     I ran 2.3 for quite a while and would get the HD errors anytime I
  had heavy activity on both drives. It was for this reason that I
  resisted putting my /usr/spool directory on the second drive. One
  sure way to reproduce the bug was to do cpio's > /dev/null on both
  drives simultaneously.

     Upon installing 2.4U I exercised the drives quite heavily to get
  a feel for wether the drive bug was fixed or not. I ran everything I
  could think of including several simultaneous cpio's. I could not
  reproduce the drive bug and was confident it was fixed. I'm using 
  two 28ms access drives (1-Miniscribe, 1-CDC). The errors you describe
  above are not common.
