• Check the box for “Quick Format” to speed up the process.
• Click “Start” and confirm the formatting process. Be aware that this will erase all data on the selected drive.
2. macOS:
• Open “Finder” and click on the “Applications” folder.
• Open the “Utilities” folder, then launch “Disk Utility”.
• In the left sidebar, select the hard disk drive you want to format.
• Click on the “Erase” tab.
• Choose the desired format (typically Mac OS Extended or APFS).
• Enter a name for the formatted drive.
• Click “Erase” and confirm the formatting process. Remember that all data on the selected drive will be permanently deleted.

It is important to note that formatting the hard disk drive using the built-in tool is not completely secure. Although it makes it difficult for the average user to recover the data, specialized software may still be able to retrieve some information. For additional security, you can proceed to the next step to use disk utility software.

Step 3: Use disk utility software

After performing the built-in formatting process, it is recommended to further enhance the security of your data deletion by utilizing disk utility software. Disk utility software offers advanced features and algorithms that can securely erase the contents of your hard disk drive, making it extremely difficult to recover any deleted data.

There are several disk utility software options available, both free and paid, that you can choose from. Some popular choices include:

1. CCleaner: CCleaner is a widely used disk utility software that offers a feature called “Drive Wiper.” This tool can securely erase the contents of your hard disk drive by overwriting the data multiple times, ensuring that it cannot be recovered.
2. DBAN (Darik’s Boot and Nuke): DBAN is a free and open-source software that specializes in securely wiping hard drives. It operates by booting the computer using a DBAN bootable disk or USB drive, and then securely erases all data on the selected drive by using different overwrite patterns.
3. BitRaser: BitRaser is a professional disk utility software that provides data erasure services for various storage devices, including hard disk drives. It offers advanced algorithms to wipe data, including DoD 5220.22-M, NIST 800-88, and more, making it virtually impossible to retrieve any deleted information.

Before using any disk utility software, ensure that you carefully follow the instructions provided by the software developer to perform a secure data erasure. It is important to note that the process may take some time, depending on the size of your hard disk drive and the software you are using.

By utilizing disk utility software, you can add an extra layer of security to your data deletion process, preventing any potential recovery of sensitive information. However, if you want to take data destruction a step further, you can proceed to the next step and physically destroy the hard disk drive.
