The only way you could do that would be to format the drive on a machine that 
handles > 128Gb drives then put it in a machine that doesn't.  If you format it 
on a machine without LBA48 support it CANNOT be written past 128Gb.  Without 
either built-in LBA48 support or a patch the OS can't write a file past the 
limit, because it's the limit.
