  Thanks to Rich Copeland, Pat O'Brien, Alan Rollow, Dr. Thomas Blinn, Mike
Broderick and Roberto Romani for responding.

  Probably the best way to do this is to use /usr/field/diskx, but system
exercisers are not installed and I have no way to install them on this
machine.

  SCU also works. I did a low-level format on the disk and it didn't blow
any errors. There are some media scanning features with scu as well, but
finding the right command format for scu gives me migraines, so I gave up on
that.

  Another interesting idea is to use dd. I'll copy that post:


        1. dd if=name-of-raw-c-partition of=/dev/null bs=something-large

                dd if=/dev/rrz0c of=/dev/null bs=1024k

                dd if=/dev/rdsk/dsk0c of=/dev/null bs=1024k
  

   I believe now that the disk media itself is OK, but it is possible that
the filesystem was damaged...and since I used scu to format the disk, now
we'll never know. ;)

        Can anyone tell me how to check a disk media surface from the OS
level? I'm trying to get a troublesome disk replaced, but all I can find
through dia and uerf are some old soft errors.

thanks
