Hi,
  Well I flipped AWRE etc on - Previously where dd'ing reading the disc
would give log messages followed by an I/O error in the DD, now it managed
to kill the machine and cause it to reboot itself. Great.

  The drive surface checked on a Sun; so I scsiformat'd it back on the PC
and it seems OK.

  However:

   1) Can someone explain to me what the Sun is doing with defect lists? How
      do I look at the 'manufacturers defect list' on FreeBSD - and what does
      it affect?

   2) The disklabel stuff STILL doesn't work.  I tried zero'ing the disc
      first; but running disklabel gives me various IOCTL errors.
      I tried using the /stand/sysinstall program and it happily fdisk'd
      but then segfaulted when it tried to label it.  In the end I dd'd
      the partition and disklabel information from another (different sized
      disc) and then edited it - once a sensible partition/disklabel is on its
      happy.

      I think it must be a kernel related thing because the version on the
      boot disc works OK.

Dave
