How to Overcome Various Challenges in Resizing Mac Partitions

Disk partitioning and resizing is required to store and mange large volume of data on your Mac. Adding new partitions or resizing Mac volumes can be easily done by using the Disk Utility feature provided with the Mac. The tool helps in performing various operations like Adding, Resizing, and Deleting of the partitions without causing any data loss.
Difference between Partitions and Volumes.

  • Both partitions and volumes are part of hard drive storage space. However, they differ in the manner they are created.
  • Volume is a logical object generally made up of single hard drive partition and is formatted with a file system. However, it can have multiple partitions.
  • Partitions refer to separate sections that are created physically on the hard drive. Such specific section or area of a hard drive is called a partition.

Limitations of Disk Utility while Resizing Mac Partitions

Disk Utility is considered to be an ideal inbuilt tool to partition and resize the volumes on Mac; however, there are certain limitations with this utility. While working with Disk Utility, you can reduce the size of any existing volume, but you cannot increase the size of a volume if there is not enough space between the volume and the next partition. Disk Utility only allows increasing the size of a volume if there is enough free space between them.
Such a situation creates a risk of losing data, as you might need to delete the next partition to increase the size of the volume. If you have a backup of your data and there is a need to increase the volume of a partition, you can delete the partition below that volume. However, you would not lose any data from the volume you are going to expand.
Partitioning is not limited to hard drives with user data. You might need to partition a boot drive having important system files. Partitioning a boot drive is considered to be a risky process, as it requires the movement of bootable files. Any issue while moving the bootable files could make the boot volume corrupt, leading to boot failure. In order to overcome all such limitations and shortcomings, it is advised to use a professional and trusted tool.
