Did you check before or after you hooked up that second one ? Based on what you just said, you've just committed the first Sin of SCSI, having two devices on the bus with the same address. (the second, of course is improper termination) All of our simple script assume the main drive is unit 6. If you moved the jumpers on the drive, I sure hope you changed the scripts appropriately.

Sounds like both drives listened to the 'format yourself' command, and the Quantum was the first one to answer. >it said it was going to, so I didn't even have a chance to reboot the >machine before disaster struck. Way to go! The user should always be Actually, the prep script does are you if you want to continue before it preps anything. Just after it warns you that "Any information on the hard drive will be lost!" You must have hit return without reading the prompt. >given a chance to back out before critical information gets destroyed. >Similar things apply to the Install disk's HDFormat tool as well. It also tells you what its about to do, and give you a chance to say NO. You're main problem sounds like you've got two drive set to the same unit number. After you fix this, make sure termination is correct. And make sure all drives have reselection turned off. andy >+----------------------------------------------------------------------------+ >| Dallas J.
