I understood that, but on pre-OSR2 machines, DISKSPACE() should return the same value as GetDiskFreeSpace(). I believe that the reason that both DISKSPACE() and SYS(2020) report erroneous results on larger drives is that they call GetDiskFreeSpace(). Or am I missing something.

Kind of, but I think it was named that way for backward compatibility with Win16, but I'm not 100% certain of that.
