Using both internal connectors at > the same time as the external one is just asking for trouble. Let me just echo this claim. Back when I was somewhat younger and less experienced in the ways of SCSI, I tried to do this for the simple reason that it's the obvious thing to try when you have both wide and narrow peripherals in the box (like a wide drive and narrow cdrom), an external device like a scanner and absolutely no conception of how the internal busses are actually wired. What happens then is that you create a "Y" in your SCSI chain, with two terminators on one end, and the fact that it worked for me at all for 5 months until I got another drive for the wide chain and totally pushed things past their limits is, frankly, pure amazing luck. - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
