I have an external drive that is permanently hooked-up to my iMac via Firewire. I use this drive only to perform a bootable disk image of my hard drive at regular intervals using the CCC scheduler. The backups are performed only once a week. I would like that this backup drive not be mounted when I or anyone else logs in to the computer. It annoys me to hear the drive turning and vibrating until it spins down and seeing it's icon on the desktop. Is there any way to prevent automount of this particular drive? I know I can dismount it manually using Diskutil, but I want everything to be automated. Any clue as to whether CCC will mount it when needed if it is unmounted? Thanks for you help and insight!
