I have been searching around here and online but can't find an answer (maybe because it is late and I am not thinking straight about what words to use) so I thought I would ask here. I have an external drive that contains 2 partitions. When I start the computer or plug in the external drive both partitions auto mount onto the desktop. Is there a way to disable this? Preferably for only one of the two partitions. If you care why I am doing this, one partion (the one I want to auto mount as normal) is for TimeMachine. The second partition (the one I do NOT want to auto mount) is simply for utility/extra storage that I would like mount via Disk Utility only when I need it. Thanks for any suggestions.
