They should try to rewrite and write verify the block before remapping it, as there is only a finite amount of spares. For SCSI drives, there's also J�rg Schilling's "sformat" tool that can do the "badblocks" stuff directly in the drive rather than through all the kernel buffers, and can also refresh or reassign bad blocks. -- Matthias Andree
