I have a 1742 and it is humming along without incident. %uptime 1:30PM up 5 days, 5:03, 4 users, load averages: 0.17, 0.15, 0.24 Don't let the load average fool you. I have been doing some number crunching which produces data files from 1 to 10 MB in size. I also rebuild the entire source every week. I have 2 drives (Quantum and Maxtor) and a HP DAT hanging off my 1742. > Termination has been checked, this system ran BSDI before without trouble. > SCSI bus is known good.
