Which wd drives have advanced format

That is the reason I am complaining about it. So, in addition to the label on the drives, the specification for each drive model on your website should mention if that model is AF or not.

So, the WD Align tool should notice the unaligned partitions and give me the option to align them. It says the partitions are aligned even though they are not. Problem is that I cannot tell if a hard drive sealed in an anti-static pouch is an AF drive or not. One way I can think of doing it is to open the pouch, connect the drive to a system, and run the Disk Alignment Test program.

So, if anyone can tell me which of the drives listed in my OP are non-AF drives, it would be helpful. The advanced format technology defines the basic size of all disk sectors.

And it also known as 4K Advanced Format. Advanced Format can help to greatly increase the storage space. It adopts the latest firmware to perfectly serve the operating system and other facilities. For a long time, the hard disk uses byte sectors to read and store data.

With the capacity of hard drive continues to increase, the hard drive manufactures decide to increase the sector capacity up to 4KB to meet demand. This technology utilizes the surface of storage media more effectively by combining data that would have been stored in eight byte sectors into one single sector that is bytes in length.
