You mean

DECLARE SHORT GetVolumeInformation IN Win32API;
  STRING @lpRootPathName, STRING @lpVolumeNameBuffer,;
  INTEGER nVolumeNameSize, INTEGER @lpVolumeSerialNumber,;
  INTEGER @lpMaximumComponentLength, INTEGER @lpFileSystemFlags,;
  STRING @lpFileSystemNameBuffer, INTEGER nFileSystemNameSize
lproot = "F:\"
lpvol = SPACE(260)
lnnamesize = 260
lnserialno = 0
lnmaxcomp = 0
lnflags = 0
lpsysname = SPACE(260)
lnnamesize = 260
? GetVolumeInformation(@lproot, @lpvol, lnnamesize, @lnserialno,;
  @lnmaxcomp, @lnflags, @lpsysname, lnnamesize)
? lnserialno

If the function returns non-zero, it succeeded. Note that this only works on Win2K and above under Win2K or above servers.
