Justin,

I have been experiencing strange behavior with dump on my -current system.
This is the same system I have been talking to you about with the SCB
pageing code.  I am still running the (11/15) level of -current

[unix Thu 3:19am]:/home/kmitch# dump 0df 61000 /dev/null /
  DUMP: Date of this level 0 dump: Thu Nov 21 03:20:12 1996
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rsd0a (/) to /dev/null
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 34496 tape blocks on 0.05 tape(s).
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
  DUMP: read error from /dev/rsd0a: Input/output error: [block 9376]: count=8192
  DUMP: DUMP: 34501 tape blocks on 1 volumes(s)
  DUMP: finished in 45 seconds, throughput 766 KBytes/sec
  DUMP: Closing /dev/null
  DUMP: DUMP IS DONE


I don't think this is the drive.  I have re-lowlevel'd the drive and
reconstructed the file system and still get these errors.  During the
process, I booted from a 2.1.5 disk and I could run dump without any
problems at all.  I also ran Adaptec's verify utility to make sure there
were no media defects and it couldn't find any.


Any Idea what may have caused this??
