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. 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. 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.

Some Macworld readers are concerned about upgrading to macOS High Sierra, which offers the new APFS (Apple File System) that replaces the nearly 20-year-old HFS+ filesystem. APFS offers a lot of advantages for SSD performance and durability, as well as encryption for any type of drive. But it’s not backwards compatible with older versions of OS X or macOS. You’re required to upgrade any SSD startup volume when you install High Sierra—there’s no way to prevent it. There was a choice to bypass migrating to APFS while installing High Sierra during the beta period. However, Apple removed that checkbox for the final release. (An earlier version of this article misstated that the checkbox remained.

My apologies.) This shouldn’t be a problem, because it’s unnoticeable, but it might be a reason for you to delay moving to High Sierra if you have an SSD boot partition and want to make sure no APFS issues emerge for other people. It’s rarely a bad idea to wait for macOS 10.X.1 or even 10.X.2. Apple isn’t automatically upgrading Fusion drives, the combination of SSD and hard disk drive (HDD) that it’s popularized for higher-capacity systems, because SSDs remain quite expensive above 512GB. Apple hasn’t said exactly when a Fusion APFS upgrade will be ready. However, we expect that because there’s no upgrade choice for APFS with High Sierra, the Fusion upgrade will also be mandatory when it ships. How to upgrade to APFS in Disk Utility If you want to upgrade an external SSD to APFS, you can do so via Disk Utility. Disk Utility also supports external hard drive conversion, but there’s no advantage, so I’d recommend against it at this time.
