If there is a problem with the Disk Utility application on your Mac, then you can try to do the same via Terminal. It is a cleaner approach to erase a disk and would help you meet your requirements easily.
Step 1. To start with, go to Finder and navigate to Applications > Utility to launch the Terminal app as an administrator.
Step 2. Once the Terminal application is opened, just type the command "diskutil list" and press return. This will display detailed information regarding various disks and volumes in your Mac. From here, please note the identifier of the disk you wish to format (like disk2 or disk1).
Step 3. Great! Once you have noted the identifier, use the "eraseDisk" command to erase the entire disk or the "eraseVolume" command to just erase a volume.
Step 4. The entire format of the diskutil command is diskutil eraseDisk . For instance, to format the disk2 in the HFS+ format, you can just enter the command "diskutil eraseDisk HFS+ DISK disk2" and press the return key.
Step 5. After that, just wait for the commands to process as your selected disk would be formatted in the supported file system.
As stated above, if your Mac is running on an outdated firmware version, then it can encounter the Disk Utility erase process that has failed the problem. Thankfully, it can easily be fixed by updating your Mac to its latest supported firmware. You can look for the latest update for macOS from the App Store. Alternatively, you can also click on the Apple logo from the top, go to System Preferences > Software Update and check for updates from here.

Similarly, you can try to erase the entire disk as well to further diagnose the problem. In this way, you can be sure whether the problem is with the entire disk or selected volumes.
If you are getting the Disk Utility to erase the process has failed error while formatting an external device, then you should follow this drill.

Step 2. Now, select the external device from the sidebar and click on the "Erase" button. As the following pop-up would be launched, go to its Security Options.
Step 3. From here, you can just adjust the security level for formatting the external device. I would recommend keeping the security level on the lower side to avoid getting the erase process has failed error on Mac.

There can be different reasons for formatting a hard drive or an external device on Mac. Some of them can be as follows:
It doesn't matter what your reason for formatting a hard drive or external device is – the process is extremely easy. I have already provided a smart solution to format a disk via Terminal above that you can follow. Although to format the disk via Mac's graphic user interface, the following steps can be taken.
Step 1: Launch the Disk Utility application
As you know, Disk Utility is responsible to run formatting and erasing operations on the disk. Therefore, you can just go to Finder > Applications > Utility and launch the Disk Utility application from here.
Step 2: Select a Disk or Device to format
Now, you can view a list of all the available disks and the connected devices on the sidebar of the Disk Utility application. If you want, you can go to the dropdown menu from the top-left corner to view all volumes and devices. From here, you can just select a disk, volume, or even an external device that you wish to format.
Step 3: Erase the selected disk
After selecting the internal drive or the external device of your choice, just go to the Disk Utility toolbar on the right and click on the "Erase" button.
This will launch a pop-up window so that you can make the needed changes to format the drive. For instance, you can give it a new name, change its file system, or even its partitioning scheme. After making the appropriate changes, just click on the "Erase" button and wait for a while as the selected drive would be erased.
Needless to say, when we format a disk, all the saved data in it is automatically erased. Therefore, if you don't want to lose your important files in the process, then consider taking a backup of your data in advance. For instance, you can manually copy your data and save it in another location (like another volume or an external hard disk). Apart from that, you can also use Time Machine to take an entire backup of your drive that you can later restore.
Though, if you have not taken a prior backup and have formatted your disk, then using a data recovery tool would be an ideal solution. You can take the assistance of Wondershare Recoverit, which is an extremely reliable data recovery application, supporting all the major macOS versions. By following a simple click-through process, you can get back your lost photos, videos, music, documents, and kinds of data.

The application also provides different filters for you to search for the files that you have lost. You can filter the searched results by file size, type, last modified date, and so on.
Step 3: Restore your deleted files
After completing the process, the application will automatically list the extracted content under different categories. You can now preview your photos, videos, music, documents, etc. here and select the files you wish to get back.
