For a drive formatted with ReFS, with a mirror, will it self heal if there is a bad sector?

Under Windows 8.1, if I format a drive to ReFS, then add a mirror using Disc Management, will it self heal if there is a bad sector on one of the drives? Or do I have to use Storage Spaces to take advantage of the self healing capabilities of ReFS?
