You can try 'camcontrol reassign'. joerg sent me patches last Fall to implement it, and I've been planning on turning it into a scan and reassign tool. (i.e. scan the disk, look for read errors, and attempt to reassign the block) Anyway, the patches are here: http://people.FreeBSD.org/~ken/camcontrol.reassign.20030428 Let me know how things work.
