If a read gives a correctable ECC error it will never tell you, otherwise you will get a read error on the sector. Writing to that sector will then force a spare sector to be used in the future. >Mainly, I am wondering whether the drives can automatically deal with new >bad sectors as they appear. yes, as per the above. If you disk starts making "klONK" sounds, it's trying to tell you that it feels sick and that you should make a backup asap and replace it. You may want to try to get it replaced under warrenty. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
