Remapping is only possible when writing to blocks. The disk can not remap on reads. By forcing writes to such blocks you can remap them but the data on them is still lost. I use some partitions with almost only read access that had bad blocks and I could fix the problem with dd if=/dev/zero of=/dev/rsd0x (not important data so I did not replace the disk) -- :wq Claudio
