 * DriveNumber (USHORT) - input : Logical drive number, for example, 0 = default and 1 = A, and the FSD for the media currently in that drive. A value of '0xFFFF' notes that FSInfoBuf contains the ASCIIZ path name of the FSD.
 * FSInfoLevel (USHORT) - input : Level of file information to be set. A value of 2 is the only valid value for FSInfoLevel.
 * FSInfoBuf (PBYTE) - input : Address of the storage area where the system gets the new file system information.
 * 1 Length of Volume Label (null not included)
 * 2-N Volume Label ASCIIZ string.


 * FSInfoBufSize (USHORT) - input : Length of FSInfoBuf.
