Did you install a partition table on the disk (or otherwise opened it =
for writing) after you swapped it in?

I can't think of many reasons why you would get an I/O error if the =
controller is happy with the disk (as the later messages indicate), so =
I'm speculating that the provider feels it's device has gone; opening =
mfid3 for writing might trigger a proper GEOM retaste (dd if=3D/dev/null =
of=3D/dev/mfid3).
