Resizing Mac partitions after its initialization is a simple task and achieved prolifically with the help of a disk utility like Stellar Partition Manager. All you need to do is open disk utilities from Application<<Utilities folder and select your chosen hard drive for size adjustment. In this tutorial we will show you how to go about resizing Mac partitions and what are the things you need to watch out for before you do it.
Doing so is simple and can be explained with the help of the below disk utility diagram:
Resizing Mac Partitions
1. Select HD for partition from left menu.
2. You can rename the partition just like I named it 'Tom' from 'Untitled 1'.
3. Set the size for the partition in two ways, either enter the number like 50 (GB) in the box, or else use the mouse drag to resize the partition manually. Do so whichever way you like. You can minimize the free space by allowing the second partition to occupy more of the hard drive space.
4. When everything is set, just hit the Partition button to actualize your settings. The resizing of partition may take time depending upon the size of the hard drive, so be patient.
Roadblocks while Resizing Mac Partitions
Now come to the real deal in securing hard drive data against any possible blunder that might happen when you resize the hard drive.
Abrupt system shut-down: Trust me, the activity involving resizing or partition of a HD is most susceptible to errors in case of sudden Mac shutdown. The shutdown may be due to power fluctuation, bad battery or any other system failure.
Bad blocks: - Bad blocks on a Mac hard drive can cause huge pain for the Disk Utility to complete the partition & resizing activity accurately. The bad blocks are difficult to resize so they will tend to freeze up Mac OS X and halt the process. Unfortunately, no inbuilt feature of the disk utility would let you know about the presence of bad sectors on the hard drive. Users who suspect this of their Hard Drive must confirm with the help of a Surface Scan tool.
Also, users won't be able to partition the startup-disk of the Mac OS X while booting from the same disk. If you seek to split /resize your Mac boot drive in case you find lots of space being unused, then take the help of the boot DVD to do so.
Stellar Partition Manager is one of the best partition resizing tool for any Mac hard drive as it comes with features to undo any partition activity and hide a partition.
Backup before resizing a partition: - Backing up a Hard Drive is not a task to be performed only before resizing your drive but it’s a timely activity which helps maintains sufficient resource of your hard drive during any disaster.
