szDeviceName (520 bytes): A 520-byte long fixed-length field. It contains a null-terminated Unicode string that contains the drive letter of the volume if the volume has a drive letter. If the volume is not configured with a drive letter, a null-terminated Unicode string of the format "DiskNNNPartitionYYY", where NNN is the disk number and YYY is the partition number, as specified in [MS-DMRP].
szVolumeLabel (520 bytes): A 520-byte long fixed-length field. It contains the file system label. This field is a null-terminated Unicode string.
dwSerialNumber (4 bytes): An unsigned 32-bit integer. This is the serial number that is assigned by the operating system when the partition was formatted.
rgdwMaximumComponentLength (4 bytes): An unsigned 32-bit integer. A value specifying the maximum length, in characters, of a file name component that is supported by the specified file system. A file name component is the portion of a file name between "\" characters.
dwFileSystemFlags (4 bytes): An unsigned 32-bit integer that identifies the file system flags.
