Recently, I was able to create two partitions in different formats with the help of a few MR members. Everything is working great with that, but everytime I plug in or turn on my external drive, both volumes automatically mount. One volume is used to backup the entire HD in my PowerBook, so I only need access to that volume once or twice a month when I do my full backups. Usually when I plug in my drive, I open Disk Utility and unmount the backup volume (because right-clicking it's desktop icon and selecting "Eject" unmounts all volumes on that drive), so I was wondering if there is a way to make it so only the storage volume I created mounts when I plug in the drive? This way when I actually need to use to backup volume, I can mount it in Disk Utility. Not a huge deal, but I figured it was worth asking.
