Two reasons, really. The first is for performance.
The second reason is more superstitious than anything else. I
figure that defects come from three possible sources: uneven
media, scratches during manufacture, or unwanted head landings.
Since I can't be sure what the cause was, I assume it was the
worst case - the head landing. If it landed on one sector of a track,
it likely did some damage to other sectors. I don't trust them.
