OK... I didn't see that function; It's like an extended version of 
GetFileAttributes. I see it also has dwVolumeSerialNumber. Is that used 
to verify unique filesystems? I think it would be good for all boxbackup 
  platforms to include some sort of disk/filesystem ID or label to 
verify that the right filesystem is there.
