SCSI host adapter cards

How would the type of card affect the troubleshooting processes you would use to discover if the device was faulty?

Card with an on-board BIOS: Use the config/diag utilities that are in adapter BIOS. E.g. Adaptec cards will show "Press Ctrl+A for adapter setup" or somehting, during POST
and this gets you into a setup facility.

Cards without an on-board BIOS: You'll need to use diagnostic software.

The newer SCSI cards have electronic termination built-in; the older ones required a physical terminating resistor for the cable.  Same thing for setting unit IDs: older ones have DIP switches or blocks, new ones are set in the configuration program.
If the card is Ultra or Wide compatible, I would try decreasing the speed in the BIOS (assuming the card has BIOS such as the Adaptec 2940 series, as rid mentioned) for the SCSI ID of the device you're having trouble with.  I had a problem with my 2940UW and a CD-R (not RW!  this is wayyy back, 4X burn!) and solved it by turning the SCSI speed (MB/s) from Auto to 5MB/s or so.  Got the solution here at EE by the way...
