I've had the same problem and discovered that fdisk will only make a max 
partition size of around 130GB. The only way around it I've found is to 
format the disk during a graphical install. I've heard rumors that a 
'fixed' fdisk exists but don't know. Also some other partitioning tool 
may do what you want.
