The drive will only remap bad blocks when you try to write to them, so if you haven't written to them then it is no surprise that they aren't going anywhere. If the drive is actually returning bad data rather than failing the read outright, then the only thing you can do is to have btrfs duplicate all data so if the checksum on one copy is bad it can try the other. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJUbN8VAAoJEI5FoCIzSKrwGjkIAKxXbBcMaItyBe08yC/bipUH 2crWLj5MKej1sn1HEo1WqgJM1hCEZuHCBa8I6ZIECcZmzs4rvKhzU4WWIQ7J/tMN 8OYUzdsWboxbKHY5hrNEVsi8QcUTbz7HT3doaaYDhI7qERu1Ib/4FH+m5yFYEIu8 tx5+N2PzyXctDlNnjY/pcFg+I2+QyA5Rb9X+fLpvVoZCEW7TTMhejfKSQpMEfzHW JsYyKwDpQO6cGIWi19P7pgHc2bsCzShPtFo9UQJh5TtuxjsqP01ju1UfQBX0+Y25 B2LDAjyGE71pY68tBuS7EC9XSB9Iks5yEJotmwYTv3/L7bgDeAGPrj5cFOKG9Tc= =8JoK -----END PGP SIGNATURE-----
