You've got some misconceptions. Those drives do sector remapping. Using

# smartctl -a /dev/hdx
# hdparm -I /dev/hdx
may help.

Okay, that makes sense. But I need to write something to them to have
the FEC detect a failure and remap it?
You do that all the time when you use the disc. A new disc from
the manufacturer has already been through more stringent tests
than you can do at home. I look at that data about 2 or 3x per
year, and I haven't seen any errors on my disc yet.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
