How do i partition my hard disk ?

i have a macbook pro 13" (october 2013) model..it comes with a 256gb flash drive so i want to know if it is possible to partition my disk?
Thanks.

Of course. To partition the flash drive, use Disk Utility (in /Applications/Utilities) > http://pondini.org/OSX/DU3.html
As detailed in that website, open Disk Utility, choose the flash drive at the top of the sidebar and go to Partition tab, so you can add and remove partitions.
Note that, if you have installed Windows with Boot Camp, you won't be able to modify your partitions. Boot Camp doesn't allow you to have more than two partitions in the hard drive, apart from the EFI and OS X Recovery partitions, although there are tricks

At only 15 months of age, my MacPro crashed yesterday! Any idea how I can save my hard disk from being destroyed if I hand it in for repair?

Open it up. Buy a new replacement drive. Install Mac OS. Then give it to them if you still have trouble.
As for the install failing,
I never do the older "archive and install"
I format and initialize first, even zero the drive, and only then install.
of course all the data is lost.
Data Rescue 3 demo can scan a drive but you need to have setup a 2nd boot drive to work from, AND you would need part of that 2nd drive partition for recovery of data. 30-50GB system partition and 150% the size of the drive you want to recover.
TimeMachine I never adopted or liked but 350% and would only use as secondary backup with cloned copy of your drive.
Backups can be scheduled, run at night or weekend or both, a weekly clone and daily sets.
Disk Warrior 4.2+ is another $100 (DR3 is about same but demo is free to try).
A spare external drive case $30? and TWO hard drives, a replacement and backup/recovery $100 each?
Just some ideas to throw out there....
Bootable clones though you will find are very useful, handy.
I like the small 40GB emergency boot partition - put one on your TimeMachine drive etc.
LION: the one good thinig: it has a recovery mode partition and new Macs have "net install" feature and minimal hardware diagnostic over the internet to do Apple Hardware Test. Lion $30 and might actually want to install it on external.
So DO try installing OS X on one of your external drives - create 40GB volume just for that - if you can please.

Partitioning The Hard Disk

I wanted to how to partition the hard disk so I can have three partitions, i.e One for the Mac OS X 10.6 and applications, and one for the User files i.e all documents, downloads, music etc, and one for the bootcamp partition, I know how to partition, i wanted to how to move the user directory permanently into the second partition, this way if I ever have to reinstall the OS I dont have to back up my data, all the time.
Actually I also would like suggestions on whether this is a Good or Bad Idea, Performance wise?, and also whether this is possible?

Do you mean uninstalling software? If so see the following:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are also several shareware utilities that can uninstall applications:
AppZapper
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

Hello Everyone,
I have a MacBook older model with me.I am running 10.7.6 on that, I was trying to use BootCamp to install windows on my mac. Since BootCamp can only work on a single Volume, I partitioned my Hard Disk to one volume.
Using BootCamp I installed windows and everything worked fine. After installing windows and testing everything, I switched back to OS X and this time I tried to make another partition on my single portioned Mac volume and named it Backup. That too worked. Now I have three Volumes
1)Development2)Backup3)BootCamp.
Next when I switched to Windows, It should the classic error, No Bootable device found, please insert a Bootable CD and press any key. When I tried to enter my Mac OS X install DVD and by pressing option key, it does not show me the proper Mac OS X development volume. It keeps going back to the No bootable device found message.
Any help will be much appreciated
Regards
Mithun

you can't add a partition in between - you put Windows to a new partition number.
GPT (GUID)
EFI
Mac HFS
Lion Recovery
Windows
And now you have two HFS
One partition and one Windows (plus Lion Recovery).
If you were to have more, it can't be before Windows for one thing.

Partition in hard disk

i'm new in using mac book pro..
i'm wondering,, do i have to do partition in my hard disk? like when using windows?
thx be4

Some users of the Intel-based Mac computers had used the BootCamp utility to
partition a hard disk drive - if suitable free space in one large section existed -
in the computer. Since Boot Camp has (or had) the ability to do this, when the
partition was no longer desired, some of those same users had to use BootCamp
to remove the partition. Another option was to use Disk Utility to make partitions
on a new or wiped hard disk drive, and install whatever on those partitions.
And there is also some other means, where you can partition a drive that already
has a working OS on a section of the drive, without damaging the existing content.
Since I don't do that, I am at a loss in regard to more detailed information. My
external drives have partitions and some of them contain bootable clone content.
Good luck & happy computing!

How can i partition my hard drive with lion on it and install snow leopard from time machine

How do I partition my hard drive which has lion on it and reinstall os6 from my time machine?

You going to need a second harddrive. It is riskie to resize your haddrive with live data on it. You need a backup of the data. That said, you might as well copy your data to the second harddrive. Repartition. Then copy the data back. I bought a 128gig flash drive from walmart for $32.
There were repartition commands introduced in 10.4.6 to repartition the harddrive.
For what it is worth, you can non-destructively partition a harddrive from single user mode in 10.4.6 or greater. Of course, you should have a backup of the harddrive.

How do i erase my hard disk

How do I erase my hard disk to prepare for resale?

Prepare Your Mac for Sale
Boot from the OS X Installer Disc One that came with the computer. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select the startup volume from the left side list then click on the Erase tab. Set the format type to Mac OS Extended (Journaled) then click on the Options button. Select the one pass Zero Data option and click on the OK button. Then click on the Erase button.
Note: You can skip the Zero Data option if you are not concerned about removing sensitive personal data from the hard drive. If you choose to skip this part of the process then it is possible for others to recover data from the hard drive. The Zero Data procedure will prevent others from getting access to your personal information.
This process will take 30 minutes to several hours depending upon the size of the hard drive. After formatting has completed quit DU and return to the installer. Now complete the OS X installation. At the completion of the installation do not restart the computer. Instead just shut it off. The next user will be presented with the Setup Assistant when they turn on the computer just as it would if new out of the box.

How can I erase my hard disk with OS X 10.8.2?

If you want to erase the hard disk and reinstall OS X, follow these steps:
1. Back up your data to an external disk if you don't want to lose everything. When you erase a hard disk, everything is deleted.
2. Press Command and R keys while your Mac is starting to start into OS X Recovery, and open Disk Utility.
3. Select Macintosh HD on the sidebar, go to Erase tab and erase the disk.
4. After erasing the disk, close Disk Utility and reinstall OS X, so OS X will be installed with factory settings.
Don't forget to install iLife applications after the installation, if you need them. They come in the Applications DVD (if your Mac came with Snow Leopard or older), or open App Store > Purchases and download them

You figure out how to do it on your OS using C/C++ code.
Then you write a wrapper in JNI to call your C/C++ code.
