How to Partition your Mac’s Hard Drive or SSD There are basically two ways to disk partition your Mac: First is using Bootcamp and other is with the help of Disk utility. Let’s discuss both of these ways in detail.
Windows marks Dynamic drives with a green color. Resize Partition in Linux. Primary way of resizing drive partitions in Linux is to delete the old one and create a new partition, using the previous starting sector (you can think about it like “left bound of the new partition”).
Using Bootcamp If you’re willing to run Windows on your Mac, then this happens to be one of the most simple and powerful ways to partition hard drive on Mac. Mac’s inbuilt Boot Camp assistant eases down all the process and guides you with simple on-screen instructions. Once you through with the process, you can run both operating system (Windows and Mac) on your MacBook. But apart from this reason, if you want to partition your Mac’s hard drive then you can use the second way which is via Disk Utility that we’ll be discussing in our next section.
Using Disk Utility If you’re sole purpose is just to partition your Mac’s hard drive, then using a disk utility manager might be an ideal choice. Disk utility acts like a smart Mac Partition manager and is a useful in-built Mac application that sits within your Utilities folder, inside Applications folder. Before your start up with this process, just make sure that you back up all your important data, create a clone on your entire hard drive, just in case anything goes wrong. Here are a few things you might want to consider before you jump on partitioning your Mac’s hard drive via Disk utility. Clone your Mac’s hard drive. To double check whether this clone works or not, plug the clone in and go to System Preferences Startup Disk. In this way you can make sure that the cloned drive is successfully working, and you can proceed to partition your Mac’s hard drive without any worries.

Now select your Mac’s internal hard drive name. Tap on Partition.
Tap the ‘+’ below Partition Layout. Once the new partition appears, you can change the size of both disks accordingly. Assign a name to your newly partitioned disk drive. Tap on “Apply” to save changes. Read this to know how you can secure your Mac as it is important to keep it in mind if. If you’re unhappy with the disk partition, you can anytime revert back to old state.
Tap on “Revert to un-partition hard drive” option on Mac.

So fellas, here was a quick guide on how to partition a hard drive on Mac.

It can be used, for example, to install different that do not use the same file system. There will, therefore, be at least as many partitions as there are operating systems using different file systems.
If you are using just one operating system, a single partition of the full size of the disk is sufficient. That is unless you want create several partitions so as to have, for example, several drives on which data is kept separate. There are three types of partitions: primary partitions, extended partitions and logical drives. A disk may contain up to four primary partitions (only one of which can be active), or three primary partitions and one extended partition. In the extended partition, the user can create logical drives (i.e. 'simulate' several smaller-sized hard drives). Here is an example of where the disk contains one primary partition and one extended partition made up of three logical drives: For systems (DOS, Windows 9x), only the primary partition is bootable and is, therefore, the only one on which the operating system can be started.
Master Boot Record The boot sector (called the Master Boot Record or MBR) is the first sector of a hard drive (cylinder 0, head 0, sector 1). It contains the main partition table and the code, called the boot loader, which, when loaded into memory, will allow the system to boot up.
After it is loaded into memory, this program will determine from which system partition to boot, and will start the program (called the bootstrap), which will start up the operating system present on that partition. This disk sector also contains all of the information concerning the hard drive (i.e. Manufacturer, serial number, number of bytes per sector, number of sectors per cluster, number of sectors, etc.). This sector is, therefore, the most important one on the hard drive and is also used by the setup to recognize the hard drive. In other words, without it, your hard drive is useless, which makes it a favorite target for. File Systems In this section, it is important to differentiate between the FAT file system and the file allocation table (FAT).
FAT is the name of the file system used by DOS operating systems (DOS and Windows 95, as well as Windows NT and OS/2, which support it). Operating system Associated file system FAT16 Windows XP NTFS FAT32 FAT16 - FAT32 (for version OSR2) NTFS OS/2 HPFS Linux Ext2, Linux Ext3 FAT file systems are characterized by the use of a file allocation table and clusters (or blocks). Clusters are the smallest unit of storage in a FAT file system.
A cluster actually represents a fixed number of disk sectors. The FAT ( File Allocation Table) is the heart of the file system. It is located in sector 2 of cylinder 0, head 1 (and is duplicated in another sector as a precaution in the event of an accident). This table records the numbers of the clusters that are used and where the files are located in the clusters. The FAT file system supports disks or partitions up to a maximum size of 2 GB but only allows at most 65,536 clusters.
So, whatever the size of the partition or disk, there must be enough sectors per cluster so that the entire disk space can be contained in these 65,525 clusters. As a result, the larger the disk (or partition), the greater the number of sectors per cluster. The FAT file system uses a root directory (represented on the operating systems that use this type of file system by the symbol C: ), which must be located at a specific location on the hard drive.
This root directory stores information on the sub-directories and files that it contains. For a file, it will store the file name, the file size, the date and time the file was last modified, the file attributes, and the cluster number at which the file starts. Using Multiple Partitions As mentioned before, there are three types of partitions: primary partitions, extended partitions and logical drives. A disk may contain up to four primary partitions (only one of which can be active), or three primary partitions and one extended partition. In the extended partition, the user can create logical drives (i.e. Create the impression that there are several smaller-sized hard drives). Primary partition A primary partition must be logically formatted and have a file system appropriate to the operating system installed on it.
If you have several primary partitions on your disk, only one will be active and visible at a time, depending on the operating system with which you started the computer. By choosing which operating to load at start-up, you determine which partition will be visible. The active partition is the partition from which one of the operating systems was loaded when the computer was started up. The partitions, other than the one from which you started, will then be hidden, which will prevent their data from being accessible. The data on a primary partition are therefore only accessible from the operating system installed on that partition.
Extended partition Extended partitions were developed to overcome the limit of four primary partitions, as you can create as many logical drives as you want in them. At least one logical drive is required in an extended partition, as you cannot store data in them directly. Many machines are formatted with one large partition using up all available space on the drive.
This is not, however, the most advantageous solution in terms of performance and capacity. The solution is to create several partitions, which will allow you to install several operating systems on your disk, save disk space, increase file security, and organize your data more easily Here is what a system containing several operating systems looks like: Free Software to Partition Your Hard Drive There are many free programs that can help you to partition your hard drive. Some of the most well-known ones are,. Image: © ladyann - 123RF.com.
