Mac OS X users use several partitions to keep all their data on their Mac systems. Apart from initializing a Mac hard drive also require some new partitions and therefore the requirement of resizing the existing partition takes place. Mac computers or Mac Hard Drives are initialized in the factory itself and you do not have to worry about the initialization process. In Mac OS X, there is a inbuilt Mac Tool called Disk Utility that can be used to delete an existing partition, format or resize a partition. However people sometimes either unable to find the disk utility in their Mac system or even they found it, they don’t easily operate it to Resize Mac OS X partitions. A simple alternative to this is to use some third party Mac partition manager software.

Steps to Resize an existing volume on Mac OS X

Using Disk Utility existing volumes can be resize without losing data but there are some limitations too. Disk utility is able to decrease size of any volume but it can only increase the size of a volume if there is enough space available between the volume that you want to expand and the next partition on the hard drive. It means if you want to increase the size of a volume then you first need to delete the partition below that volume and you will lose all the data on the partition that you delete so first of all before doing that you should take the backup of the volume, but you can expand the selected volume without losing any of its data.
