This blows because I am porting a legacy application from an MVS system. This application accesses two sequential datasets - flat files that are over 10GBs. Since both files have to be accessed at the same time, I was hoping to put them on different platters to avoid disk contention - two processes attempting to read from the same or near cyclinder groups but since like you say all heads are linked together, this wont do much good.
