A system technician is tasked with destroying several hard drives that contain PII. Which of the following would be the BEST method for disposing of the drives?

Shredding physically destroys the drive platters and components, making data recovery impossible regardless of the tools or expertise applied. This is the industry-standard method for sanitizing media containing sensitive data like PII when the drive will not be reused. NIST SP 800-88 classifies physical destruction as the highest assurance sanitization method.

A hard wipe (overwriting all sectors) can be effective but still leaves a theoretical possibility of forensic recovery and does not meet the highest standard for PII destruction when disposal is the goal.

A soft wipe typically only removes file system references without overwriting underlying data, making recovery trivially easy with standard forensic tools.

Deleting the partition table removes only the map to the data, leaving all actual data intact and easily recoverable with partition recovery tools.
