We open the folder and look for a file called 'testdisk' with a Terminal icon. By double clicking on it, it is unzipped and creates a folder called, at the time of making this post, 'Testdisk-6.14'.

Now to run TestDisk, we will have to open the file that we have downloaded.This is a deleted file and partition recovery application. We download and install TestDisk from CGSecurity page.In the event that we want to use an application external to OSX, the steps to follow are the following:

Now, at the bottom of the screen, you must click on Verify and repair disk permissions. Within the window that appears, we select on the left the disk on which we want to work and click on the upper tab 'First aid'. Now we turn to Launchpad and enter the OTHERS folder, to be able to click on Disk Utility.We close all files and applications that are using the disk, since it is very important that it is not accessed during recovery.In order to recover the partitions without having their data, we can make use of applications such as the ones we present today, one present in the Apple system, Disk utility and the other TestDisk.

The point is, that can be done quickly if you had copied the values of the different partitions, otherwise, things get complicated. When it comes to recovering an HFS partition that we have deleted by mistake or it has become corrupted, we have to rebuild the partition table to be able to leave it as it was at the beginning. HFS, are the initials that represent 'Hierarchical File System', which precedes the one used today by Apple computers, the Plus HFS. Now, we always run the risk that if we are playing with the creation of partitions, at any given moment we can delete one that contains data and we are dumbfounded at the impossibility of being able to recover it, in those cases we will say that we have deleted the HFS partition table Within the OSX system it is possible, in a very simple way, to create and delete partitions dynamically. Many of us are users who at some point have used the Disk Utility tool to manage the partitions present on our hard drive.
