    I am about to upgrade the HDD of my MBP 13", I heard that there is a software called SuperDuper which can make clone of the HDD, so if I put the new HDD in an enclosure and use the software to make a clone of my current HDD, then I replace the HDD, press the power button and it will be exactly like the system(bootable OS, documents, pictures, music, everything) before, except the capacity is larger? And do I need to format the new HDD first?

    Thanks a lot!

    Yes, SD can make an exact clone. I suggest you:

    1 attach new drive in external enclosure and format it with Disk Utility
    2 clone your internal drive to the external with SuperDuper
    3 reboot and startup from the external
    4 check everything's working ok for a day or so (it will run a bit slow, being external)
    5 swap internal and external drives
    6 boot normally from your (new) internal.

    Hold down the option key when you boot and you will get a screen showing boot um, options. :D
