Would you like to securely delete any important files without letting anyone know? If yes, then data sanitization will be the right choice. It is crucial for lifecycle management and data protection. If you delete any data from storage media, usually they don’t completely erase. 

If any hacker gets physical access to your device they can easily recover the deleted data. To prevent this occurrence data sanitization is used. It is intentional deletion of data to make it impossible to recover erased files. 

However, considering data migration is so complicated, it is best to know about the role of data sanitization. Continue reading about the role of data sanitization in data migration projects:

What is Data Sanitization?

The role of data sanitization is to delete data from a storage device permanently and safely. To prevent private or personal information from getting into the wrong hands data sanitization is done.

A list of methods used to sanitize data they are overwriting, degaussing, and physical annihilation. To render the original data unrecoverable, overwriting entails utilizing specialized software to write new data over the current data on a storage medium. 

Storage media is cleaned during sanitization to ensure that no data remains on the device and that no data, not even with advanced forensic techniques, can be recovered.

Why is Data Sanitization Important?

Computer devices can contain important business information even after they are deleted. Therefore, an organization’s computer systems are cleaned to remove any personal data before they are recycled.

This deletion is necessary because a growing amount of data is being saved digitally and because it poses a security concern if the device is sold to another user. It is essential to learn about the role of data sanitization because its importance has increased. Important data is now stored in larger, more complex datasets and retained electronically.

Electronic storage makes extraordinary data storage possible. Because of this, companies implement more intricate and thorough data sanitization processes to remove data before dismantling their systems.

Data sanitization guarantees that intellectual algorithms, trade secrets, and highly confidential company information are completely removed from decommissioned systems and devices. By doing this, valuable items are shielded from misuse or unwanted access while being deleted.

Methods of Data Sanitization

Data sanitization can primarily be achieved through the following methods:


Degaussing is a method of demagnetizing or neutralizing the magnetic field to destroy data. It stores data on magnetic media, including floppies and hard disk drives. Drive sanitization is the best option, and it destroys the drive. 

Physical Destruction:

This is one of the most extreme and successful ways to sanitize data. Shredded or burned hard drives are examples of physical damage to the storage device that prevents data recovery. Physical destruction is not eco-friendly however effective and keeps the device from being used again or sold.

With cloud-based data sharing and archiving, drive sanitization software security is becoming a real worry. Governments and private companies should naturally create and enforce data sanitization policies to guard against data loss and other security issues.

 Data Erasure:

This method uses software and ensures that no prior data is kept on the storage device by writing random 0s and 1s to each sector.

This type of drive sanitization is incredibly dependable because it can verify that every single bit of data was replaced. Additionally, auditable reports demonstrating the successful sanitization of data can be generated. 

This approach has the advantage over physical destruction in that it leaves the gadget undamaged and permits it to be sold or utilized again.

Cryptographic Erasure: 

Cryptographic erasure is deleting or altering the media encryption key of a self-encrypting drive, including contemporary SSDs that store encrypted data. However, unencrypted areas, such as those holding pre-boot software, cannot be cleared using the crypto-erase method. 

It is essential to remember that while choosing data sanitization procedures, the importance of the data to be cleaned and the required level of security should be considered. It could require a range of tactics to achieve the necessary level of security.  Also, choose the best data recovery company if you want to retrieve the lost data.

Data Masking:

Data masking is a commonly employed approach to compliance methods that is mandated by certain compliance standards. The masking process entails producing fake copies of the data while maintaining its structural integrity.

Techniques for masking include randomness, word substitution, and character shuffles. The inability to reverse engineer the masked data version to get the original data values unites all these methods.

Final Thoughts

Recovery Squad has more than ten years of experience providing individuals and organizations with data care results. In addition to being experts in data recovery services, they were the first to offer data erasure services to remove data from various servers, PCs, and storage devices. 

Throughout the data deletion cycle, they ensure the protection and safety of your data. They also act as the best data recovery center and help recover lost data soon.
