I have used the Battmem program to set the "Seagate bit" to 2 secs, but
this did not change the symptoms whatsoever. (other than add 4 secs to my
startup!)  I also changed the SCSI to synchronous.  I did this because I 
was told that both of my HDs support this.  Was this the right thing to 
do?  It did seem to speed up my drives though! 
  I did find that changing the SCSI id# for the drives did make difference.
I still have not completely solved the problem yet, but I am able to cold-
boot the 3000 and have the 2nd HD recognized now.  The problem, every
other warm-reboot not recognizing the 2nd HD, still exists though.
