Q. How can I check how many bytes per sector my NTFS volume uses?

A. Using the fsutil command, you can query an NTFS volume to check how many bytes per sector a volume uses. Specify the "fsinfo ntfsinfo :" parameters, as shown here:

C:Usersjohn>fsutil fsinfo ntfsinfo d:
NTFS Volume Serial Number : 0xbca2e805a2e7c1ce
Version : 3.1
Number Sectors : 0x000000015d4befff
Total Clusters : 0x000000002ba97dff
Free Clusters : 0x000000001278e3f7
Total Reserved : 0x0000000000014b30
Bytes Per Sector : 512
Bytes Per Cluster : 4096
Bytes Per FileRecord Segment : 1024
Clusters Per FileRecord Segment : 0

Note that Bytes Per Sector is 512 in this example.
