We've suffered our fair share of SCSI problems, and can pass on some
advice - Check your cabling and termination! In my experience, most SCSI
errors are caused by bad cables (too long, poor connectors, etc) or
broken/missing/duplicate termination. Besides, cables and terminators
are cheap compared to adapters and drives! :-)
