Proper alignment will be dependent on the deployment methodology and tools that you use. Now with the physical sector being 4K and the emulated logical sector still being 512 bytes, you encounter performance issues if the start of the logical partitions donâ€™t line up with the boundaries of the physical sectors. With previous (512B) drives the physical and logical sector size was always 512 bytes. The post on the Dell community blog lists one of the issues that users can run into when working with AF hard drives. (I suggest you check the Exploring WD's Advanced Format HD Technology over at Hot Hardware and Dell's Are you ready for Advanced Format (AF) Hard Drives for additional information).

Some hard disk manufacturers like Western Digital are offering software tools for operating systems like Windows XP to make their AF hard drives compatible with the operating system as well. I ran a CHKDSK /F /offlinescanandfix - no bad sectors were found. I backed up all the files and erased the drive. Users should download Acronis True Image for Western Digital to back up their drives. When it comes to Windows, only the latest versions of Windows Vista and Windows 7 support it natively. My Passport 0740 WD Drive Utilities Quick Drive Test failed, but Windows 10 CHKDSK finds no errors. Install WD Discovery for Windows WD Backup (Support for WD Backup has ended. Not all operating systems support AF hard drives. The core benefit of the new technology is that data can be stored more efficiently. The Advanced Format drives emulate that sector for compatibility reasons. The main difference is that AF drives use a 4K physical sector instead of a 512 byte logical sector that conventional hard drives use.

This however is changing currently with the introduction of the first Advanced Format hard drives that some PC manufacturers have started to add to their systems. There is not really a lot that users can do to improve the performance of a hard drive on a computer system.
