When our daily tasks include the support and management of users and infrastructure at IT level, there are certain parameters that we must keep in mind to improve the performance, integrity, availability and security of not only the information but also of each object that is our responsibility.

One of these topics is associated with partitions that can be established for different reasons, either security or administration. Most of us know that creating a partition is to divide the disk, logically, into two or more parts, technically known as volumes, which are independent of each other and each can be formatted with a different file system .
There are several reasons why we can create a partition on a hard drive, some are:
- Possibility of installing an operating system on one of these partitions
- Create a backup unit in case of an error in the main unit
- Distributing the hard disk space more optimally
- Defining one of the partitions for Time Machine
Now, we must understand that if we have the backing of confidential and sensitive information on the same hard disk we may be exposed to a damage to the disk that will affect all partitions including that of our backup, so for backup issues it is best to use a different disk.
Before beginning any of these processes, it is important that we make sure we have a complete backup of all our files on the hard disk and documents , so as not to take any risks in the event of any failure in the process. In Mac have no need to have any program to create our backup because with Time Machine application that comes by default, we will be able to do it directly.
Once this is done, we can start the process to create or add a partition on the Mac hard disk
1. Create partition in macOS Sierra
The default tool on any Mac operating system to manage the entire partition theme is Disk Utility. To access it we can use one of the following options:
- Directing us to the route Ir / Utilities / Disk Utility
- Enter the term utility in Spotlight and select Disk Utility in the displayed option
- Use the key combination Shift + Command + U and in the popup window select Disk Utility
⇧ + ⌘ + U
Keeping in mind the purpose of the partition we proceed to select the disk on which to create the partition and select the Partition tab located at the top, the following window will be displayed.
There we can see how the disk structure is at the level of partitions and available space. To create our partition we will click on the + sign and we will see the following.
We must drag the flag to define the size of the partition or we can enter it manually in the Size field. In addition we can define the name of the partition and the format with which it will be formatted.
Specify the name and size:
Within the Format field we have the following file system options:
Once these values are defined, click the Apply button to start the process and we will see the following message:
Click on Partition to start the respective creation process of the partition in macOS Sierra. We can see that the partitioning process has completed correctly. From this moment we will be able to make use of the new partition in macOS Sierra
Disk Utility will be a great ally to create a new partition in macOS Sierra even if the operating system has not been installed, in this case we must do the following:
- Turn on the computer and press and hold Command + R
⌘ + R
This option will boot macOS Sierra in recovery mode and there it will be necessary to access the Disk Utility to create the partition according to the requested requirements.
In case we want to delete or merge a partition , we have to perform the following process. It is also quite simple. In the first place we would have to repeat the same actions as detailed above. We would have to select the (-) button in this case and then apply for the changes to take place.
If we remove an existing partition, we will lose all the data we have stored on it.
2. How to Troubleshoot Hard Drives
When there is an error in the hard drive macOS Sierra offers us a tool inside the Disk Utility called First Aid which performs a detailed analysis on the disk for errors and if they exist it proceeds to correct them.
To execute the first help in Sierra we must select the partition to analyze and click on the First help button located at the top, we will see the following window:
Click on Run to start the analysis of the partition and once the process is finished we will see the respective results:
3. Configuration of RAID in macOS Sierra
Another of the great options offered by Disk Utility is the ability to configure and set up a RAID drive according to current needs. For this we go to the File menu / RAID Wizard
Using this option will display the wizard where we must define the type of RAID to use:
To know more about how to configure RAID in Sierra we can go to the following link:
In this way we can create and manage the partitions in macOS Sierra in an intuitive way thanks to Disk Utility.
