Janice, As has been mentioned earlier, you need to give it a different SCSI ID number than anything else on the bus. Your original drive will be 0, the CD 3, and 7 is the computer (actually it's the SCSI controller on the motherboard). The boot drive does not have to have an ID of 0. The boot drive just has to have a valid System Folder, and be "Blessed'. I generally have a valid system folder on each hard drive, just in case my boot drive flakes out, etc. Only one item on the SCSI bus can have termination, and that item must be connected at the end (physically) of the ribbon cable.
There may be a couple of other issues too. If it were me, here's what I'd do. I'd disconnect the original drive and install the new drive with ID set to 1 and termination installed. Then boot up from the Apple install CD, format and install the operating system, reboot and see if it boots up successfully. If all goes well, you know that there is nothing wrong with the drive itself, and you then just power down, remove the termination on one of the drives and install the drive with termination at the end of the ribbon cable. Reboot from Apple CD, and then choose the drive you want to boot from in the Start Up control panel and reboot. I mention this because the SCSI I just bought, and am now returning, won't show up on my built in SCSI bus, but will on my SCSI card. It also can't be formatted with Apple's drivers.
