These things are supposed to sort themselves out via SMART aren't they. I've had input/output error from dd before and mhdds makebad which simply adds the sector to the SMART bad sector list has made that sector invisible. I'm sure there's plenty of unix apps that can do the same, though I don't remember having luck with them. Are you saying if I had written with dd rather than read with dd, SMART would have marked it as bad?
