If a block hdparm has that feature to mark sectors as bad (--make-bad-sector). not sure how that behaves on a re-write by md. I never tried it myself. Maybe you could also do something with device mapper. It does have an error target, and then there's the overlay. I wish dmsetup had some profiles/shortcuts/reciped to make creation of such device mapper tidbits easier or another common tool for those device mapper tricks...
