provides instructions for preparing an Advanced Format hard drive for a Microsoft® Windows® installation on an HP Business Notebook or Desktop PC, , making the drive easier to manufacture and able to support higher capacities. First-generation Advanced Format drives retain backwards-compatibility - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 3
Windows 7 Windows Preinstallation Environment (WinPE) 3.0 or later Tables 1 and 2 outline a number of scenarios involving the use of Advanced Format-aware drives and recommends actions you should take to optimize the performance of your HP Business Notebook or Desktop PC, or Retail POS system. 3 - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 4
system performance, with links to the appropriate downloads Scenario Actions A Your Advanced Format drive is aligned. To optimize performance with Windows 7 or WinPE, apply Microsoft Knowledge Base article 982018.

Tool to ensure partitions are aligned. Note: If you are downgrading your PC to Windows XP or Windows Vista, you are impacted since these OSs are on this drive. If your drive is misaligned, before proceeding, you should decrypt, align and re-encrypt the drive using the instructions provided with - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 6
furthermore, depending on the amount of patching employed in the image, other problems may occur. Thus, if you are using ImageX, rely on Diskpart to your smallest target drive. When applying the image, do not allow the disk imaging utility to extend the partition on the target drive. Change the - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 7
would take significantly longer than applying the same image to a traditional hard drive. To optimize performance, you should apply the appropriate hotfix to your HP Business Notebook or Desktop PC, or Retail POS system, as described in the following procedure. Procedure Performance degradation - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 8

Using DiskExt 1. After the operating system has been installed, download the DISKEXT utility from http://technet.microsoft.com/en-us/sysinternals/bb896648; install. 2. Run diskext from the Windows command line. 3. Identify the Partition Starting Offset - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 10
Sample validation The example shown in Table 3 shows the sizes and offsets associated with four partitions. All eight values must be divisible by 4,096. Table 3.

cut-over date for the introduction of Advanced Format drives into new HP Business Notebook or Desktop PCs, or Retail POS systems; instead, drives will be phased in, as shown in Table 4. Note the following caveats: While Advanced Format drives are initially being phased in, multi-unit shipments may - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 12

What happens if I am running an older operating system with conventional drives or a mixture of conventional - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 13
, a BIOS update would be required for every system. Moreover, some operating systems do not support booting to 4-KB native drives. Older applications advantage for a customer. Thus, HP elected to not pursue this approach at this time. Where can I build an Advanced Format drive-aware image? As long as - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 14
models: Notes 1. WinPE: Microsoft Windows Preinstallation Environment 2. For more information on creating the image (including driver requirements), refer to this white paper. You can create the image on a drive with 512 byte or 4 KB sectors. 3. Use the Windows Automated Installation Kit (AIK). 14 - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 15
size constrains storage capacity and has also caused manufacturing capabilities to reach a limit. Under the sponsorship and support of the International Disk Drive Equipment and Materials Association (IDEMA), manufacturers of industry-standard HDDs are transitioning from 512-byte to 4KB sectors - HP Envy 15-1102xx | Preparing Advanced Format hard drives for Microsoft Windows - Page 16
, if logical writes are aligned to physical sectors and write lengths are in multiples of 4 KB, then new data can completely replace old data; the drive does not have to perform any extra steps for a write operation.
