Which of the following is a common data removal option for companies that want to wipe sensitive data from hard drives in a repeatable manner but allow the hard drives to be reused?

Sanitization is the correct option because it involves a process that renders data unrecoverable for a given level of effort, while still allowing the media to be reused. This can include methods like overwriting the data multiple times with specific patterns. Formatting (quick or full) can make data appear gone but is often recoverable with specialized tools. Degaussing uses a strong magnetic field to destroy data on magnetic media, making the drive unusable afterward. Defragmentation reorganizes data on a drive to improve performance but does not remove or wipe data.
