Introduction

This article describes a hotfix that adds the FileFsSectorSizeInformation information class to Windows 7 and to Windows Server 2008 R2.

Note The FileFsSectorSizeInformation information class is used to return a FILE_FS_SECTOR_SIZE_INFORMATION structure that contains information about the physical and logical sector sizes of a volume.

Before you install this hotfix, you can enable physical sector size reporting by using the IOCTL_STORAGE_QUERY_PROPERTY control code. However, this control code has the following limitations:

  • The control code can only be called on a volume handle. Elevated permissions are required to perform this operation.

  • The control code cannot be sent by using the Server Message Block (SMB) protocol, and applications that use the control code do not support the SMB protocol.

The FileFsSectorSizeInformation information class that is added when you install this hotfix provides the following advantages:

  • The information class can be called on any valid file handle. Elevated permissions are not required to perform this operation.

  • The information class can be used in an SMB environment, and applications that use the information class support the SMB protocol. For example, the information class can be used to return the physical sector size of a remote file share.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
