He should be able to get the sector numbers by running long self tests. On the disks I have own, this only gets you one sector per scan rewrite cycle. Also note that linux tools such as dd write 8 sectors at a time and if you try to write less than that, a read will be tried first which will most likely fail because of the bad sector.
