Restore may have layed out your files differently, and in particular may have overwritten the "bad spots" on your disk. Note that newer disks are "magical" with their block recovery, in that they only ever give read errors. If you try to write to a bad block, it will be automatically remapped, so overwriting the bad sectors with data will have fixed the bad sectors and "badblocks" will likely not show any problems.
