well, actually... the ATA bus on this iMac will not recognize any space on a disk 
beyond 128GB. doesn't matter how you partition it. this is part is a hardware 
limitation. "partitioning" is mostly for human consumption, though there are some 
exceptions (such as the 8GB OS X boot restriction on this model). an ATA bus isn't 
sophisticated enough to address disk space beyond somewhere in the vicinity of 128GB.

basically... the method ATA/66 uses to count disk space is only capable of counting up 
to ~128 billion bytes. the hardware just can't go any higher. later revisions of the 
ATA architecture upped the ante, allowing the computer to address more disk space.
