  We had some similar errors on a RA81 on a VAX 750 running 4.3 BSD:

  Dec 20 17:14:32 bucsb vmunix: uda0: soft error, disk transfer error, 
  unit 2, grp 0x0, hdr 0xd4c27, event 0650
  Dec 20 17:14:32 bucsb vmunix: uda0: soft error, disk transfer error, 
  unit 2, grp 0x0, hdr 0xd4ef1, event 0650
 
  I did a level 0 dump of the entire disk.  DEC ran 'EVRLB' from the
  diag supervisor and then I restored the disk.  So far, no errors.

  Was this the "correct" thing to do?  DEC said the drive was ok as far
  as they could tell, but they would replace the HDA if I got errors 
  after doing the format.

  I would be interested in hearing about tools I could use to map out
  bad blocks or sectors (I have done this without too much trouble on
  the Sun, Encore and Celerity products).
