What does the Advanced Format drive mean to you? 
This section outlines a range of scenarios involving the use of Advanced Format drives and describes 
actions that should be taken to optimize performance in each case. These actions typically depend on 
the OS being used. 
Partition alignment 
When running an OS that is not Advanced Format-aware in conjunction with an Advanced Format 
drive, your system may experience performance issues due to misalignment between logical sectors 
(OS) and physical sectors (disk media) – also referred to as a misaligned partition. 
Microsoft Windows 7 and Windows Vista SP1 or later are Advanced Format-aware; thus, no 
realignment is required. 
Note 
This white paper does not provide guidelines for Windows 8 systems.  
When creating or deploying an image for an OS that is not Advanced Format-aware, you can 
typically use tools like Microsoft DiskPart or Symantec Ghost. For an image that has not been aligned 
during creation or deployment, use one of the following processes: 
  Use an interactive remedial tool such as the Paragon Partition Alignment Tool 
  Use a scriptable solution such as Microsoft ImageX or Ghost: 
ImageX 
1.  Create a backup image using ImageX. 
2.  Use DiskPart to create an aligned partition. 
3.  Use ImageX to restore the image. 
Ghost 
1.  Create a backup. 
2.  Restore the backup while using the –align=1MB switch.
