The need for removal of the free space blocks, while partitioning a Mac drive may occur due to the following situation. When the inbuilt Disk Utility for Mac fails, then the need arises to use professional Partition Managing Software, which knows how to partition mac drive, along with removal of free space blocks and which takes care of the issues, not resolved by Disk Utility.
There are two partitions on the Mac drive, which were made with the Disk Utility. If the user has a router, which has NAS option and that do not support a partition. There is need to remove partition kept as a backup and to create one single partition. But, the user faces the error:
“this partition can’t be modified.”
He is unable to delete or resize this partition
This error condition will arise when The Mac was of type MBR and not GUID
The user needs to check on this and if the type is MBR, the resizing option cannot take place. If the Time Machine Encryption is turned on, then File Menu in Disk Utility can unlock the partition.
If nothing works out to resolve such a situation then, the way left out is the formatting of such MBR Partitions.
However, there are some tools or professional software, which converts, without any such situation of data loss. The resizing can be done, only by reformatting the partition to GUID. This will lead to erasure of the data residing there.
There are other situations like shrinking the Mac OS X partition, so that the personal files of the user are all stored separately from the OS files. Another situation is the expansion of the boot volume of the Mac for the purpose of adding more free spaces or installation of more programs. This will be required for the improved performance levels. So, the resizing is often needed for a partitioning or repartitioning type of task.
Disk Utility, is an in-built facility with Mac, which can easily resize the partitions. It can also delete, format or create partitions. The Mounted volumes can also be resized and there is an increase or decrease of free space. This is called “Live Partitioning”.
Disk Utility with Mac OS X 10.5 and later, will allow the resizing, without any need to even erase the data residing on the Mac drive.
Live partitioning can also pose a risk in the form of Data Loss. The process of resizing of the partition with Disk Utility is very much streamlined and if one-step is missed somewhere, a data loss situation will arise and the user will compromise with the valuable data that generally resides in the Mac.
If there is need for the increase a volume size, then the partition below the volume need to be deleted. So, there will be a creation of data loss situation. However, a resizing or expansion will not lead to losing any data on the disk volume.
Now, format and partition Mac can be a problem, when Disk Utility is used for partitioning. This will be due to limitation of Disk Utility to partition properly, when there are free space blocks on the Mac drive.
Partitioning can always be a problem, when the data resides on the partition. So far Macs are concerned the resizing option for the Intel based Macs makes this task absolutely easy. However, there is a certain limit for resizing of the partition.
Resizing is often required and Disk Utility will achieve this for the user. The partition fails to be extended, when there is no free space existing between this partition and the consecutive partition. We have also discussed that Disk Utility fails in the resizing of the MBR partition.
There is sometimes the need for enlargement of the boot volume, for meeting the objective of installing more applications. Although Intel based Mac allows this to be done very easily. However, issues get created, when the user attempts this in Disk Utility. In fact, Disk Utility will not list the free space along with other partitions.
If these types of situations arise, then what is needed is the help of a professional software. This will enable the user in the resizing of the partition. The overall free space on the Mac drive is utilised for either the shrinking or the expansion of the Mac partition. The resizing of the MBR type of partition is also made possible with this software.
The software will have options like Shift and Resize, when the partitions can be moved or there are additions of a number of free spaces, for the creation of a new partition. If some unused partition exists on the hard drive, then a new partition can be formed, after formatting of deleting the older ones.
Another good feature of the Partition Managing software is that it will always show the free space, where the existing Mac volume was deleted.
The software generally offers safety and privacy to the users, by hiding and revealing the partitions. The software also offers additional features like formatting the Mac drive. This situation will be encountered when the partition becomes absolutely corrupt and is unusable or the partition need to be organized, with the erasure of the data, so that all the unwanted files are removed from the partition. The partition then can regain a reusable condition.
