Here's another of my weekly (or so it seems) problem postings, this time
concerned with a problem I was having with my SCSI card and hard drive.  

I turn on the GS like usual (SCSI card in slot 7, one Quantum daisy chained off
one Syquest, termination only on the Quantum).  Instead of the thermometer
display, I'm greeted with the red light on my hard drive flashing at a regular
interval, and system fails to boot.  Suspecting a hard drive crash, I remove
the Quantum from the chain, and attempt to boot with the Syquest, with no luck. 

Since this problem has occurred off and on over the last two weeks (but always
fixable by turning everything off and back on), I suspect bad connections on
the SCSI card, and clean the fingers on the (Rev. C) SCSI card and the slot,
push hard on all the sockets, and try to boot the Quantum (again at the end of 
the daisy chain) with no luck.  

Next, I check the connectivity of the ribbon cable on my SCSI card with a
multimeter, and everything checks out OK.  The card goes back in the computer,
but the boot fails again.  

Finally, I throw up my hands for about a week, and then assemble the whole
system again, and things fail again.  But then, I boot the SCSI utilities disk
that came with the SCSI card and it sees all SCSI partitions (Copy II+ failed
to see any of the partitions a week earlier).  Then, I change the control panel
back to booting from slot 7, and this time everything works perfectly.

Some of this is probably extraneous, but I didn't want to leave anything out.
Does anybody have any suggestions as to what's wrong with my system?
