Other than to tell you Linux is simply reporting back what the drive itself reported - which is a physical failure to recover a sector of data no. A test that rewrites such a sector will generally clear the error, its one of the problems of some diagnostic tools. A pure read test should fine the error again unless its something like overheat causing the problem. SMART data will tell you drive temperatures
