    I have a Mac Pro with 5 internal Hard drives. I just wanted to know if there's a way of setting it so when I boot up certain hard drives are set to the 'unmount' rather than 'mounted position as the default setting?

    Many thanks

    Yes. Create a file '/etc/fstab' with lines such as the following:

    UUID=00000000-0000-0000-0000-00000000000 none hfs rw,noauto
    The zeroes need to be replaced with a correct UUID for the volume
    you do not want mounting. 'diskutil info volume-name' will show
    you the UUID.

    Great to know it's possible. How do I make a UUID? Is that something I would do in terminal?
