Destroying hard drive data is an essential practice to safeguard data privacy. We often replace our Laptops or MacBookwith new ones, and discard our old systems. If you do not destroy your personal data in the old hard drive before discarding it, there are chances that someone can access this data unlawfully. This is why it is important to wipe all personal and confidential data from the hard disk before selling or discarding your old PC or Mac.
Typically, we format the hard drive or simply delete old data before discarding a system. Not many of us know that formatting or deleting does not ensure permanent deletion of data. These are just temporary forms of deletion that reallocate data to some other location in the system, making it inaccessible to the user. The data, however, stays in your hard drive and any data recovery tool can be leveraged to recover such data.
There is a lack of awareness with regards to data erasure, and people with malicious intent are looking to take advantage of this vulnerability. This is the reason, it is even more important to understand various best practices on how you can permanently destroy data in a hard drive, so that it cannot be recovered even with the help of a data recovery software.

There are two ways to wipe data from a hard drive. The first method involves formatting/deletion which as explained above, doesn’t permanently erase files from the drive. The second method involves using a file erasure software. Both methods are explained step-by-step below:

Method 2: Using a File Erasure tool.
