A few months ago I installed a 1TB Seagate SATA (PN: 9BX1A8-570) as a storage drive to my Mac Pro (in HD bay #2) running Leopard and it worked fine. The other day, I bought another identical drive and installed it as an additional storage drive (in HD bay #3) and it mounts fine, but the one in bay #2 doesn't. So I physically removed the new drive, and the old one mounts fine. It appears that if both drives are installed, only the one in bay #3 mounts. How can I make sure both of these drives mount correctly?
