    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.

    i don't know how to stop auto-mount...

    ...but what exactly is wrong with having it mounted all the time? you can just adjust finder to not show it on your desktop if you don't want to see it

    doobs, Thanks for the reply and suggestion. The main reason I didn't want it to auto mount is to reduce the amount of potential confusion my wife (who isn't the most savy) may have. Not to mention trying to keep the desktop clean. Between the internal HD, iDisk, these 2 partitions and the storage on my airport extreme there are a lot of friggin' drives.

    But you bring up a good point in that I don't think I mind if the second partition is mounted as long as it is hidden (shouldn't use too much resources sitting there idle). How do I hide a single drive in the Finder? If it is obvious I am sorry, maybe I can use the "late" excuse again?:), but I can only see where you can exclude ALL external drives.

    Thanks again.

    You can drag the drive off the sidebar. Poof, it's gone.

    By the way, you can also use Disk Utility to unmount the drive, the next time you start the computer (why not sleep?), you shouldn't see the drive.
    If you want to mount it again, you use Disk Utility again.
