You're thinking CD. Think Vinyl instead.
Most HD manufacturers do block 0 on the outer side, then travel to thje
last block, that is on the innermost cylinder (physical cylinder, not
that DOS crap). I only know of one current drive that does it slightly
different: An IBM notebook 2.5" HD goes from outside (fast) to inside
(slow) with about 2/3 of it's capacity, then goes to the outside (fast)
again.
