sector I/O error cause disk to be "faulty" in raid5

Hi, everybody:
In current raid5 implementation, if a r/w error occured at some
specific sectors on a disk, the disk will be labeled as "faulty".
Here, I want to say in most cases, this is failure indication of those
sectors not the whole disk. Should we make some changes to be more
reasonable?

It's already on the wishlist as a bad block map.

Cheers,
