.
Does the WD Align utility have to be run again if a drive is reformatted?
No, users will only need to run WD Align one time after initially installing Windows XP. Once Windows XP has been aligned, it will stay aligned even if the drive is reformatted or many files are added or removed.
What models utilize Advanced Format technology?
Some models of the WD Green and WD Blue product families are built using Advanced Format technology. Over time more models and capacities will be added. WD drives with Advanced Format technology include special installation information on the drive label so be sure to read the label on your drive before installing it.
Does WD Align work with Western Digital USB and Firewire drives, such as My Book and My Passport drives?
If you do not change the partitions on a Western Digital USB or Firewire drive, the drive is already optimally aligned. However, all Western Digital USB and Firewire drives are specifically designed to work with WD Align. If you repartition a Western Digital USB or Firewire drive, WD Align should be run to optimally align the partition or partitions.
Can I install my Advanced Format Drive into a USB enclosure?
