users and consumers, this white paper provides instructions for preparing an Advanced Format hard drive for a Microsoft® Windows® installation on an HP Business Notebook or Desktop PC, or Retail Point-of-Sale (POS) system. Historically, hard disk drives (HDDs) have used 512-byte sectors; however - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - 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 G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - Page 4

. When applying the image, do not allow the disk imaging utility to extend the partition on the target drive. Change the value of the EOP key to the desired value. When the duplicated disk is turned on, Windows Setup extends the partition to the size specified in the sysprep.inf file. 3 For more - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - 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 can - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - Page 8

PE 3.0 RAM media. 2. Execute the Diskpart utility to display information about specific system partitions. For example, use the following script is to display information about Disk 0, Partition 1 (as shown in Figure 2): diskpart select disk 0 select partition 1 detail partition Figure 2: Sample - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - Page 10
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.

There is no set 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.

512-byte sector - notably the hard disk boot device. The resources needed to update the environment would have been vast; for example, a BIOS update would be required for every system. Moreover, some operating systems do not support booting to 4-KB native drives.

Hard drive deployment decision tree for managed IT The following decision tree for managed IT applies to 2011 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 - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - Page 15
with current computers. Thus, these drives - sometimes referred to as 512e drives or translated drives - operate internally at 4 KB and externally at 512 bytes. However, this disparity in sector sizes can lead to performance issues. Partition alignment Modern operating systems use file systems with - HP G5050XX | Preparing Advanced Format hard drives for Microsoft Windows install - Page 16
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. Newer operating systems like Windows Vista SP1 or later and Windows 7 start the partition on logical block address 2048, which is divisible by eight.
