re above, I was recently advised by a tutor on a Sequent SVM course (so pretty trustworthy I think) that a technique now in use called 'zoning' makes it almost impossible to do the above. With zoning, there are more sectors in the outside area of the disk, than the inside, so unless you know the zoning algorithms, you cant actually tell where the middle of the disk is. I think that hpc3010s have zoning, and presumably others too ?
