I'm seeing a boatload of the same error:

So I presume a bad block/sector on the disk.
I had high hopes this article:
https://www.freebsddiary.org/smart-fixing-bad-sector.php
would show the way, but it seems to quit right at the good stuff.
Can it be remapped, and if so, pointers to how?
Thanks,
Gary
