How to check 4k alignment?

[uflex]

My SSD is 4k aligned.

 

 $Data = _WinAPI_GetDriveGeometryEx($Drive)

 

 

ConsoleWrite('Bytes per Sector: ' & $Data[4] & @CR)   

 

will return 512.

 

Does anynone know how to check 4k ?

 

Thanks!

What does "4k alignment" even mean?

It will help your cause if you explain this whole thing.

I understand, but I will await the OP to explain further.

But I will give a clue >> http://msdn.microsoft.com/en-us/library/windows/desktop/ff800831(v=vs.85).aspx

Thanks.

The solution uses  WMI. It will do.

In fact , I want to work in PE(the solution in the article  also use WMI).

Is there other way not to use WMI?

Just hope so.

It seems that it is the  point.

I will study the material.

Have a look at WinAPIEx as well, especially DeviceIoControl.
