i am trying to query the physical sector size of my drive using fsutil:

C:\Windows\system32>fsutil fsinfo ntfsinfo c:
NTFS Volume Serial Number :       0x78cc11b2cc116c1e
Version :                         3.1
Number Sectors :                  0x000000003a382fff
Total Clusters :                  0x00000000074705ff
Free Clusters  :                  0x00000000022fc29b
Total Reserved :                  0x00000000000007d0
Bytes Per Sector  :               512
Bytes Per Physical Sector :       <Not Supported>
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024
Clusters Per FileRecord Segment : 0
Mft Valid Data Length :           0x00000000305c0000
Mft Start Lcn  :                  0x00000000000c0000
Mft2 Start Lcn :                  0x0000000003a382ff
Mft Zone Start :                  0x0000000006951940
Mft Zone End   :                  0x0000000006951c80
RM Identifier:        19B22CBE-570D-19DE-9C72-CD758F800DDC

You can see that the Bytes Per Physical Sector value is Not Supported:

Bytes Per Physical Sector :       <Not Supported>

In KB Article Microsoft support policy for 4K sector hard drives in Windows, Microsoft says:

• If fsutil.exe continues to display "Bytes Per Physical Sector : " after you apply the latest storage driver and the required hotfixes, make sure that the following registry path exists:

  HKLM\CurrentControlSet\Services\<miniport’s service name>\Parameters\Device\
        Name: EnableQueryAccessAlignment
        Type: REG_DWORD
        Value: 1: Enable
  

The only thing i don't know is what my Miniport's service name is.

What is my miniport's service name.

i know that my SATA drives are in AHCI mode, and AHCI uses the msahci driver service:

Is that my miniport service? "MSAHCI"?
