There is now a <code>sectorInfo</code> sub-command which may provide better information:

i wanted to expand on Chris Gessler's answer, and note that there is no known way to get the Physical sector of a drive using Windows Management Instrumentation (WMI), e.g. <code>wmic</code>.
Given that i have an Advanced Format drive (i.e. it uses 4,096 bytes per sector rather than 512):
<pre><code>C:\Windows\system32&gt;fsutil fsinfo ntfsinfo d:

Free Clusters : 0x000000000e7b2813
Total Reserved : 0x0000000000000000
Bytes Per Sector : 512
Bytes Per Physical Sector : 4096
</code></pre>
<strike>Neither WMI's <code>DiskDrive</code>:
<pre><code>wmic:root\cli&gt;diskdrive
Availability BytesPerSector Capabilities CapabilityDescriptions Caption
 512 {3, 4, 10} {&quot;Random Access&quot;, &quot;Supports Writing&quot;, &quot;SMART Notification&quot;} ST1000DM003-9YN162 ATA Device
</code></pre>
</strike>
 
nor <code>Partition</code>:
<pre><code>wmic:root\cli&gt;partition get BlockSize, StartingOffset, Name, Index
BlockSize Index Name StartingOffset
512 0 Disk #0, Partition #0 1048576
</code></pre>
can report the underlying physical sector size. It makes sense when you realize they both report the sector size that Windows is using. It is 512 bytes per sector - the drive just happens to be different inside.
That's because only Windows 8 supports use of 4k sectors. Windows 7 understands that the drive might be 4k, and works to align it's 4k Clusters with the hard-drive's underlying 4k Sectors.
<h2>Update</h2>
<code>wmic diskdrive</code> now does show physical bytes per sector in <code>Bytes per Sector</code>:
<pre><code>C:\Windows\system32&gt;wmic
wmic:root\cli&gt;diskdrive
Availability BytesPerSector Capabilities CapabilityDescriptions 
 4096 {3, 4} {&quot;Random Access&quot;, &quot;Supports Writing&quot;} 
</code></pre>
While <code>wmic partition</code> continues to be wrong.

entityMap|blocks|key|9b50o|text|如果你真的想以编程的方式使用它，你需要发送IOCTL_STORAGE_QUERY_PROPERTY，提供PropertyId设置为StorageAccessAlignmentProperty的STORAGE_PROPERTY_QUERY。这给出了物理和逻辑扇区大小。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|9r1ga|注意:这只适用于Windows+Vista和更高版本。^0|L|S|1G|A|1T|U|2O|M|0^^$0|$]|1|@$2|3|4|5|6|7|8|I|9|@$A|J|B|K|C|D]|$A|L|B|M|C|D]|$A|N|B|O|C|D]|$A|P|B|Q|C|D]]|E|@]|F|$]]|$2|G|4|H|6|7|8|R|9|@]|E|@]|F|$]]]]

If you really want to have it programmatically, you need to send <code>IOCTL_STORAGE_QUERY_PROPERTY</code> providing <code>STORAGE_PROPERTY_QUERY</code> with <code>PropertyId</code> set to <code>StorageAccessAlignmentProperty</code>. This gives both physical and logical sector sizes.

Note: this only works on Windows Vista and higher.

How can I determine the Physical Sector Size (e.g. if i have an <a href="http://en.wikipedia.org/wiki/Advanced_Format">Advanced Format</a> drive with 4,096 byte sectors rather than the legacy 512 byte sectors) in Windows 7?

I know that by clicking on a file and get properties we can find out the NTFS Cluster Size, but that's not the same as the hard-drive's sector size.

Note: We ask about Windows 7 because it (and Windows Vista SP1) understand the existence of 4096 Advanced Format hard drives.

 如何确定Windows 7中的物理扇区大小(例如，如果我的高级格式化驱动器具有4,096字节扇区，而不是传统的512字节扇区)？ 我知道，通过单击文件并获取属性，我们可以找到NTFS集群大小，但这与硬盘驱动器的扇区大小不同。 注意:我们询问Windows7是因为它(和Windows Vista SP1)了解4096高级格式化硬盘的存在。
