Just guessing here, without looking at the source code :) but I'd venture to 
suggest that fdisk uses the bios to talk to the disc. Thus, it can read the 
partition data if it's already been written by a sensible program (as that's 
early in the disk) and it *could* write oversized partitions, if it wanted 
to, but it probably checks against the size of bios reported disc size.
