DeviceIoReply (16 bytes): A DR_DEVICE_IOCOMPLETION (section 2.2.1.5) header. The CompletionId field of the DR_DEVICE_IOCOMPLETION header MUST match a Device I/O Request (section 2.2.1.4) that has the MajorFunction field set to IRP_MJ_QUERY_INFORMATION.
Length (4 bytes): A 32-bit unsigned integer that specifies the number of bytes in the Buffer field.
Buffer (variable): A variable-length array of bytes, in which the number of bytes is specified in the Length field. The content of this field is based on the value of the FsInformationClass field in the Server Drive Query Information Request message, which determines the different structures that MUST be contained in the Buffer field. For a complete list of these structures, refer to [MS-FSCC] section 2.4. The "File information class" table defines all the possible values for the FsInformationClass field.
