FYI:
Around 1992 or 1993, I rewrote Minix-fsck to do this instead of
seeking all over the place.
Cut the total time to fsck my filesystem from around 30 to 28
seconds. (remember the days of small filesystems?)
That's when I decided that this was NOT an interesting project: there
was very little to be gained.
The explanation is: A seek over a few tracks isn't much slower than a
seek over hundreds of tracks. Almost any "skip" in linear access
incurs the average 6ms rotational latency anyway.
