What is an effective practice when returning electronic storage media to third parties for repair?

When returning electronic storage media to third parties for repair, it is important to ensure that the media does not contain any sensitive or confidential data that could be compromised or disclosed. One way to do this is to establish a contract with the third party that specifies the security requirements and obligations for the handling, storage, and disposal of the media. This contract should also include provisions for auditing, reporting, and remediation in case of any security incidents or breaches. The other options are not effective practices, as they either do not protect the data adequately (A), damage the media unnecessarily (B and C), or are not feasible or practical in some cases. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5, page 239; CISSP For Dummies, 7th Edition, Chapter 2, page 43.
