    Write error on disk block but format read is OK

    853255
      PLATFORM DESCRIPTION
      T3-2
      Solaris 10u9

      PROBLEM DESCRIPTION
      Two disk write errors on disk blocks. The format/read throws no defect on the surface. I would like to know how to determine if the write error was due to a disk defect or to another source. Morover, I would like to know how to early detect future write errors on disk.

      Following error is showed in /var/adm/messages:

      ACTIONS TAKEN
      I applyied format/read of the whole disk ( 2 passes ) but no defects were found.
