    Hi, I just bought a macbook and i like to partition it to OS volume and data volume.

    Back in my windows days, I did a partition while formatting the drive.
    Now using mac, I dont know how to parition it.

    Please guide me how to do a parition and where to get the necessary program if needed.

    Thanks in advance

    you partition it with Disk Utility, but you can't do it while booting from the volume. Why do you want a separate data volume?

    IIRC, you will need to re-install osx as partitioning will wipe it.

    i want separate so that when i do upgrade for the OS or anything, i dont hv to shift my data around.

    So where can i get the OS recover disk?

    I believe the recover disk can let me to parition on the drive.
    Otherwise i hv to buy the next version of OS cos my OS now is 10.8.

    You don't have to shift data around when you upgrade. Your backup will take care of any unlikely problems that the upgrade may cause.

    Normally i will keep a copy of the data i am working with in the HDD then another copy in a portable HDD as backup.

    The reason for parition is I dont want any pp to go the the main drive and disturb the OS file. There is also chances that our data file mixed with the OS file etc...

    All these can be overcome by creating folders. But it will get very messy if alot of users and folders.

    OS X can non-destructively resize the main partition even while you are booted to it. Just follow this guide to use Disk Utility for the task. After you have resized the main partition you can follow this guide to add a second partition.

    Backup first just to be extra safe in case you make a mistake. :)

    That said, you really don't need to make partitions like this in OS X. By default it keeps user data and the OS pretty well separated.

    Hi, thanks for the reply.

    So that means i dont need a clean installation to do a partition.
    That is great.
    Anyway, I will try this weekend otherwise I will just proceed with my other installation.

    Don't quite understand this. Normally, you keep people out of the system folders by the Unix system of permissions and groups. Data should be in the user accounts, nowhere else.

    A partition of this sort is an artificial limitation which will almost certainly needs to be altered at some point in the future.

    Hi thanks for pointed out the unix system permissions.
    I have 3 accounts in the system
    1) the admin that is me
    2) my wife, also admin
    sometimes she use the system and would like to install or do any things
    if she is not admin account then i hv to log in and out to do it.
    putting my wife as admin so i dont hv the trouble for the system to prompt me any restriction
    So partition add as an prevention for her
    3) the guest account where user permission is needed.

    Anyway i had successful done the partition on the only HDD.
    Thanks all for pointing out.
