请教下有关获取硬盘序列号函数的问题PB

yangkai

string ls_volumenamebuffer
string ls_rootpathname
ulong ll_volumeserialnumber
ulong ll_maximumcomponentlength
ulong ll_filesystemflags
string ls_filesystemnamebuffer
string ls_id

ls_rootpathname = "c:"
ls_volumenamebuffer = space(20)
ls_filesystemnamebuffer = space(20)
if not getvolumeinformationa(ls_rootpathname,ls_volumenamebuffer,20,ll_volumeserialnumber,ll_maximumcomponentlength,ll_filesystemflags,ls_filesystemnamebuffer,20) then
  ls_rootpathname = "d:"
  if not getvolumeinformationa(ls_rootpathname,ls_volumenamebuffer,20,ll_volumeserialnumber,ll_maximumcomponentlength,ll_filesystemflags,ls_filesystemnamebuffer,20) then
   setnull(ll_volumeserialnumber)
  end if
end if
ls_id = trim(string(ll_volumeserialnumber))


使用过程中发现此方法对于有些硬盘号无法提取，请问下是什么原因，怎么解决？
