The need for initialising disks before use?

A quick question - is it recommended to initialise disks before using
them to allow the disks to map out any "bad spots" early on? I've seen
some "uninitialised" disks (ie. new disks, thrown into a machine,
newfs'd) start to show read errors within a few months of deployment,
which I thought one or two might seem okay, but on a number of machines
is more than a coincidence...
Is it recommended/required to do something like:
dd if=/dev/zero of=/dev/ad0 bs=1m
before use to ensure the drive's sector remappings are all in place,
before then doing a newfs?
FWIW, I've been seeing this on more 6.0 systems that I would have
thought to be just chance...
