To increase the system performance, you may partition the Mac hard drive. Partitioning a hard drive means dividing the physical hard drive into two or more different logical groups. If you have two or more partitions then you can easily install Operating system on one partition and data into other partition of same hard drive. You can also easily encrypt your private data by encrypting a single partition, which contains your private data thereby avoiding unauthorized access by the other people. Before creating multiple partitions, you should know the size of hard disk. Based on the capacity of the hard disk, you can create number of partitions you want. Using disk utility you can create, delete and rename the partitions. While creating partitions, you may come across partitioning errors, which may results in data loss. So you may try to repartition the volumes to get the data. Sometimes situation occurs where you can even lose data from repartition the volumes. If you come across such situation and want to know how to recover repartitioned volumes and data, it can be possible using partition recovery utility that can recover lost data from partitions.
While doing partition, you can select either HFS (Hierarchical File System) or HFS+ (Hierarchical File System) file system. File system is essential to organize and manage the data in an appropriate manner. Sometimes, file system conversion may also results in data loss. Because, once you have converted the partition from HFS to HFS+ file system then, you cannot be able to convert the partition back from HFS+ to HFS file system. If you want to restore partition to HFS file system, then you need to re-format the entire partition which may results in data loss. Re-formatting a partition convert the file system, erases complete data and assigns a new file system so, when you try to access the data from the re-formatted partition then file system may not be able to provide the requested data. Sometimes, file system conversion may also results in file system conversion errors, which may not allow you to do the partitions.
Although creating or deleting a partition from hard drive is simple and easy, it should be done carefully. If you delete wrong partition then there may be chances of data loss so, if you want to delete a partition then you have select the correct partition, which you want to delete. To protect data from such problems you should have backup. The moment you find that you have lost the data then, avoid saving or copying new data on affected partitions, which may overwrite the data resulting in permanent data loss beyond the recovery. If you have not created backup, then you can use data recovery software to recover data from formatted or deleted partitions.
