To prevent identity theft: Identity theft is when someone steals personally identifiable information and uses it for malicious or other selfish ends, usually fraud. For instance, the identity thief could use your information to apply for credit or access medical services. Ultimately your reputation is what suffers most when this happens.

To prevent a possible data breach: A data breach happens when confidential information is accessed without authorization from the owner. In other words, if your trade secrets, personally identifiable information, or other proprietary data falls into the wrong hands, your data has been breached. Besides loss of trust from your clients, you may suffer severe financial penalties for such a breach. Wiping your old external hard drives eliminates this risk.

To protect your business’s reputation: When sensitive information pertaining to your business falls into unscrupulous hands, your reputation is likely to suffer. It may take years to recover and for some businesses, you may never recover at all. Wiping old hard drives puts your mind at ease knowing that your business’ reputation is always intact.

To comply with data protection laws and government regulations: In most jurisdictions around the world, businesses, organizations, and other agencies that collect user information are mandated to protect it. Securely wiping your hard drives before retiring them is a sure way to comply with these regulations.
