The backup process still causes my machine to lockup... FWIW, I have an 8505XL on a 2940UW (also an Archive DDS changer). I don't have any trouble with them. Admittedly, I'm a diehard tar user, but I can't imagine that's the problem. Are you 100% sure your termination is OK? I've found the 2940 to be very particular. For example, I *could not* get it to work with specific combinations of disks, though I'm sure that there is nothing wrong with the disks. I now have two 2940s in my machine, with some disks on each, and it works fine like that. Greg
