System Image Support for Advanced Format Hard Drives on Dell Business Client Notebooks and Desktops


Table of Contents


This article describes Dell™ Notebook and Desktop system image support for Advanced Format hard drives.
It was revised June 2013 and has the latest information available.


What is an Advanced Format Hard Disk Drive?

The Hard Disk Drive (HDD) industry is moving towards supporting Advanced Format (AF) 4k sector hard drives to address the current technological limitations with 512-byte sector HDD's and for greater storage capacity.

The transition to Advanced Format HDD's will allow storage devices to more easily adopt larger capacities in both laptops and desktops. While hard drives that transition to 4k sectors will maintain backwards compatibility current Advanced Format HDD's, also known as 512e HDD's, will emulate 512-byte SATA and will operate at 4k.

For more information on deploying Dell computers with Advanced Format HDD's including the "5-Steps for Advanced Format Readiness", refer to: Dell TechCenter.

How Does An Advanced Format HDD Impact OS Images?

Even though a 512e drive is designed to be backward compatible, most of current Operating Systems (OSs) are not aware of the Advanced Format technology. Depending on the Operating System and its Service Pack, some extra steps may be required to optimize the performance of the Advanced Format (512e) HDD's and to maintain full Operating System and application functionality. These extra steps could require using alignment tools to fix any sector misalignment as a result of deploying a non-Advanced Format aware image on an Advanced Format HDD which may otherwise cause performance issues. An Operating System is Advanced Format aware if it meets the following criteria:

  • It understands the concept of physical sector vs. logical sector
  • It maximizes writes using multiples of 4k bytes
  • Disk partition starts at the boundary of 4k sector

Not all current Microsoft Operating Systems are Advanced Format aware (Table 1). A system configured with an Advanced Format drive and an Operating System that is not Advanced Format aware can experience sector misalignment, resulting in performance or compatibility issues.

Some extra steps may be required for re-imaging even with Advanced Format aware Microsoft Operating Systems, such as (refer to Table 2 and 3 for details):

  • Install/upgrade to the latest Intel Storage driver
  • Apply the applicable Microsoft KB article
  • Partition alignment
  • Flash to the latest BIOS

Operating System Advanced Format Aware
Microsoft® Windows® 7 SP1 Yes
Microsoft® Windows® 7 Yes
Microsoft® Vista® SP2 Yes
Microsoft® Vista® SP1 Yes
Microsoft® Vista® No
Microsoft® XP - All Service Packs No
Microsoft® Windows® PE 3.0 or Later Yes
Microsoft® Windows® PE older versions No

Timeline for Phase-in of Advanced Format (512e)

Dell does not have a specific cut-over date for the transition to Advanced Format (512e) HDD's.
The transition follows the below guidelines:

  • Since May 2011, Dell has been shipping 2.5" Advanced Format (512e) HDD's. Dell will continue to ship a mix of 2.5" 512b and 512e HDD's until Jan 2014.
  • Dell phased in 3.5" Advanced Format (512e) hard drives around January, 2012. Dell will continue to ship a mix of 3.5" 512b and 512e until Jan 2014, when Dell will stop dispatching 512b HDD parts.
  • These transitions are applicable across all currently shipping Dell Business Client Notebooks, Desktops and Workstations with only two exceptions.
    • OptiPlex XE will remain on 512b native HDD's.
    • Precision T7500 had a delayed transition schedule and began shipping 512e drives in April, 2012.

note the following:

  • While Advanced Format drives are initially being phased in, multi-unit shipments may include both Advanced Format and conventional (512b) drives.
  • Service parts will be replaced like for like.

Partition Alignment Options

Partition alignment is required for older Operating Systems and is recommended for new Operating Systems in order to insure proper HDD performance and imaging between HDD's of differing sector sizes. An aligned partition is when the starting offset of the partition is divisible by 4096 Bytes or by 8 for Logical Block Addressing (LBA) numbers. To verify if the partition is aligned, use the Dell Paragon Alignment Tool Utility as shown in the Detecting Advanced Format (512e) Drives section, or one of the applications below.

Pre-installation partition alignment options of the OS include:

Using Ghost:< >Ghost 11.5 will maintain the alignment state of the Gold/Master image. If the disk image is built and aligned on a 512e/Advanced Format drive, the clones of that image will remain aligned. If the image is built on a 512B, Ghost command line switch {-align=1MB} can be used to ensure alignment when deployed to any drive.DISKPART may be used to enable storage configuration or create a partition at an explicit disk offset from a script, a remote session, or another command prompt. Dell recommends using WinPE's (3.0 or greater) Diskpart.exe from Windows Vista or Windows 7 to create the partitions for Windows XP installation. This will create a partition that is Advanced Format aligned. Without PE, starting with Windows Vista or Windows 7 DVD to create the partition for the Windows XP will create correct partitioning. On how to use DISKPART utility and how to divide the offset value of the selected partition, refer to Microsoft Knowledge Base Article: "A Description of the Diskpart Command-Line Utility" Article ID: 300415.A post-installation option for partition alignment of the OS is the Paragon Alignment Tool (PAT). The free edition of PAT is a hardware agnostic tool available for download from the Dell Support website in Dell Drivers and Downloads for your system under the SATA Drives section. This free edition can be used after an Operating System is installed to align the partitions of an Advanced Format drive, one system at a time.scriptable post-installation option for partition alignment across large deployments or for enterprise customers is available as of November 2011. The Paragon Alignment Tool (PAT) 3.0 Scriptable Staging Edition is a licensed based, hardware agnostic tool available from your Dell sales team. Similar to the free edition, it will perform alignment post OS installation for those customers requiring additional staging functionality. More information on the Scriptable Staging Edition of the PAT tool can be found under Advanced Format: Dell Solutions for Corporate Customers . A post-installation option for validating partition alignment of the Operating System is the Dell Advanced Format Detection Tool. The Dell Advanced Format Detection Tool is a hardware diagnostic tool available for download from the Dell Support website in Dell Drivers and Downloads for your system under the SATA Drives section. This tool can be used after an Operating System is installed to align the partitions of an Advanced Format drive.

What is Dell Doing to Help With Intel Storage Driver and QFE/KB Article Update Which are Required on Some Operating Systems?

Dell factory process will validate the presence of the Mass Storage Driver and QFE/KB article based on the Windows images version (Table 2). Your Dell GCS PM will offer to update missing files as necessary.

Back to Top


Why Will Windows Update Fail and Why are the QFE/KB Articles Required?

Applications that are built on ESENT, such as Windows Update, receive an error message and terminate when the reported physical sector size changes across Operating System sessions. Therefore, if an image is created on a non-4k drive, and cloned to an Advanced Format drive (or vice versa), after recovery, the OS will detect the different physical sector size (4k vs. 512B). The Windows update will hang up. A reboot or re-installation may resolve this issue.

Back to Top


What Happens if I Don’t Install the IRST Driver?

In some instances, this error message appears during the installation: Windows setup could not configure Windows to run on this computer’s hardware.

Back to Top


Why is Partition Alignment Required?

An aligned partition will provide the best performance. As much as possible every partition should start with LBA offset that is aligned to a drive’s physical 4k-sector to reduce the performance impact. Writes to the disk that are not "aligned" will require the HDD to first read the original 4096 bytes, then merge the new write data with the existing 4096 bytes that are not changed, and then write that whole block of 4096 back to the disk. This causes an approximate 20~30% performance degradation, especially for the write performance.

Back to Top


When is Partition Alignment Required?

Partition alignment is recommended when performing operations that can change the alignment state, like reimaging, reinstalling or cloning.

Back to Top


Do I Need to Align my Image on a 512B (Legacy) Drive?

No, 512B (legacy) hard drives do not need to be aligned. However, images originally built on 512B legacy drives may require additional alignment when installed on 512e drive. Dell’s factory process will align existing images while customers build AF compatible images.

Back to Top


What Methods Can be Used to Align the Drive Image?

Options:

  • Ghost switch (during cloning) Ghost command line switch {-align=1MB}
  • Diskpart (pre-install) Use WinPE's (3.0 or greater) Diskpart.exe from Windows Vista or Windows 7 to create the partitions for Windows XP installation. This will create a partition that is Advanced Format aligned. Without PE, starting with Windows Vista or Windows 7 DVD to create the partition for the Windows XP will create correct partitioning. Additional information from Microsoft on using Diskpart can be found in Microsoft Knowledge Base Article: "A Description of the Diskpart Command-Line Utility" Article ID: 300415.Paragon (post-install) Third party utilities can be used to align your drive after Windows is installed.
  • Paragon’s Utility for Dell is available for download from the Dell Support website in Dell Drivers and Downloads for your system under the SATA Drives section.

Back to Top


What Happens if I Run a Partition Alignment Tool (Such as the Paragon Alignment Tool) on a Drive That is Already Aligned?

If a partition alignment tool is run on a drive that is already aligned, the tool will detect the alignment and complete without impacting the drive or image.

Back to Top


What Happens if I Don’t run a Partition Alignment Tool?

Systems with unaligned partitions will likely experience performance degradation and some sector-based imaging tools may experience compatibility issues. It is recommended to follow the imaging steps referenced in the Detecting Advanced Format (512e) Drives section.

Back to Top


Can I use Ghost and Maintain Image Alignment?

Yes, Ghost 11.5 will maintain the alignment state of the Gold/Master image. If the disk image is built and aligned on a 512e/AF drive, the clones of that image will remain aligned. If the image is built on a 512 legacy drive, Ghost command line switch {-align=1MB} can be used to ensure alignment when deployed to any drive.

Back to Top


How Long Does it Take to Align a Drive With the Paragon Alignment Tool (PAT)?

The time it takes to complete alignment is dependent upon the amount of data within selected partitions, the overall performance of the system, and any data loss protection options enabled within the PAT utility. Roughly stated PAT performs at just over a gigabyte per minute, assuming no data loss or file system checking safeguards are in place.

Back to Top


Is the Paragon Tool Scriptable?

Dell offers two editions of the Paragon alignment tool:

  • The free edition, which runs inside the Operating System and is not scriptable and is provided to Dell customers for download from the Dell Support website in Dell Drivers and Downloads for your system under the SATA Drives section.
  • Dell also offers a Scriptable Staging Edition of the PAT tool, which is license based and suitable for those customers requiring additional staging functionality. This edition is available through your Dell Sales team. More information can be found under Advanced Format: Dell Solutions for Corporate Customers.

Back to Top


How do I Validate the Partitions are Aligned After the Operating System has Been Installed?

Options:

  • Use the Dell Advanced Format HDD Detection Tool as found on the Dell Support Website in Drivers and Downloads section, or one of the applications below.
  • Using the Dell Paragon Alignment Tool Utility: The Paragon Alignment tool can be used to validate that the partitions are aligned. Instructions for installing and using the Paragon tool can be downloaded from the Dell Support website in Dell Drivers and Downloads for your system under the SATA Drives section.
  • Using a Script: You can use the commands wmic partition list full or wmic partition get startingoffset,name,index in Command Prompt. Alternatively, type MSINFO32 in Command Prompt, once in System Information, click Component, then Storage and finally Disk, to look for the number of partition Starting Offset; then divide it by 4096. The partition is aligned if you get an integer. More sample scripts (VBScript and Powershell) can be found at the Dell TechCenter.

How is Dell Notifying Customers That a new Computer may Contain an Advanced Format Drive?

A flyer is being inserted into the shipping boxes of new Enterprise Client systems that are capable of having an AF drive (Figure 3). It is important to note that the flyer is not an indicator that the system does contain an AF Drive and no action is required if they have a legacy 512 hard drive or it is not planned to re-install the Operating System on the computer.
Read the flyer carefully as it contains very important information.

The Paragon Alignment Tool (PAT) is reporting 512b legacy drives as having non-optimally aligned partitions. What do I need to do?

 PAT supports partition alignment on 512b native (non-AF) HDDs. When a HDD is reimaged, it is customary to create/recreate partitions on the HDD to receive the image. If the partition's starting offset is a value which is not divisible by 4096, then it is not properly aligned and PAT will offer to align it, if the drive supports alignment. When using a Dell client system with a single non-AF 512b legacy drive the customer can choose whether they wish to align the partitions as there is no performance improvement, nor loss thereof, on these drives whether they are aligned or not. However, when using multiple non-AF 512b legacy HDD’s in a RAID configuration, Dell recommends aligning the partitions due to potential performance degradation

Back to Top


What if the SATA configuration mode is set to "ATA mode" in the BIOS with an AF drive?

Intel RST storage driver cannot be used in "ATA mode" SATA Configuration mode, Intel RST driver can be loaded only in RAID and AHCI SATA Configuration modes. Dell recommends using the configuration inclusive of the Intel RST storage driver version 9.6 or greater.
