Mac drive partitioning problem can be a tension to most of us. but you can create multiple partitions of your Mac hard drive with Disk Utility. This utility is free and comes with Mac OS X 10.5 or later version. The steps do not vary much with the changes in version. Among some of the notable features, Disk Utility has the ability to add, delete or resize partitions but all without erasing the hard drive.
We need to discuss the limitations of Disk Utility. Sometimes, the system partition needs to be shrunk on the Max OS X hard drive so that personal files are stored other than the Operating system files. We also need to increase the boot volume area on Mac to install more programs or there is an addition of free space for the improvement of performance. Apart from this, we need resizing for the purpose of disk partitioning or repartitioning.
Solution for the Mac Drive Partitioning
The resizing option becomes easier with the inbuilt utility in Mac called Disk Utility. Disk Utility allows not only Mac drive partitioning but also aids in the modifications of the partitions; in the form of addition, deletion and formatting of partitions. The mounted volumes can be resized with Disk Utility for a preferential increase or decrease of free space. This is called “Live Partitioning” in Mac which needs to boot from an installation disk or an external drive with pre-installed Mac OS X.
One limitation, which appears while using Disk Utility, is that we cannot extend partition, if there is no existing free space between the concerned partition and the next one. Another issue is Master Boot Record partition, is not done with Disk Utility.
In such cases, a professional Mac Partition utility can be used for solving such problems related to Mac Drive Partitioning. The software is also supportive of resizing partitions formatted by MBR. The expansion and the shrinking of the partition can be done by utilizing the overall free space of the drive. These software can resize Mac partition on any drive by adjusting and reorganization of the free space, thus making the operation secure and free from the risk of data loss.
However much improvements are being made to Disk Utilities, certain errors cannot be fixed by it. Disk Utility often shows the error;
“Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.”
For fixing such errors, we need powerful tools. The professional utilities offer something more than the conventional disk repair facility.
Damaged directories are the major cause for Disk Problem. Most of these professional software can rebuild the hidden directories, where the data is actually stored. Some of the software have the backup option for the healthy directory, so that recovery becomes faster, while the directory gets damaged. Sometimes a separate bootable partition can also help in the event of the disk repair without the need for a separate startup disk. They can also find bad files and defragment files and volumes.
The format and partition checking routines run by Disk Utility can be run from multiple locations on the hard drive like the Main Boot drive, Recovery partition and Alternate Boot drive. These approaches often do not show the same results. The drive can be shown perfectly fine in one case like when Disk Utility is being used on the boot drive, but in another case when run from the Recovery drive, the same drive shows needing repair. Rebuilding the affected drive can be a solution, even when the Professional software claims that it has repaired the problem. This will lead to backing up the files and then full repartitioning and formatting the drive and finally restoring the files.
